VLAARDINGEN, the Netherlands -- Heerema has awarded Ulstein Sea of Solutions (USOS) a contract for further engineering of its new deepwater monohull construction vessel, in association with the DSME shipyard in South Korea.

In February, Heerema contracted USOS for the vessel’s design, later issuing the design, construction, testing, commissioning, and delivery contract to DSME.

The self-propelled, 211.5-m (694-ft) long DP-3 deepwater construction vessel is an adapted version of the Ulstein SOC 5000 design.

Heerema’s vessel features a revolving heavy lift capability of 4,000 metric tons (4,409 tons), deepwater lowering equipment for depths up to 3,500 m (11,483 ft), and a pipelay tower for J-lay and reel-lay operations via a moonpool. The hull configuration is designed for transit speeds of 12-14 knots and optimized motion characteristics. The DP-3 system is powered by 2 x 6.5 MW and 4 x 3.2 MW thrusters.

Following the award to DSME, USOS signed a contract with DSME last month for further vessel engineering and integration of equipment designed by Huisman.
