About IMCA

Who We Are

We are the International Marine Contractors Association (IMCA), a leading trade association representing the vast majority of contractors and the associated supply chain in the offshore marine construction industry worldwide.

Our Members play a key role in the offshore oil & gas and renewable energy industries. Principally, this is through the engineering, procurement, construction, and installation of offshore wind farms and hydrocarbon production facilities, together with the ongoing life of field support and maintenance requirements of these assets.

IMCA is fully engaged in the energy transition for a sustainable and low carbon future. We play an important role in collaborating with our Members and other stakeholders in addressing the challenges of climate change, and in ensuring environmental sustainability, particularly in the context of our ocean resources.

IMCA was formed in 1995 through the merger of the Association of Offshore Diving Contractors (AODC) established in 1972, and the Dynamically Positioned Vessel Owners Association (DPVOA) established in 1989. Consequently, our operational roots and technical credentials are second to none in our industry.  We use our strong technical and safety focus to develop comprehensive best practice operating standards for the industry to improve its performance.

We are the leading voice for the offshore marine contracting industry.

Our Purpose

Enabling the development of the world’s marine energy resources – safely and sustainably.

Our Mission

Our mission is to improve performance in the marine contracting industry.

To achieve this, we leverage the expertise of our Members through conferences, seminars, and our large network of committees. We represent our Members in dialogue with other industry bodies, regulators, oil companies and renewable energy companies.

We are an international trade association. Our Members operate in the offshore construction industry around the world.

We exist for the benefit of our Members by promoting areas of common interest, such as health, safety, quality, environmental and technical standards. We have a well-respected, strong technical background and we are a communications platform for our members.

Our published technical and operational guidance is used globally across the offshore energy industry. Our work enables us to be a high-profile influencer in the industry, improving performance and driving-up standards.

Our Vision

Our vision is to be the global reference for developing all forms of marine energy resources in a low carbon future.
