Independent Expertise. Trusted by the World’s Leading Energy Companies.
International Marine Assurance Services (IMAS) delivers independent, high-quality marine assurance services to ship owners, operators, and energy companies worldwide. As part of the Northern Marine Group, IMAS combines deep technical knowledge with a commitment to impartiality – ensuring that every audit, inspection, and assessment is conducted with integrity, precision, and professionalism. IMAS was established in 2024 as a sister company to Maritime Global Services (MGS), which has long provided exclusive marine quality assurance services to one of the world’s largest energy majors. While MGS continues to serve that client exclusively, IMAS was created to bring the same level of expertise and service to the wider market.
A Shared Ethos, Independent Operations
Though IMAS and MGS share a common heritage and operate under the Northern Marine Group umbrella, they are legally, commercially, and operationally distinct. This structure ensures that IMAS can act with complete neutrality — even when auditing vessels managed by other parts of the Group.
This independence is essential. It allows IMAS to place the needs of its clients above all else, delivering assurance services that are objective, transparent, and trusted.
