Who We Are

The Offshore Marine Service Association represents more than 225 member companies, including approximately 100 firms that own and operate marine service vessels. These sophisticated vessels, some 1200 in number, connect America with its offshore energy resources, providing every pipe, wrench, computer, barrel of fuel, and gallon of drinking water to rigs and platforms, as well as transporting tens of thousands of workers to and from the facilities. This critical flow of supplies keeps the heart of America's energy industry pumping around the clock.

In addition to its members that own and operate vessels, OMSA’s associate members include shipyards, surveyors, vessel equipment manufacturers and distributors, training providers, financial institutions, attorneys, and accountants.


OMSA is the voice for this important and vibrant industry, representing its members’ interests before Congress, the Coast Guard, Customs and Border Protection, the Maritime Administration, the Environmental Protection Agency, the International Maritime Organization (IMO) and other federal, state and local officials.


Throughout its history, OMSA has successfully represented the industry on regulatory and legislative issues including vessel inspections, crewing, licensing, and international safety and environmental treaties.


OMSA also provides its members with effective tools to ensure the safety, security and environmental responsibility of their vessels and crew in compliance with government and industry standards.


OMSA is committed to ensuring the vitality and stability of the offshore marine industry.
