Turkey’s Sanmar Shipyards have delivered the first of a new class of Robert Allan Ltd designed ASD tugs to Italtugs for operation at a Sicilian oil terminal. Principle dimensions of the Civitavecchia include LOA of 32m with a beam of 13.2m and maximum draught of 6.4m. A forward bollard pull of ‘greater than 85 tonnes’ is provided via two MAN 7L27/38 main engines each developing 2,555kW at 800 RPM. These in turn power two Rolls-Royce type US25 CP Z-drive azimuth thrusters each with propellers of 2,800mm diameter turning within mild steel nozzles. They are driven by solid shafts with two Cardan joints and as well as the impressive bollard pull, a top speed in excess of 13 knots is also achievable. - See more at: http://www.maritimejournal.com/news101/tugs,-towing-and-salvage/first-of-new-class-from-sanmar#sthash.k3EkOThY.dpuf
