International Maritime Organization, IMO

International Maritime Organization of the United Nations

The International Maritime Organization is a specialized agency of the United Nations responsible for the safety of maritime navigation and the prevention of marine pollution from ships. Its headquarters is located in London, United Kingdom. The organization was first established on January 6, 1959, formerly known as "Intergovernmental Maritime Consultative Organization". In May 1982 it was renamed the International Maritime Organization. The role of the International Maritime Organization (referred to as IMO) is to create a fair and effective regulatory framework for the shipping industry, which is generally adopted and implemented. This covers aspects including ship design, construction, equipment, staffing, operation and treatment, etc. to ensure safety, environmental protection, energy saving and safety in these aspects.

    History of IMO

    In the mid-19th century, some countries proposed that a permanent international agency should be established to promote maritime security more effectively, but these desires were not realized until the establishment of the United Nations itself.

    In 1948, a convention was adopted at the Geneva International Conference to formally establish the International Maritime Organization, the Intergovernmental Maritime Consultative Organization.

    In 1958, the relevant conventions of the International Maritime Organization entered into force and the new organization met for the first time.

    The global search and rescue system was launched in the 1970s, and the establishment of the International Mobile Satellite Organization greatly improved the broadcast and other information provided by ships.

    In 1978, the 1007 amendments to the International Convention standard training, certification and duty seafarers entered into force.

    Greatly improve the standards of seafarers, give the International Maritime Organization itself the power to check government actions and parties need to submit information to the IMO regarding their compliance with the agreement.

    The main amendments and codes of the STCW Convention were completed in 2010, using the "Manila Amendment STCW Convention and Code".

    The Global Maritime Distress and Safety System (GMDSS) was adopted in 1988 and has been phased in since 1992.

    On July 1, 1998, it became an international safety management code applicable to passenger ships, oil and chemical tankers, bulk carriers, natural gas operators and cargo high-speed processes of 500 gross tons and above.

    In February 1999, the Global Maritime Distress and Safety System (GMDSS) became fully operational, ensuring that ships can be assisted almost anywhere in the world in distress. Even if the crew has no time to broadcast for help, the news will be automatically disseminated.

    On July 1, 2002, other cargo ships and mobile offshore drilling units of 500 gross tonnage and above began.

    In the 2000s, a new and comprehensive international shipping safety mechanism, including the international Ship and port facility safety (ISP) codes, which took effect in July 2004, which was focused on maritime safety, was made mandatory under the amendments adopted by SOLAS in 2002 .

    In 2005, the International Maritime Organization adopted the amendments to the Convention to suppress the illegal conduct (SUA) of the safety of maritime navigation, 1988 and its related agreements (2005 and Sua agreement), and in other matters, the introduction of a contract.

    The desire for rights is on the banner of another Contracting State on the ship, when the requesting party has sufficient reason to suspect that the ship, or a person is on the ship, or a crime stipulated in the forthcoming committee convention.

    International Maritime Organization

    "International Maritime Organization (IMO)" as a special UN agency, his mission is to promote shipping safety, environmental protection, efficiency and sustainability through cooperation.

    The realization of the mission depends on adopting the highest feasible and unified standard. These standards mainly include maritime safety, navigation efficiency, ship pollution prevention and control, consideration of relevant legal issues and effective implementation of IMO documents.

    What is the purpose International Maritime Organization?

    The purpose of the organization is to promote shipping technical cooperation among countries, encourage countries to promote maritime safety, improve ship navigation efficiency, prevent and control ships from marine pollution, adopt unified standards, and deal with related legal issues.

    The General Assembly is the highest authority, held every two years. Its task is to elect members, formulate work plans and financial budgets, and discuss technical and legal issues within the scope of the organization ’s mandate.

    Internal structure

    Maritime Safety Committee (MSC)

    MSC is the highest technical organization of the organization. It consists of all member states. The function of the maritime safety committee is to “consider any vessel related to navigation equipment, construction and equipment within the scope of the organization.

    In addition, the committee also needs to provide machinery to perform any duties assigned to it by the International Maritime Organization Convention or any obligations that may be undertaken in its work It is assigned to it or accepted in any international instruments and organizations.

    It is also responsible for considering and submitting recommendations and guidelines for possible safety conferences.

    Marine Environmental Protection Committee ((MEPC))

    Any issue considered by all member states and authorized organizations is related to prevention and control of ship pollution. In particular, it is concerned with adopting and amending the conventions and other regulations and measures to ensure their implementation.

    In 1985, the Marine Environmental Protection Committee was upgraded to a full constitutional status.

    The Institute provides suitable qualified candidates, especially from developing countries, with advanced facilities for advanced training, learning and research of international maritime law. Special emphasis was placed on the adoption of international regulations by the International Maritime Organization.

    Operation mode of International Maritime Organization

    GloBallast project

    The actions of the International Maritime Organization and other international entities respond to global threats to the health of the world’s oceans, and by further improving the transportation environment and sustainable socioeconomic development, reduce the negative impact on marine ecosystems.

    This project helps developing countries and their shipping industry to prepare for the implementation of the 2004 International Convention on the Control and Management of Ship Ballast Water and Sediments. In addition, it also helps the shipping industry overcome technical challenges through the Global Industry Alliance (GIA) and promotes global efforts to solve the most difficult problems facing the shipping industry.

    Maritime safety

    The International Maritime Organization has also developed and adopted international seafarer collision regulations and global standards, as well as relevant international conventions and regulations for search and rescue, the convenience of international maritime traffic, load lines, dangerous goods transportation and tonnage measurement.

    The comprehensive mandatory safety system for international shipping took effect on July 1, 2004, reflecting the international ship and port facility safety codes (isp codes), which contain detailed safety-related requirements for the government, port authorities and shipping companies in a mandatory part (part) , Together with a series of guidelines on how to meet these needs, non-mandatory part (Party B).

    Organization Members International Maritime Organization

    There are 40 members of the International Maritime Organization Council, which are divided into A, B and C categories. Among them, 10 category A directors are major shipping countries.

    The Council is the executive body of the International Maritime Organization.

    It is responsible for managing the organization’s work under the leadership of the General Assembly and performs all the functions of the General Assembly between the two conferences.

    Ten Class B directors are the countries with the largest maritime trade volume, and 20 Class C directors are regional representatives.

    The Council is an important decision-making body of the organization. The organization holds a conference every two years to re-elect the council and chairman. The elected chairman and the board of directors will serve for two years.

    China resumed its membership in the International Maritime Organization in 1973.

    At the 16th Congress in 1989, China was elected as a Class A member and has been re-elected to this day.

    World Maritime Day

    "World Maritime Day" is an important event of the International Maritime Organization, which first appeared in 1978.

    March 17, 1978 coincided with the twentieth anniversary of the entry into force of the International Maritime Organization Convention.

    In November 1977, the 10th General Assembly of the International Maritime Organization passed a resolution, deciding that March 17th will be "World Maritime Day" every year, and March 17th, 1978 will become the first World Maritime Day.

    In November 1979, the 11th General Conference of the International Maritime Organization revised this resolution to consider that the climate in September is more suitable for maritime activities, so the future World Maritime Day will be changed to a day in the last week of September.

    "World Maritime Day" is determined by the International Maritime Organization. In the last week of September each year, governments of all countries hold a celebration day of their own choice to draw people's attention to ship safety, the marine environment and the International Maritime Organization.

    Every year, the Secretary-General of the International Maritime Organization of the Ocean Day prepares a special announcement, proposing topics that require special attention.

    China's Navigation Day

    On April 25, 2005, the State Council approved the "Decision to start from 2005 on July 11

    "Navigation Day", also as the implementation date of "World Maritime Day" in China "," Navigation Day "has since become a government-led, universal participation, national legal activity day.

    As of 2013, nautical day has been in Shanghai , Qingdao, Shandong, and Taicang, Jiangsu held three commemorative nautical days.

    Development trend

    Through the tracking of the issues of the IM0 Maritime Safety Committee in recent years, it has been found that there are roughly three obvious trends in the development of the IM0 Maritime Safety Convention, including:

    1) From passive response to active prevention and control

    Throughout the revision history of the IMO maritime safety conventions, it can be found that they are almost all closely related to major shipwrecks and major oil pollution accidents.

    Although this passive response to the modification of the convention based on accident investigation and experience summary has also played a positive role in ensuring maritime safety.

    The international maritime community is not satisfied with the status quo, especially the United States, the European Union and other countries often use this as a Under the pretext of separate legislation, the trend of unilateral legislation has intensified.

    Based on the dual consideration of ensuring the safety of maritime navigation and maintaining its authority in the international maritime community, IMO began to think about the policy of proactive response.

    The proposal of FSA changed IMO's response to ship accidents from passive response to active prevention and control.

    Estimate the probability of the accident before the accident, and use this as a basis to determine the optimal allocation of resources to avoid accidents or reduce accidents.

    The probability of occurrence provides a basis for the formulation or modification of the convention by weighing the costs of risk control and the benefits generated.

    Because countries have different estimates and understandings of risks, the FSA provides a way for countries to fully consider the overall impact of the amendment of the convention on the shipping community and help all parties reach consensus.

    2) Encourage technological innovation in ship design and construction

    The introduction of GBS in IMO has made the means of meeting the requirements of IMO maritime safety conventions no longer so simple.

    The maritime community will change from passively accepting international standards to actively setting target-oriented ship construction standards.

    After the GBS comes into effect, the ship's standards will be unified, and the ways to reach this standard are diversified. The classification society regulations and ship standards need to be submitted to IMO by the classification society, and the IMO determines that it meets the GBS requirements, that is, it can meet the safety goals and functional requirements set by the IMO before it can be promoted as an international standard globally.

    In the process of complying with GBS, only by grasping the connotation and core technology of GBS can we participate in international competition. Shipbuilding enterprises whose shipbuilding technology does not meet the requirements of GBS will be eliminated by the market.

    All these will prompt shipyards, marine equipment manufacturers, etc. to increase research and development efforts, and to innovate ship design and construction technologies to expand their market share.

    3) Emphasize the application of human factor theory in maritime legislation

    In the 21st century, the shipping industry's attention to the human factor has reached an unprecedented height. How the requirements of the mandatory maritime safety, security and anti-pollution conventions developed by international organizations depend on seafarers.

    In some regions and countries, the shortage of seafarers has led to the imbalance between supply and demand.

    The issues related to human factors are related to human factors. To meet the needs of environmental protection, IMO has gradually increased its attention to the human factor.

    Not only reflected in the ISM rules and maritime investigation rules formulated by IMO, but also reflected in the IMO technical institutions-the Maritime Safety Committee and the Maritime Environmental Protection Committee, the code of conduct, namely "Marine Safety Committee and Maritime Environmental Protection Committee and its subordinate organizations and work Method Guidelines.
