Crew management for ship owners & vessel operators.
GabMarine and Oil Services Limited was incorporated in 2007. Since then we have been active in marine supplies, engineering and procurement, labour services, offshore construction and — at our core — onshore and offshore crew supply and platform/rig personnel.
Headquartered in the heart of Port Harcourt’s business district, with branch offices in Lagos, London and Houston, we are well positioned to become a leading player in the supply of qualified vessel crew to the oil, gas and maritime industries in Nigeria and beyond.
