The delivery of the ‘7-Oceans’ to offshore services company Rederij Groen (Scheveningen, the Netherlands) marks a new milestone in Offshore Support Vessel construction. The vessels have been designed in close cooperation with both Rederij Groen and their customer. The Seismic Research Support Vessel is constructed by Maaskant Shipyards Stellendam, part of Damen Shipyards Group, and the first of a series of three identical vessels.
Charterer Dolphin Geophysical opted for a 35m design from Vestvaerftet in Denmark. This design is even closer to a fishing vessel compared to the two 40m newbuilds Maaskant delivered to Rederij Groen last year.
For optimal manoeuvrability two Veth azimuth stern drives (ASD) were chosen. They are each driven by an active front end, frequency controlled electric motor of 500 kW each. Power is generated by three Caterpillar C18 generator sets of 525 kVA. Also a 90 kW electric bow thruster is fitted.
Accommodation is arranged for a crew of 6 with extra capacity for 8 service crew. The electronic package complies with an A4 service area, which enables the vessel, in combination with the ICE-class notation, to operate in Artic areas. The deck arrangement is similar to the earlier delivered SRSV’s Astra-G and Aquarius-G, which have been proven to be efficient in their first year of operation.
