FLAMMABILITY

Flammable Limits

·        A mixture of hydrocarbon gas and air cannot ignite, unless its composition lies within a range of gas-in-air concentrations known as the flammable range.
·        The lower limit of the range, known as the "lower flammable limit", is any hydrocarbon concentration below which there is insufficient hydrocarbon gas to support combustion.
·        The upper limit of the range, known as the "upper flammable limit", is any hydrocarbon concentration above which air is insufficient to support combustion.
·        The flammable limits vary somewhat for different pure HC and for the gas mixtures derived from different petroleum liquids.
·        However in practice the lower and upper flammable limits of oil cargoes carried in tankers is for general purposes taken to be 01and 10 % hydrocarbon by volume, respectively.

Flammable Range Diagram



Hydrocarbon gas/air/inert gas mixtures effect on flammability

1.     Any point on the diagram represents a hydrocarbon gas/air/inert gas mixture, specified in terms of its hydrocarbon and oxygen content.
2.     Hydrocarbon/air mixtures, without inert gas, lie on the line AB, the slope of which shows the reduction in oxygen content as the hydrocarbon content increases.
3.     Points to the left of AB represent mixtures whose oxygen content is further reduced by the addition of inert gas.

·        The flammable range for HC gas is between 1 – 10%, and for O2 between 11.5 - 21%.
·        If 10% of CH gas is introduced in air, the proportion of oxygen reduces to 21x 90/100= 18.9% (Point D)
·        When O2 is minimum (11.5%), CH gas must be at least 1.5% (Point E).
·        At 1% CH gas, the oxygen must be at least 20.8% for the mixture to be flammable (Point C).
·        If the concentration of CH gas and O2 is outside the flammable range, the mixture will not burn.   

Dilution of CH Gas

·        When we dilute a CH gasair mixture with air (concentration as at Point F) the air will slowly replace the CH gas till the mixture becomes 100% air.
·        The concentrations of CH gas and O2 will take the path F A. 
·        This passes through the flammable range. At some time during the dilution, the mixture could explode if a spark was applied.
·        We must try to avoid passing through the flammable range during this dilution with air.
·        To do this the mixture is diluted with inert gas (along the path FH) till a point H is reached which is reached below the critical dilution line. As inert gas is added to hydrocarbon/air mixtures, the flammable range progressively decreases, until the oxygen content reaches a level generally taken to be about 11 per cent by volume, at which no mixture can burn
·        This is checked by sampling and testing the atmosphere with gas measuring instruments. If now O2 (air) is let in freely, the dilution will take place along line HA.
·        This does not pass through the flammable range at any time causing no danger of fire or explosion.

Fuel oil density 

Fuel oil density is the absolute relationship between mass and volume at a stated temperature . the s.i unit is kg/m3 at a reference temperature typically 15c.
Knowledge of density is required for quantity calculations.the value also needs to be known in order to select the optimum size of gravity disc for the centrifuge.in addition to density gives an indication of other fuel characteristics including specific energy and ignition quality*(ccai).
Specific gravity of a substance is a ratio of the mass of a given volume to the mass of equal volume of water at the same temperature as it is ratio there are no units.
Relative density of a substance is the ratio of the mass of a given volume at a temperature t1 to the mass of given volumeof pure water at temperature t2 at specific gravity RD is a ratio and hence no units.for example RD at 20/4c.since 1m 3 of pure water at 4c has a mass of 1000kg,the density of a substance at t1c is equivalent to the relative density at t1/4c.
In the u.s.a and other countries the density of petroleum products is defined in terms of API gravity.this is an arbitrary scale adopted by the American petroleum institute for expressing the relative density of oils.
The terms density in vacuo or density in air are sometimes used on fuel delivery or bunker receipt notes.as density is the absolute relationship between mass and volume and not its weight to volume by definition is in vacuo.although often used,the term density in air is incorrect and should be referred as a weight factor.this is because a substance weighed in air is supported to a small extent by the buoyancy of the air acting on it.thus the weight of the liquid in air is slightly less than the weight in vacuo.there is no simple relationship between density and weight factor. But for bunker fuels the difference approximates to 1.1kg/m3.to convert density at 15c to the weight factor at 15c 1.1kg/m3 should be detected.

I.M.O (INTERNATIONAL MARITIME ORGANIZATION )

MARINESHELF publishes articles contributed by seafarers and other marine related sites solely for the benefit of seafarers .All copyright materials are owned by its respective authors or publishers.

As a specialized agency of the United Nations, IMO is the global standard-setting authority for the safety, security and environmental performance of international shipping. Its main role is to create a regulatory framework for the shipping industry that is fair and effective, universally adopted and universally implemented.
 
In other words, its role is to create a level playing-field so that ship operators cannot address their financial issues by simply cutting corners and compromising on safety, security and environmental performance. This approach also encourages innovation and efficiency.
 
Shipping is a truly international industry, and it can only operate effectively if the regulations and standards are themselves agreed, adopted and implemented on an international basis. And IMO is the forum at which this process takes place.
 
International shipping transports about 90 per cent of global trade to peoples and communities all over the world. Shipping is the most efficient and cost-effective method of international transportation for most goods; it provides a dependable, low-cost means of transporting goods globally, facilitating commerce and helping to create prosperity among nations and peoples.
 
The world relies on a safe, secure and efficient international shipping industry – and this is provided by the regulatory framework developed and maintained by IMO.
 
IMO measures cover all aspects of international shipping – including ship design, construction, equipment, manning, operation and disposal – to ensure that this vital sector for remains safe, environmentally sound, energy efficient and secure.
 
Shipping is an essential component of any programme for future sustainable economic growth. Through IMO, the Organization’s Member States, civil society and the shipping industry are already working together to ensure a continued and strengthened contribution towards a green economy and growth in a sustainable manner. The promotion of sustainable shipping and sustainable maritime development is one of the major priorities of IMO in the coming years.
 
Energy efficiency, new technology and innovation, maritime education and training, maritime security, maritime traffic management and the development of the maritime infrastructure: the development and implementation, through IMO, of global standards covering these and other issues will underpin IMO's commitment to provide the institutional framework necessary for a green and sustainable global maritime transportation system.
 

What exactly is IMO?

The International Maritime Organization is a specialized agency of the United Nations which is responsible for measures to improve the safety and security of international shipping and to prevent marine pollution from ships. It is also involved in legal matters, including liability and compensation issues and the facilitation of international maritime traffic. It was established by means of a Convention adopted under the auspices of the United Nations in Geneva on 17 March 1948 and met for the first time in January 1959. It currently has 170 Member States. IMO's governing body is the Assembly which is made up of all 170 Member States and meets normally once every two years. It adopts the budget for the next biennium together with technical resolutions and recommendations prepared by subsidiary bodies during the previous two years. The Council acts as governing body in between Assembly sessions. It prepares the budget and work programme for the Assembly. The main technical work is carried out by the Maritime Safety, Marine Environment Protection, Legal, Technical Co-operation and Facilitation Committees and a number of sub-committees.

The IMO slogan sums up its objectives: Safe, secure and efficient shipping on clean oceans

What does IMO do?

When IMO first began operations its chief concern was to develop international treaties and other legislation concerning safety and marine pollution prevention.

By the late 1970s, however, this work had been largely completed, though a number of important instruments were adopted in more recent years. IMO is now concentrating on keeping legislation up to date and ensuring that it is ratified by as many countries as possible. This has been so successful that many Conventions now apply to more than 98% of world merchant shipping tonnage.
Currently the emphasis is on trying to ensure that these conventions and other treaties are properly implemented by the countries that have accepted them. The texts of conventions, codes and other instruments adopted by IMO can be purchased from IMO Publications.

Who is the Secretary-General of IMO?

The current Secretary-General is Mr. Koji Sekimizu (Japan).

Why do we need an international organization to look after shipping?

Because shipping is an international industry. If each nation developed its own safety legislation the result would be a maze of differing, often conflicting national laws. One nation, for example, might insist on lifeboats being made of steel and another of glass-reinforced plastic. Some nations might insist on very high safety standards while others might be more lax, acting as havens for sub-standard shipping.

Where can I find statistics on the shipping industry?

Try the Knowledge Centre on this site.  IMO compiles statistics from external sources: International Shipping and World Trade - Facts and figures
There are also various external sources of information:

- http://www.ics-shipping.org/shipping-facts/shipping-facts gives an overview of the shiping industry.

- UNCTAD  produces an annual Review of Maritime Transport http://unctad.org/en/pages/publications/Review-of-Maritime-Transport-(Series).aspx

- IMO now reviews its own performance indicators.

IMO's Global Integrated Shipping Information System (GISIS) has a number of modules providing information submitted by Governments, including maritime casualties, reports on piracy and armed robbery, stowaways and so on. 

How does IMO implement legislation?

It doesn't. IMO was established to adopt legislation. Governments are responsible for implementing it. When a Government accepts an IMO Convention it agrees to make it part of its own national law and to enforce it just like any other law. The problem is that some countries lack the expertise, experience and resources necessary to do this properly. Others perhaps put enforcement fairly low down their list of priorities.

The result is that serious casualty rates - probably the best way of seeing how effective Governments are at implementing legislation - can potentially vary from flag to flag.

IMO is concerned about this problem and in 1992 set up a special Sub-Committee on Flag State Implementation (now renamed the Sub-Committee on Implementation of IMO Instruments (III))to improve the performance of Governments. Another way of raising standards is through port State control. The most important IMO conventions contain provisions for Governments to inspect foreign ships that visit their ports to ensure that they meet IMO standards. If they do not they can be detained until repairs are carried out. Experience has shown that this works best if countries join together to form regional port State control organizations.

IMO has encouraged this process and agreements have been signed covering Europe and the north Atlantic (Paris MOU); Asia and the Pacific (Tokyo MOU); Latin America (Acuerdo de Viña del Mar); Caribbean (Caribbean MOU); West and Central Africa (Abuja MOU); the Black Sea region (Black Sea MOU); the Mediterranean (Mediterranean MOU); the Indian Ocean (Indian Ocean MOU) and the Arab States of the Gulf (GCC MoU (Riyadh MoU)).
IMO also has an extensive technical co-operation programme which concentrates on improving the ability of developing countries to help themselves. It concentrates on developing human resources through maritime training and similar activities.

IMOadopted the Voluntary IMO Member State Audit Scheme, with the first vountary audits in 2006 and is now in the process of adopting amendments to make the scheme mandatory in 2016. 
The Audit Scheme is designed to help promote maritime safety and environmental protection by assessing how effectively Member States implement and enforce relevant IMO Convention standards, and by providing them with feedback and advice on their current performance. The Audit Scheme is designed to help promote maritime safety and environmental protection by assessing how effectively Member States implement and enforce relevant IMO Convention standards, and by providing them with feedback and advice on their current performance. 

What about the classification societies?

All ships must be surveyed in ordered to be issued certificates which establish their seaworthiness, type of ship, and so onand this is the responsibility of the flag State of the vessel. However, the flag State ("Administration") may "entrust the inspections and surveys either to surveyors nominated for the the purpose or to organizations recognized by it" (SOLAS Chapter 1, regulation 6).

In pracice these "recognized organizations" are often the classification societies.

The International Association of Classification Societies(IACS) is a Non-Governmental Organization which was granted Consultative Status with IMO in 1969.

What about pollution?

In 1954 a treaty was adopted dealing with oil pollution from ships. IMO took over responsibility for this treaty in 1959, but it was not until 1967, when the tanker Torrey Canyon ran aground off the coast of the United Kingdom and spilled more than 120,000 tons of oil into the sea, that the shipping world realized just how serious the pollution threat was. Until then many people had believed that the seas were big enough to cope with any pollution caused by human activity. Since then IMO has adopted a whole series of conventions covering prevention of marine pollution by ships, preparedness and response to incidents involving oil and hazardous and noxious substances, prevention of use of harmful anti-fouling systems and the international convention on ballast water management to prevent the spread of harmful aquatic organisms in ballast water.

The Marine Environment Protection Committee (MEPC) deals with all issues relating to marine environment protection as it relates to shipping.

Protecting the environment from shipping is not just about specific regulations preventing ships dumping oil, garbage or sewage. It is also about the improvements in safety - from mandatory traffic separation schemes to the International Safety Management (ISM) Code and improving seafarer training - which help to prevent accidents occurring.

The preservation of Special Areas and Particularly Sensitive Sea Areas is an important aspect of IMO's work. IMO adopts these areas - so that all Member States have an opportunity to view proposals and discuss any proposed measures, so that any which might impact on the freedom of navigation can be fully explored.

IMO's Technical Co-operation Programme is hugely important in ensuring Member States have the resources and expertise to implement IMO conventions relating to marine pollution prevention. Examples of programmes include: sensitivity mapping to identify which parts of a coastline are particularly vulnerable; training in oil spill response and contingency planning; the GloBallast project which is addressing ballast water management issues; and the Marine Electronic Highway in the Malacca Strait.

The IMO has a significant role to play in preserving the marine environment and ensuring that shipping does not have a negative impact. It is recognized that environmentally speaking in terms of energy needed for volume of cargo transported, shipping is one of the "greenest" transport methods.

What about climate change?

IMO is heavily engaged in the fight to protect and preserve our environment - both marine and atmospheric - and is energetically pursuing the limitation and reduction of greenhouse gas emissions from shipping operations. The Marine Environment Protection Committee has developed energy efficiency measures, both for existing and new ships, to enable a comprehensive package of technical and operational measures to be agreed. 

Doesn't IMO always aim for the lowest common denominator?

IMO usually tries to act on a consensus basis. This is because it is important that measures adopted by the Organization, which can have a major impact on shipping, achieve as much support as possible. A treaty that was supported by only 51 per cent of the IMO membership, for example, would be opposed by nearly half the shipping world. Not only would they not ratify the treaty concerned but they might go off and adopt an alternative treaty of their own, thereby dividing the maritime community. But this does not mean that the measures themselves are of a low standard. Governments that did not want high standards would not bother to join IMO. The Governments that do join IMO do so because they support the Organization's aims. Experience has show that the treaties adopted by IMO represent an extremely high standard and their acceptability can be shown by the fact that many of them are now almost universal in their coverage. SOLAS, for example, has been accepted by more than 156 countries and covers all but a fraction of the world merchant fleet.

How much does IMO cost?

IMO is a bargain. It is one of the smallest agencies in the United Nations system, both in terms of staff numbers (just 300 permanent staff) and budget. Teh IMO Assembly in 2013 approved a budget of £64,304,000 for 2014 to 2015.

This is less than half what it would cost to buy a medium sized oil tanker and represents only a fraction of the cost of the damage caused by an oil spill, for example (the Exxon Valdez spill in Alaska in 1989 has so far cost more than US$5 billion). If IMO is responsible for preventing just one oil tanker accident a year then it more than covers its cost.

The IMO budget is unique for another reason. Costs are shared between the 170 Member States primarily in proportion to the size of each one's fleet of merchant ships. The biggest fleets in the world are currently operated by Panama and Liberia and so they pay the biggest share of IMO's budget.

IMO used to be called "the rich man's club". Has it changed at all?

When IMO began operations in 1959 shipping was still dominated by a relatively small number of countries, nearly all of them located in the northern hemisphere. IMO tended to reflect this. But as the balance of power in the shipping industry began to change so did IMO. The Maritime Safety Committee, the senior technical body, was thrown open to all Member States (previously it had consisted only of 16 Members elected by the governing Assembly). The Council, which acts as governing body in between the two-yearly meetings of the Assembly, was increased in size from 18 to 24 Member States, then to 32 and in 2002 was increased still further to 40. This was done partly to take into account the growing membership of IMO, but also to ensure that the views of developing countries were properly represented. The biggest increase in Council membership has been to the section which takes geographical representation into account. In 1969 IMO became the first UN agency to make its Technical Co-operation Committee a permanent institution - an indication of the importance the Organization attaches to this subject.

Shouldn't IMO have some sort of police function?

It is sometimes said that IMO should have some sort of authority to enforce its regulations. This seems to imply the creation of a team of inspectors and a fleet of patrol boats crewed by officials with the right to board any ships they suspected of contravening IMO regulations. In practice, the creation of such a force would be financially enormous - it would mean recruiting hundreds, probably thousands of people - and politically impossible: most Governments would never agree to allow ships flying their flag to be boarded in international waters and any attempt to introduce a system of penalties and punishments would be even more unacceptable.

The "IMO" police force would duplicate the work being done already by individual Governments and there is no guarantee that it would make a significant impact on safety and pollution, certainly in relation to the cost involved. IMO has however been given the authority to vet the training, examination and certification procedures of Contracting Parties to the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), 1978. This was one of the most important changes made in the 1995 amendments to the Convention which entered into force on 1 February 1997. Governments have to provide relevant information to IMO's Maritime Safety Committee which judges whether or not the country concerned meets the requirements of the Convention. The result is a List of Confirmed Parties to STCW.

Why is IMO so slow?

The main purpose of IMO is to adopt international treaties which are intended to apply to as many ships as possible. Unanimity of this kind inevitably takes time - it depends on the speed with which Governments act, as well as IMO - and it can only be achieved at all by ensuring that the regulations adopted are very widely acceptable and this can take time.

But when speed is necessary IMO can act very rapidly indeed.
An example is the adoption in December 2002 of security measures - largely in response to the 11 September 2001 atacks in the United States.
In December 2003, IMO revised the rules on oil tanker single-hull phase-out, in response to the Prestige incident of 2002.
In another example, following the Estonia disaster of September 1994, in which a passenger ro-ro ferry sank with the loss of more than 900 lives, the then Secretary-General of IMO, Mr. William A. O'Neil, called for a complete review of ro-ro safety to be carried out by a special panel of experts. The panel's report was considered by the Maritime Safety Committee in May 1995 and amendments to the International Convention for the Safety of Life at Sea (SOLAS), 1974 were adopted in November. Special requirements concerning the crews of ro-ro passenger ships were included in amendments to the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), 1978 that were adopted in July 1995. All of this was done before the final report into the disaster had been issued.

A further example is provided by the 1995 amendments to the STCW Convention as a whole. Although IMO agreed some years ago to amend the Convention, the timetable originally envisaged would have meant that this would not have taken place before 1998 and the amendments themselves would not have entered into force until the next century. In May 1993 the Secretary-General urged the Maritime Safety Committee that this process be accelerated by using special consultants. The Committee agreed and the amendment procedure - which amounted to a complete re-writing of the Convention - was completed by July 1995. As a result the amendments entered into force in February 1997 - more than a year before the amendment conference would have been held under the original timetable.
IMO has improved its procedures over the years to ensure that changes can be introduced more quickly.

One of the most successful of these has been the process known as "tacit acceptance" which has been included in most technical conventions adopted by IMO since the early 1970s. The normal procedure for adopting amendments to an international treaty is by means of "explicit acceptance." This means that the amendments enter into force so many months after being accepted by a specified number of Parties to the original Convention. The number can be as high as two-thirds and if the parent convention has been accepted by a large number of countries it could mean 80 or more of them having to ratify the amendment before it becomes international law. Experience has shown that this can take decades to achieve - by which time the amendment itself is likely to be out of date. The tacit acceptance procedure means that amendments - which are nearly always adopted unanimously - enter into force on a set date unless they are specifically rejected by a specified number of countries.

Because of the care taken at IMO conferences to achieve unanimity very few rejections have ever been received and the entry into force period has been steadily reduced. In exceptional cases amendments can enter into force as little a year after being adopted. Apart from the speed, tacit acceptance also means that everyone involved knows exactly when an amendments will enter into force. Under the old system you never knew until the final acceptance was actually deposited with IMO.

Have shipping safety and the marine environment improved because of IMO?

Although we can say yes to this question with some confidence it is difficult to compare shipping today with that of thirty or forty years ago because of the great changes that have taken place in the industry during that period. In the 1950s shipping was dominated by a handful of traditional maritime countries. They built the ships, operated them, manned them - and provided the goods that were carried on them. Today most ships fly the flags of developing countries, their crews come from all over the world. Doubts have been expressed about the ability of some of these countries to maintain and operate ships to the high standards laid down in IMO regulations. Ships themselves have changed dramatically in size, speed and design and in addition economic factors mean that the average of ships today is much higher than it used to be. Despite these changes, safety standards around the world are generally good and have improved considerably since the late 1970s, when IMO treaties began to enter into force and the number of acceptances rose to record levels.

Statistics do not always tell the whole story. In the early 1980s, for example, a study carried out in the United Kingdom showed that the number of collisions between ships was much the same as it had been ten years before, indicating that the introduction of traffic separation schemes and other measures had not had much impact. But closer examination showed that the number of collisions had fallen dramatically in areas where IMO approved schemes had been adopted - but had risen by the same number in areas where nothing had been done. Generally speaking, the rate of serious casualties has not greatly changed during the last ten years or so. But in view of the changes taking place in shipping - notably the steady ageing of the world fleet -this is an indication that IMO measures are having an impact.

As far as pollution is concerned, the indications are that there has been a remarkable improvement in the amount of pollution caused by ships.  This is partly due to the tightening of controls through IMO conventions such as the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78) and partly to the introduction of better methods of controlling the disposal of wastes. According to a study carried out by the United States National Academy of Sciences oil pollution from ships fell by about 60% during the 1980s, coinciding with the entry into force of MARPOL 73/78.
Whilst statistics have to be used with care, it should be noted that the incidence of large spills is relatively low; a very few large spills account for a high percentage of the oil spilt. Nevertheless, it is generally acknowledged that oil spills from shipping have decreased significantly over the last 30 years.
All of this is encouraging. But IMO is aware that a great deal more needs to be done to improve safety and prevent pollution. It is now concentrating on making sure that Governments and the industry implement the measures that have been adopted more effectively - and on reducing the number of accidents at sea which are caused by human error. Since some estimates say that mistakes make up around 80% of the total the scope for improvement is enormous.
IMO is now monitoring performance indicators to assess the trends.

What about maritime security?

Maritime security is now an integral part of IMO's responsibilities. A comprehensive security regime for international shipping entered into force on 1 July 2004.

The mandatory security measures, adopted in December 2002, include a number of amendments to the 1974 Safety of Life at Sea Convention (SOLAS), the most far-reaching of which enshrines the new International Ship and Port Facility Security Code (ISPS Code), which contains detailed security-related requirements for Governments, port authorities and shipping companies. 

What is IMO doing about piracy?

Just a few short years ago, it seemed that the scourge of modern-day piracy was being beaten. The figures reveal quite clearly how the nature of the problem has changed. At the turn of the last century, the world's most notorious piracy areas were the Straits of Malacca and Singapore and the South China Sea. In 2000, there were a total of 471 acts of piracy or armed robbery against ships reported to IMO, of which 112 had taken place in the Malacca Strait and 140 in the South China Sea.
By 2008, the total number of attacks reported was down to 305 and the figures for the Strait of Malacca and the South China Sea were down to 2 and 71, respectively. But, by contrast, the figure for East Africa had risen from just 13 in 2004 to 135 and, for West Africa, it had increased from 23 in 2004 to 51 in 2008.
Regional cooperation among States has an important role to play in solving the problem of piracy and armed robbery against ships, as evidenced by the success of the regional anti-piracy operation in the Straits of Malacca and Singapore. The Regional Cooperation Agreement on Combating Piracy and Armed Robbery against ships in Asia (RECAAP), which was concluded in November 2004 by 16 countries in Asia, and includes the RECAAP Information Sharing Centre (ISC) for facilitating the sharing of piracy-related information, is a good example of successful regional cooperation which IMO seeks to replicate elsewhere.
In January 2009, an important regional agreement was adopted in Djibouti by States in the region, at a high-level meeting convened by IMO. The Code of Conduct concerning the Repression of Piracy and Armed Robbery against Ships in the Western Indian Ocean and the Gulf of Aden recognizes the extent of the problem of piracy and armed robbery against ships in the region and, in it, the signatories declare their intention to co operate to the fullest possible extent, and in a manner consistent with international law, in the repression of piracy and armed robbery against ships.
Implementation of the Djibouti Code of Conduct has been helping to:
  • improve communications between States;
  • enhance the capabilities of States in the region to deter, arrest and prosecute pirates;
  • improve States' maritime situational awareness; and
  • enhance the capabilities of local coast guards.
IMO has recently established a multi-donor trust fund to support maritime security capacity-building projects in teh States surrounding teh Gulf of Guinea. 

How can I become a member of IMO?

Only a country can become a Member of IMO. IMO currently has 170 Member States.

Shipping and other interests are represented at IMO through Inter-Governmental Organizations (IGOs) which have concluded agreements of co-operation with IMO and Non- Governmental Organizations (NGOs) in Consultative Status with IMO.

Individuals wishing to raise an issue at IMO should approach their national maritime administration or appropriate IGO or NGO.

How can I get a job at IMO?

Current vacancies are posted in the About section under Careers.

What is technical co-operation?

The Technical Co-operation Programme is designed to assist Governments which lack the technical knowledge and resources that are needed to operate a shipping industry successfully. Any Member State can apply to IMO for assistance with specific projects.

What is the GMDSS?

The Global Maritime Distress and Safety System (GMDSS) is an integrated communications system using satellite and terrestrial radiocommunications to ensure that no matter where a ship is in distress, aid can be dispatched. Under the GMDSS, all passenger ships and all cargo ships over 300 gross tonnage on international voyages have to carry specified satellite and radiocommunications equipment, for sending and receiving distress alerts and maritime safety information, and for general communications. The GMDSS became fully effective from 1 February 1999. 

Where can I obtain the text of the IMO conventions?

Texts of IMO Conventions can be purchased via the Publications section. Texts can also be found in national public libraries and in the libraries of maritime training institutes.

For legal purposes, only the authentic texts and certified copies of Conventions and amendments should be used. Please note that texts of IMO Conventions found on external websites may not be up to date. You should also contact your national maritime Administration.

Conventions ratified by a Government are adopted into national legislation and the national version will be available through the usual channels (official bulletins, etc).

How can I contact IMO?

Individuals wishing to raise an issue at IMO, or wanting information on implementation of IMO instruments in their country or on their vessel, should approach their national maritime administration or appropriate IGO or NGO.

I am a student doing research - how can I find more information?

See the Knowledge Centre section as well as the other sections of the website. The Site Index can help you find information on a specific subject while external search engines can also help.

While we will endeavour to answer specific queries we expect students to research thoroughly on the website before emailing IMO.

WHAT IS ISO 9001 ; ISO14001 AND OHSAS

MARINESHELF publishes articles contributed by seafarers and other marine related sites solely for the benefit of seafarers .All copyright materials are owned by its respective authors or publishers.

ISO 9001

 The ISO 9001 certificate is suitable for all sizes of organisation and is well established around the world as an invaluable quality management system. It is suitable for organisations in all industry sectors and will help your organisation to improve management processes to compete locally and/or globally.

The process encompasses the entire organisation and requires senior management buy-in, it is not just a function of the Quality Department. To achieve ISO 9001 certification your organisation needs to demonstrate that it can meet the regulatory requirements and apply the system effectively to be of real benefit to your customers.
As an ISO 9001 certified organisation you will have implemented quality management system requirements for all areas of the business including:

    Facilities
    People
    Training
    Services
    Equipment

Continual Assessment
Achieving ISO 9001 standards is the first step of a process of continual improvement that will provide your organisation with the necessary management tools to improve working practices throughout the entire organisation.

UKAS accreditation
You will need to appoint a person to help you to carry out the internal assessments, assist in writing up the Quality Manual and procedures, and help you with getting certified.

ISO 9001 auditorWhen you are satisfied that your entire organisation is working within the guidelines of the quality management system, it is time to call in an ISO 9001 auditor. The audit can be done by a number of Certification bodies, however it is important to note that not all ISO 9001 auditing organisations are UKAS accredited. If you do not use a UKAS accredited auditor your certification could end up being worthless.
The ISO 9000 family of quality management systems standards is designed to help organizations ensure that they meet the needs of customers and other stakeholders while meeting statutory and regulatory requirements related to a product. ISO 9000 deals with the fundamentals of quality management systems, including the eight management principles upon which the family of standards is based.ISO 9001 deals with the requirements that organizations wishing to meet the standard must fulfill.
Third-party certification bodies provide independent confirmation that organizations meet the requirements of ISO 9001. Over one million organizations worldwide are independently certified, making ISO 9001 one of the most widely used management tools in the world today. Despite widespread use, the ISO certification process has been criticized as being wasteful and not being useful for all organizations.







ISO 14001

ISO 14001 sets out the criteria for an Environmental Management System (EMS). It does not state requirements for environmental performance, but maps out a framework that a company or organization can follow to set up an effective EMS. It can be used by any organization that wants to improve resource efficiency, reduce waste, and drive down costs. Using ISO 14001 can provide assurance to company management and employees as well as external stakeholders that environmental impact is being measured and improved.ISO 14001 can also be integrated with other management functions and assists companies in meeting their environmental and economic goals.
ISO 14001, as with other ISO 14000 standards, is voluntary (IISD 2010), with its main aim to assist companies in continually improving their environmental performance, while complying with any applicable legislation. Organizations are responsible for setting their own targets and performance measures, with the standard serving to assist them in meeting objectives and goals and in the subsequent monitoring and measurement of these (IISD 2010).
The standard can be applied to a variety of levels in the business, from organizational level, right down to the product and service level (RMIT university). Rather than focusing on exact measures and goals of environmental performance, the standard highlights what an organization needs to do to meet these goals (IISD 2010).

ISO 14001 is known as a generic management system standard, meaning that it is relevant to any organization seeking to improve and manage resources more effectively. This includes:
  • single-site to large multi-national companies
  • high-risk companies to low-risk service organizations
  • manufacturing, process, and the service industries, including local governments
  • all industry sectors including public and private sectors
  • original equipment manufacturers and their suppliers.
All standards are periodically reviewed by ISO to ensure they still meet market requirements. The current version of ISO 14001 – ISO 14001:2004 is under review as of April 2012.

Basic principles and methodology

These are based on the well-known Plan-Do-Check-Act cycle.

Plan--establish objectives and processes required

Prior to implementing ISO 14001, an initial review or gap analysis of the organization’s processes and products is recommended, to assist in identifying all elements of the current operation and, if possible, future operations, that may interact with the environment, termed "environmental aspects" (Martin 1998). Environmental aspects can include both direct, such as those used during manufacturing, and indirect, such as raw materials (Martin 1998). This review assists the organization in establishing their environmental objectives, goals, and targets, which should ideally be measurable; helps with the development of control and management procedures and processes; and serves to highlight any relevant legal requirements, which can then be built into the policy (Standards Australia/Standards New Zealand 2004).

Do--implement the processes

During this stage, the organization identifies the resources required and works out those members of the organization responsible for the EMS’ implementation and control (Martin 1998). This includes establishing procedures and processes, although only one documented procedure is specified related to operational control. Other procedures are required to foster better management control over elements such as documentation control, emergency preparedness and response, and the education of employees, to ensure that they can competently implement the necessary processes and record results (Standards Australia/Standards New Zealand 2004). Communication and participation across all levels of the organization, especially top management, is a vital part of the implementation phase, with the effectiveness of the EMS being dependent on active involvement from all employees.

Check--measure and monitor the processes and report results

During the 'check' stage, performance is monitored and periodically measured to ensure that the organization’s environmental targets and objectives are being met (Martin 1998). In addition, internal audits are conducted at planned intervals to ascertain whether the EMS meets the user's expectations and whether the processes and procedures are being adequately maintained and monitored (Standards Australia/Standards New Zealand 2004).

Act--take action to improve performance of EMS based on results

After the checking stage, a management review is conducted to ensure that the objectives of the EMS are being met, the extent to which they are being met, and that communications are being appropriately managed; and to evaluate changing circumstances, such as legal requirements, in order to make recommendations for further improvement of the system (Standards Australia/Standards New Zealand 2004). These recommendations are incorporated through continual improvement: plans are renewed or new plans are made, and the EMS moves forward.

Continual Improvement Process

ISO 14001 encourages a company to continually improve its environmental performance. Apart from the obvious- the reduction in actual and possible negative environmental impacts- this is achieved in three ways:
  • Expansion: More and more business areas get covered by the implemented EMS.
  • Enrichment: More and more activities, products, processes, emissions, resources, etc. get managed by the implemented EMS.
  • Upgrading: An improvement of the structural and organizational framework of the EMS, as well as an accumulation of know-how in dealing with business-environmental issues.
Overall, the CIP concept expects the organization to gradually move away from merely operational environmental measures towards a strategic approach on how to deal with environmental challenges.

Benefits

ISO 14001 was developed primarily to assist companies with a framework for better management control that can result in reducing their environmental impacts. In addition to improvements in performance, organizations can reap a number of economic benefits including higher conformance with legislative and regulatory requirements (Sheldon 1997) by adopting the ISO standard. By minimizing the risk of regulatory and environmental liability fines and improving an organization’s efficiency (Delmas 2009), benefits can include a reduction in waste, consumption of resources, and operating costs. Secondly, as an internationally recognized standard, businesses operating in multiple locations across the globe can leverage their conformance to ISO 14001, eliminating the need for multiple registrations or certifications (Hutchens 2010). Thirdly, there has been a push in the last decade by consumers for companies to adopt better internal controls, making the incorporation of ISO 14001 a smart approach for the long-term viability of businesses. This can provide them with a competitive advantage against companies that do not adopt the standard (Potoki & Prakash, 2005). This in turn can have a positive impact on a company’s asset value (Van der Deldt, 1997). It can lead to improved public perceptions of the business, placing them in a better position to operate in the international marketplace (Potoki & Prakash 1997; Sheldon 1997). The use of ISO 14001 can demonstrate an innovative and forward-thinking approach to customers and prospective employees. It can increase a business’s access to new customers and business partners. In some markets it can potentially reduce public liability insurance costs. It can serve to reduce trade barriers between registered businesses (Van der Deldt, 1997). There is growing interest in including certification to ISO 14001 in tenders for public-private partnerships for infrastructure renewal. Evidence of value in terms of environmental quality and benefit to the taxpayer has been shown in highway projects in Canada.

Conformity Assessment

ISO 14001 can be used in whole or in part to help an organization (for-profit or not-for-profit) better manage its relationship with the environment. If all the elements of ISO 14001 are incorporated into the management process, the organization may opt to prove that it has achieved full alignment or conformity with the international standard, ISO 14001, by using one of four recognized options. These are:
  1. make a self-determination and self-declaration, or
  2. seek confirmation of its conformance by parties having an interest in the organization, such as customers, or
  3. seek confirmation of its self-declaration by a party external to the organization, or
  4. seek certification/registration of its EMS by an external organization.
ISO does not control conformity assessment; its mandate is to develop and maintain standards. ISO has a neutral policy on conformity assessment. One option is not better than the next. Each option serves different market needs. The adopting organization decides which option is best for them, in conjunction with their market needs.
Option 1 is sometimes incorrectly referred to as "self-certify" or "self-certification". This is not an acceptable reference under ISO terms and definitions, for it can lead to confusion in the market.The user is responsible for making their own determination. Option 2 is often referred to as a customer or 2nd-party audit, which is an acceptable market term. Option 3 is an independent third-party process by an organization that is based on an engagement activity and delivered by specially trained practitioners. This option was based on an accounting procedure branded as the EnviroReady Report, which was created to help small- and medium-sized organizations. Its development was originally based on the Canadian Handbook for Accountants; it is now based on an international accounting standard. The fourth option, certification, is another independent third-party process, which has been widely implemented by all types of organizations. Certification is also known in some countries as registration. Service providers of certification or registration are accredited by national accreditation services such as UKAS in the UK.

ISO 14001 and EMAS

In 2010, the latest EMAS Regulation (EMAS III) entered into force; the scheme is now globally applicable, and includes key performance indicators and a range of further improvements. Currently, more than 4,500 organisations and approximately 7,800 sites are EMAS registered.

Complementarities and Differences

ISO 14001‘s environmental management system requirements are very similar to those of EMAS. Additional requirements for EMAS include:
  • stricter requirements on the measurement and evaluation of environmental performance against objectives and targets.
  • government supervision of the environmental verifiers
  • strong employee involvement; EMAS organisations acknowledge that active employee involvement is a driving force and a prerequisite for continuous and successful environmental improvements.
  • environmental core indicators creating multi-annual comparability within and between organisations
  • mandatory provision of information to the general public
  • registration by a public authority.

ISO 14001 Use in Supply Chains

There are many reasons that ISO 14001 should be potentially attractive to supply chain managers, including the use of the voluntary standard to guide the development of integrated systems, its requirement for supply chain members in industries such as automotive and aerospace, the potential of pollution prevention leading to reduced costs of production and higher profits, its alignment with the growing importance of corporate social responsibility, and the possibility that an ISO-registered system may provide firms with a unique environmental resource, capabilities, and benefits that lead to competitive advantage.
Emerging areas of research are starting to address the use of this standard to show that ISO 14001 registration can be leveraged across the supply chain for competitive advantage. By looking at ISO 14001 registered firms, information from the study compared different amounts of integration and sustainability in the supply chain. Several research propositions and an empirical framework posit the impacts of ISO 14001 on supply chain design.
The propositions include:
  1. ISO registration leading to more proactive environmental management including process and performance measurement related to sustainability across a supply chain;
  2. That ISO-registered plants with formal environmental management systems will have higher levels of communication required between OEMs and Tier I suppliers;
  3. ISO-registered plants with direct relationships to other registered plants in their supply chain will have higher levels of waste reduction and cost efficiency than nonregistered plants;
  4. ISO-registered plants with direct relationships to other registered plants in the supply chain will have sustainable practices and projects with better ROI than nonregistered firms;
  5. ISO-registered plants with direct relationships to other registered plants will have higher levels of customer relationship management and will be positively associated with greater expansion opportunities and image than nonregistered plants;
  6. ISO-registered plants with direct relationships to other registered plants will have fewer issues with employee health and reduced numbers of safety incidents than nonregistered plants;
  7. ISO-registered plants with a direct relationship to other registered plants will have a strong positive relationship between formal communication, training, monitoring/control systems, and firm performance; and
  8. ISO-registered plants with a direct relationship to other registered plants will have higher levels of involvement and communication, which will be positively related to more internal and external integration with supply chain members
  9.  ISO 14001 was first published in 1996 and specifies the actual requirements for an environmental management system. It applies to those environmental aspects which the organization has control and over which it can be expected to have an influence.
    ISO 14001 is often seen as the corner stone standard of the ISO 14000 series. However, it is not only the most well known, but is the only ISO 14000 standard against which it is currently possible to be certified by an external certification authority. Having stated this, it does not itself state specific environmental performance criteria.
    This standard is applicable to any organization that wishes to:
    • implement, maintain and improve an environmental management system
    • assure itself of its conformance with its own stated environmental policy (those policy commitments of course must be made)
    • demonstrate conformance
    • ensure compliance with environmental laws and regulations
    • seek certification of its environmental management system by an external third party organization
    • make a self-determination of conformance


    OHSAS 18001
    OHSAS 18000 is an international occupational health and safety management system specification. It comprises two parts, 18001 and 18002 and embraces a number of other publications. For the record, the following other documents, amongst others, were used in the creation process:

    • BS8800:1996 Guide to occupational health and safety management systems
    • DNV Standard for Certification of Occupational Health and Safety Management Systems(OHSMS):1997
    • Technical Report NPR 5001: 1997 Guide to an occupational health and safety management system
    • Draft LRQA SMS 8800 Health & safety management systems assessment criteria
    • SGS & ISMOL ISA 2000:1997 Requirements for Safety and Health Management Systems
    • BVQI SafetyCert: Occupational Safety and Health Management Standard
    • Draft AS/NZ 4801 Occupational health and safety management systems Specification with guidance for use
    • Draft BSI PAS 088 Occupational health and safety management systems
    • UNE 81900 series of pre-standards on the Prevention of occupational risks
    • Draft NSAI SR 320 Recommendation for an Occupational Health and Safety (OH and S) Management System
    OHSAS 18001 is an Occupation Health and Safety Assessment Series for health and safety management systems. It is intended to help an organizations to control occupational health and safety risks. It was devloped in response to widespread demand for a recognized standard against which to be certified and assessed. OHSAS 18001 (officially 'BS OHSAS 18001:2007') is an internationally applied British Standard for occupational health and safety management systems. It exists to help all kinds of organizations put in place demonstrably sound occupational health and safety performance. It is a widely recognized and popular occupational health and safety management system .Organizations worldwide recognize the need to control and improve health and safety performance and do so with occupational health and safety management systems (OHSMS). However before 1999 there was an increase of national standards and proprietary certification schemes to choose from. This caused confusion and fragmentation in the market and undermined the credibility of individual schemes. ts supporters claim that an occupational health and safety management system (OHSMS) promotes a safe and healthy working environment by providing a framework that helps organizations to: identify and control health and safety risks; reduce the potential for accidents; aid legal compliance; and improve overall performance.
    The OHSAS 18000 standards provide organizations with the elements of an effective safety management system which can be integrated with other management systems and help organizations achieve better occupational health and safety performance and economic objectives.
    BS OHSAS 18001 specifies requirements for an OH&S management system to help an organization develop and implement a policy and objectives, which take into account legal requirements and information about OH&S risks. It applies to all types and sizes of organizations and accommodates diverse geographical, cultural and social conditions.
    BS OHSAS 18002 provides guidance for establishing, implementing or improving a management system which is based on OHSAS 18001 and demonstrating successful implementation of OHSAS 18001.
    OHSAS 18001 can be aligned with existing ISO 9001 and ISO 14001 management systems. Historically many organizations start with the quality management system ISO 9001, then add the environment management requirements from ISO 14001. Many organizations now look at implementing all three standards at once which can minimize costs and disruption. The standards can be integrated using a standard such as BSI’s PAS 99.
