Incat Crowther has launched a 24m Catamaran Scientific Research Vessel. Built by Baltic Workboats in Estonia, Vėjūnas is a demonstration of the yard’s experience, capability and build quality. Vėjūnas also demonstrates Incat Crowther’s expertise in designing a vessel with a large, practical work deck area and excellent stability and seakeeping for scientific work.
Classed by DNV, Vėjūnas has completed sea trials and has been delivered to Lithuania’s Ministry of Environment for operation in the Baltic Sea. The vessel will monitor the Baltic Sea nearshore area and the Curonian Lagoon.
The aft deck features lower platform access, hydraulic A-Frame, 6,4tm Fassi deck crane and moon pool. The main deck cabin will feature two work spaces. To port will be a hydrological lab, with three workstations and bathroom. To starboard will be a chemical-biological laboratory with sinks, 4 workstations and 8 sqm storage room. At the forward end of the cabin is a crew mess and galley facilities.
The upper deck wheelhouse has excellent all round visibility with direct access to the foredeck. The hulls accommodate 11 crew members in 5 twin cabins and a single cabin for the captain. Each hull has a shower and toilet room.
Powered by a pair of Sisu CTIM84 main engines, each producing 302kW at 2100 rpm, Vėjūnas easily exceeded 14 knots top speed in recent trials. She will operate at a service speed of 12 knots. Is the vessel’s exceptional fuel economy of just 37,5l/nm at 10 knots. This gives Vėjūnas a range of over 2000 nm.
