The subsea support vessel Maersk Involver has been delivered to Danish offshore marine contractor Maersk Supply Service by COSCO (Dalian) Shipyard.
The delivery follows the Maersk Installer, who was handed over in October.
The two Stingray-class vessels are part of the US$470 million contract a subsidiary of COSCO Shipyard Group secured in August 2014 to build four subsea support vessels.
The vessels are of a Marin Teknikk design with length of 137 metres, and a beam of 27 metres. Accommodating 120 people, they are intended for a wide range of operations in deep and shallow water.
They have an 1,850-square-metre free deck area with sea-fastening features for project cargo, a Huisman 400-tonne active heave compensated crane, an SMST 100-tonne crane, and two work-class remotely operated vehicles capable of operating in up to 3,000 metres of water and with the option of being deployed over the side or through an internal moon pool.
