Cummins Vessel Reference #625
Thailand’s Marsun Co. Ltd. has built a reputation for quality high speed patrol craft and crewboats. Having built a number of their in-house designed 36-meter crewboats, they launched a 40-meter version earlier this year.
Delivered in February the Uniexpress 18 went into service in the Gulf of Thailand for owner Uniwise Offshore Ltd. transporting up to 70 workers to and from oil rigs. In addition to personel the boat can carry up to 50 tons of cargo on the 120 square-meter after deck. Tankage is provided for 50,000 liters of fuel and 20,000 liters of water.
Propulsion for the 40-meter crew boat is the same as that for Marsun’s 36-meter model. This is provided by three Cummins KTA38-M2 diesels each delivering 1350 BHP at 1950 RPM. The engines turn 1050-mm diameter Ni-Al-Bronze propellers through Twin disc MGX-6690SC gears with 1:2.47 ratios.
This power package pushed the boat at 23 knots at loaded 30 tons dwt with an 18-knot cruising speed. Interestingly the 40-meter long by 7.6-meter wide hull achieved over a knot more speed on sea trials than the 36-meter version of the 3.6-meter deep hull.
Accommodation is provided for a crew of ten on the Uniexpress 18, which has electrical power provided by a pair of 80 kw generator sets.
