Next Generation Chase Vessel Deal
In the past months Dutch Saltwater Engineering designed and engineered two new generation chase vessels for fellow countrymen Rederij Groen. In addition to the technical aspects Saltwater also managed the tender process, which was concluded at the Europoort exhibition by awarding the build of both vessels to Dutch Maaskant Shipyards. On their 2013 delivery, the vessels will go directly into charter service for WesternGeco, to support their seismic survey fleet.
Considering the fact that these vessels have to operate for long periods in severe adverse weather conditions, a highly specific lines plan was developed for both comfort and efficiency. The operating speed, during seismic chase operations, is mainly about 4 to 5 knots which can result 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 to reduce pitching.
Dimensions
The main dimensions of the vessels are: length 37.40 m, beam 9.30 m, depth 4.60m, fuel oil capacity 200 cu. m and potable water cu. m. The vessels have refrigerated and dry storage capability as well as ample space on deck for the stowage of several containers. The classification of the vessels will be LRS +100A1, EP, Ice Class 1E, UMS, SCM, IWS, [+] LMC, with a top speed of 14 knots.
