Rolls-Royce has won a contract from Island Offshore to design, power and equip an advanced UT 737 CD-type subsea construction vessel.

The subsea construction vessel, which will have an overall length of 96m and beam of 21m, will support demanding subsea projects, including constructing and servicing oil and gas wells on the sea bed up to 3,000m below sea level.

Singapore’s STX OSV Holdings (STX OSV) will build the vessel under the NOK500m ($87m) deal from Island Offshore awarded last month.

STX OSV Braila in Romania will deliver hull of the vessel, which will be equipped with one 125t offshore crane and Remotely Operated Vehicles (ROV) systems for operations up to 3,000m deep.

Rolls-Royce president of offshore Anders Almestad said, "This high tech vessel will showcase a combination of innovative technology and world-class, energy efficient design."

Scheduled to be delivered in the first quarter of 2014 from STX OSV Brevik in Norway, the ship will be designed with a moon pool, capable of accommodating 60 persons and will be built according to NOFO standards for oil spill response.

Rolls-Royce said that the design and fit out of the ship enables it to perform almost any duty in a deepwater oil field.

In addition to supporting subsea operations the vessel can also transport cargo to and from offshore oil and gas platforms and act as a rescue and oil spill response vessel.

The UT 737 CD subsea construction vessel will also be equipped with a diesel electric propulsion system, which will improve fuel efficiency and lower the vessels emissions.

Four Bergen engines will be installed in the vessel that will drive two Azipull thrusters and two side thrusters, which will work in unison with a dynamic positioning system to enable the vessel to maintain position when undertaking subsea activities.
