Greek offshore vessel investor Capital Offshore has signed a binding agreement to acquire 50% of Germany’s United Offshore Support (UOS) from funds managed by Hayfin Capital Management, with the combined operations to be branded “UOS Capital” once regulatory approvals are obtained.
The joint venture will integrate commercial, technical and crewing management across both partners’ offshore fleets, transferring Capital Offshore’s existing vessels to the new management platform.
Twelve high-specification newbuilds ordered by Capital Offshore — ten platform supply vessels (PSVs) and two multipurpose offshore support vessels (MPSVs) — are scheduled for delivery between 2026 and 2027 and are expected to join UOS Capital upon completion.
After the deliveries, UOS Capital is projected to manage more than 30 anchor handlers, PSVs and subsea support vessels owned or controlled by the shareholders.
Capital Offshore is an offshore vessel investment company within Capital Maritime Group, a privately held Greek shipping and maritime services group founded and led by Evangelos Marinakis. The group operates a diversified fleet across tanker, container, and offshore sectors and provides vessel management and chartering services through affiliated entities.

The company was formed through the consolidation of Hartmann Offshore’s assets and subsequent restructuring supported by Breakwater Capital and Hayfin Capital Management in 2017–2018.
