SeaMar orders Multipurpose Offshore Support Vessel at Shipyard De Hoop

by Hans | March 26th, 2013

SeaMar Subsea BV has entered into a contract with Shipyard De Hoop for the construction of a Multipurpose Offshore Support Vessel. Custom designed to stringent environmental control, the diesel electric powered 65metre vessel will be constructed for low fuel consumption, clean ship / green passport / SPS2008 and high comfort class notation, making it the first offshore vessel to be built in the Netherlands to this specification.

The DP2 class vessel provides ergonomically designed accommodation for a total of 52 personnel in single or double cabins, complete with conference rooms, working offices, recreation rooms and a gymnasium.  The vessel will be manned and operated from the Netherlands, sailing under the Dutch Flag and registered in Den Helder.

The vessel’s main propulsion system consists of two 900kW azimuth thrusters at the stern and two bow thrusters, one of which is a 600kW tunnel thruster and the other a 400kW retractable azimuthing thruster. Four 995kW generators, with caterpillar C32 prime movers, power all of the above.

The state of the art multipurpose OSV will be completed and delivered in the second quarter of 2014. It incorporates several innovative design features, which will provide support to the offshore oil & gas and renewables markets. These features include a long jib length crane, triple moon pools, large under deck workshops and a four point mooring system. The vessel provides a total working deck space of 500m2 at a rated load of 5t/m2. In addition to this, the deck is strengthened locally at the stern to accommodate a 20t A-frame and around the moon pool where it is increased to a loading of 60t/m2.
