The delivery of the 7-Oceans to offshore services company Rederij Groen (Scheveningen, the Netherlands) is the first of a series of three identical custom built Seismic Research Support Vessels.
The vessels have been designed in close cooperation with both Rederij Groen and its customer. The Seismic Research Support Vessel is constructed by Maaskant Shipyards Stellendam, part of Damen Shipyards Group.
Close to a Fishing Vessel
Charterer Dolphin Geophysical opted for a 35 m design from Vestvaerftet in Denmark. This design is even closer to a fishing vessel compared to the two 40 m newbuilds Maaskant delivered to Rederij Groen last year.
Vessel Particulars
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. Furthermore, a 90 kW electric bow thruster is fitted.
Accommodation is arranged for a crew of six with extra capacity for eight 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.
