  • ABThe International Marine Contractors Association (IMCA)is the international trade association representing offshore,marine and underwater engineering companies.

    IMCA promotes improvements in quality, health, safety,environmental and technical standards through the publication ofinformation notes, codes of practice and by other appropriatemeans.

    Members are self-regulating through the adoption of IMCAguidelines as appropriate. They commit to act as responsiblemembers by following relevant guidelines and being willing to beaudited against compliance with them by their clients.
