Robert Allan Ltd (RAL) of Canada says that TOR Group of Companiesí (TOR) shipyard in Tuzla Bay (Istanbul), Turkey has delivered the 'Ben Owusu-Mensah', the third of three RAL-designed RAstar 3300 tugs for Ghana Ports & Harbours Authority (GPHA).

With keels for all three tugs laid on February 19th of 2019, these deliveries are especially notable for the speed of construction. The 38.2m x 12.8m tugs are equipped to fulfil various missions for the GPHA, including but not limited to ship-assist, fire-fighting, and pollution response. The Ben Owusu-Mensah and its sisters Josephine Asante and Commander KT Dovlo comfortably meet all contractual performance requirements, including 82t bollard pull and speeds in excess of 14 knots on trials. Main propulsion machinery comprises the first Cummins QSK95-M engines used in a tug application, each delivering 2,560kW at 1800 rpm, and driving 2.8m diameter Kongsberg US255S P30 fixed pitch Z-drives. Electrical power is generated by a pair of Cummins QSB7 gensets, each producing 136ekW at 50 Hz.

Ship-handling and towing needs are met with a Kongsberg hawser winch forward, with 225t brake holding load and a 100t SWL Mampaey tow hook aft. The Fi-Fi 1 class off-ship fire-fighting system is powered by a dedicated Cummins QSK38-M1 engine, driving a single 2,750 m3/h Marsis fire pump. A pair of Marsis water and foam capable monitors are mounted on the forward deckhouse top and include fog/jet nozzles. A water spray system is also outfitted. In addition to their primary ship-handling and fire-fighting duties, the tugs feature tankage for recovered oil, with a corresponding oil recovery notation. A Heila 25-2S folding knuckle boom crane on the aft deck of each tug provides additional utility with 8.6m reach.

Bureau Veritas is responsible for plan approval and classification of all three tugs, with notation: BV I ✠ Hull, ✠ Mach, Tug, Fire-Fighting 1 Waterspraying, Unrestricted Navigation, ✠ AUT-UMS, Oil Recovery Second-Line.
