Maersk Supply Service

What Maersk Supply Service does

Maersk Supply Service is a Denmark-domiciled (CVR 31 41 43 77) offshore marine services company founded in 1972 as part of the A.P. Møller-Maersk group. It provides vessel chartering and integrated project solutions to the offshore energy sector, with a primary focus on deep-water and ultra-deep-water operations in Brazil's pre-salt basins.

The company operates a fleet of anchor handling tug supply (AHTS) vessels and platform supply vessels (PSVs), including M-class and L-class designs with DP2 dynamic positioning and bollard pulls up to 260 tonnes. Core services include anchor handling, FPSO mooring installation and life extension, towing campaigns, rig moves, and — through a partnership with Alcatel Submarine Networks — Permanent Reservoir Monitoring installation using Optowave technology. The Integrated Solutions offering combines in-house engineering and project management with vessel execution for EPCI-style mooring projects.

Revenue is generated primarily through multi-year time charter contracts with energy majors (Petrobras, Shell Brasil, PetroRio) and integrated solutions contracts with EPCI partners (TechnipFMC, Alcatel Submarine Networks). Distribution is direct enterprise field sales with regional offices in Rio de Janeiro (HQ since November 2024), Aberdeen, St. John's, Lagos, Luanda, and Perth. Maersk Supply Service Brazil has operated as an independent company since November 2023 and is subject to a pending acquisition by a consortium led by ASM Texas Corp and FV Star One Limited, while the broader entity remains owned by A.P. Moller Holding.
