Interocean Marine Services

What Interocean Marine Services does

Interocean Marine Services is a UK-headquartered (Portlethen / Aberdeen) specialist marine consultancy founded in 2007 that delivers engineering, marine warranty, survey, inspection, HSSE, and emergency response services to the offshore oil and gas, maritime, and renewable energy sectors. The firm organizes its offering into three divisions — Maritime (seven service modules including compliance & risk management, engineering, marine consultancy, marine projects, marine warranty, moorings, and survey & subsea), Offshore O&G (construction support, inspection services, statutory inspection, UAV services), and Renewables (floating wind, inspection & maintenance, statutory inspection, survey & subsea, UAV, wind farm development support, and marine operations coordination) — providing a "total project solution" spanning planning, design, installation, operations, maintenance, and decommissioning.

The company operates a global office network spanning the UK, Norway, West Africa, North America, and the UAE, enabling mobilization of engineering teams into all major offshore basins. Its commercial model is B2B enterprise professional services delivered primarily under Master Services Agreements with energy-sector clients; a March 2026 MSA with JERA Nex bp (the 2025-formed JERA–bp offshore wind joint venture) is the most prominent named engagement, anchored from Aberdeen. The firm is privately held, has 51–100 employees, and does not publicly disclose revenue or pricing. It has no parent company, no disclosed funding rounds, and no recorded M&A activity, and in December 2025 received the IMCA Innovation and Technology Project Award for its asset management credentials.
