Dutch shipping company Rederij Groen has ordered two seismic research & support vessels (SRSVs) from Maaskant Shipyards Stellendam, part of the Damen Shipyards Group, for delivery in the first quarter of 2013.

Although Maaskant has broad experience in maintenance and repair of offshore support vessels, this order for the SRSV newbuilds is a first. Director Frits van Dongen said: “The Groen orders are a result of our approach towards offshore vessel design and construction and we are very proud indeed.”

The vessels have been designed in cooperation with Saltwater Engineering (Netherlands) to meet the needs and experiences of Groen. Considering the fact that these vessels have to operate for long periods in severe adverse weather conditions, a highly specific hull shape was developed for both comfort and efficiency. The operating speed, during seismic chase operations is normally about 4 to 5 knots which can result in wave slamming and severe pitching of the vessel. Taking this into account, the lines have been developed with V-shaped sections in the aft part creating diverting waves and U shaped sections in the forward area aimed at reducing pitching.

Both SRSV’s will be 40m long with a 9.30m beam and a depth of 4.60m. The 1,940kW power plant comprises two Caterpillar diesel engines which will give the vessels a design speed of 14 knots. The vessels will have refrigerated and dry storage capability as well as ample space on deck for the stowage of several containers. Classed by Lloyd’s Register, the new vessels will be capable of worldwide operations and have accommodation for 14 people.
