Damen Shipyards is further strengthening its involvement in the Brazilian offshore market with six Platform Supply Vessels, type PSV 4500, built under licence by Wilson, Sons (Santos, Brazil) for Wilson Sons Ultratug Offshore (WSUT). Two vessels have already been delivered, with the other four to be delivered during 2013.
Wilson, Sons is the largest operator of harbour tugs in Brazil and already has a large fleet of Damen vessels comprising Azimuth Stern Drive tugs and Platform Supply Vessels. The new 4,500dwt vessels measure 87m by 16m overall and have a large deck area. A diesel electric propulsion system comprising four Caterpillar 3512C generator sets, each of 1,570ekW at 1,800rpm, power two Rolls-Royce azimuth thrusters of 2,500kW.
Fixed pitch propellers, with nozzle, deliver a speed of 13 knots. Twin bow thrusters ensure good manoeuvrability, and the vessel has a dynamic positioning DP2 classification. There is accommodation for 14 crew and up to six passengers.
