International Marine Contractors Association (IMCA) is a leading international trade association for the marine contracting industry. It is a not for profit organisation with members representing the majority of worldwide marine contractors in the oil and gas and renewable energy industries.

IMCA was formed following the merger of the Association of Offshore Diving Contractors (AODC) with the Dynamically Positioned Vessel Owners Association (DPVOA) in 1995.


IMCA's mission is to improve performance in the marine contracting industry.

IMCA represents over 700 member organisations in over 60 countries.[1] It operates in five geographic regions of the globe (in Asia-Pacific, North America, Europe & Africa, Middle East & India and South America).[2] IMCA has a full-time secretariat in London that organises and manages the regional and technical committees. The extensive committee structure consists of elected member representatives who are experts in their field of operation.

As a trade association, IMCA is required to comply with international competition law and represents the industry on national and international forums, such as the International Maritime Organizaton.[3]
