The Committee is also required to provide machinery for performing any duties assigned to it by the IMO Convention or any duty within its cope of work which may be assigned to it by or under any international instrument and accepted by the Organization.

The MEPC, which consists of all Member States, is empowered to consider any matter within the scope of the Organization concerned with prevention and control of pollution from ships. In particular it is concerned with the adoption and amendment of conventions and other regulations and measures to ensure their enforcement.
The MEPC was first established as a subsidiary body of the Assembly and raised to full constitutional status in 1985.
The MSC and MEPC are assisted in their work by a number of sub-committees which are also open to all Member States:
- Sub-Committee on Human Element, Training and Watchkeeping (HTW);

The Legal Committee is empowered to deal with any legal matters within the scope of the Organization. The Committee consists of all Member States of IMO. It was established in 1967 as a subsidiary body to deal with legal questions which arose in the aftermath of the Torrey Canyon disaster.
The Legal Committee is also empowered to perform any duties within its scope which may be assigned by or under any other international instrument and accepted by the Organization.
Technical Cooperation Committee
The Technical Cooperation Committee is required to consider any matter within the scope of the Organization concerned with the implementation of technical cooperation projects for which the Organization acts as the executing or cooperating agency and any other matters related to the Organization's activities in the technical cooperation field.
The Technical Cooperation Committee consists of all Member States of IMO, was established in 1969 as a subsidiary body of the Council, and was institutionalized by means of an amendment to the IMO Convention which entered into force in 1984.
The Facilitation Committee was established as a subsidiary body of the Council in May 1972, and became fully institutionalised in December 2008 as a result of an amendment to the IMO Convention. It consists of all the Member States of the Organization and deals with IMO's work in eliminating unnecessary formalities and "red tape" in international shipping by implementing all aspects of the Convention on Facilitation of International Maritime Traffic 1965 and any matter within the scope of the Organization concerned with the facilitation of international maritime traffic. In particular in recent years the Committee's work, in accordance with the wishes of the Assembly, has been to ensure that the right balance is struck between maritime security and the facilitation of international maritime trade.
The Secretariat of IMO consists of the Secretary-General and some 300 international personnel based at the headquarters of the Organization in London.

The IMO Assembly in 2023 adopted the budget and work programme for 2024 to 2025.
The results-based budget for the 2024-2025 biennium is £83,653,000 comprising an appropriation of £40,923,000 for 2024 and an appropriation of £42,730,000 for 2025. This will be largely financed by contributions from Member States, of £73,153,000, comprising £35,572,000 for 2024 and £37,581,000 for 2025.
Contributions to the IMO budget are based on a formula which is different from that used in other United Nations agencies: the amount paid by each Member State depends primarily on the tonnage of its merchant fleet.
