Three SRSVs for RederijGroen
MaaskantShipyards Stellendam delivers custom-built offshore chasers
The delivery of the 7-Oceans to offshore services company RederijGroen (Scheveningen, the Netherlands) marks a new milestone in Offshore Support Vessel construction. The vessels have been designed in close cooperation with both RederijGroen and their customer. The Seismic Research Support Vessel (SRSV) 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 RederijGroen last year.
For optimal maneuverability, two Vethazimuth 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 (CAT) C18 generator sets of 525 kVA. Also 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 Arctic areas.
The deck arrangement is similar to the earlier delivered SRSVs Astra-G and Aquarius-G, which have been proven to be efficient in their first year of operation.
