One of six: ready to go to work.

Ngieng Hock Sii of Rajang Maju Marine Industries reports that his yard has delivered a half-dozen Cummins-powered tugs to Coastal Contracts Bhd. of Sabah, Malaysia. Coastal is a Malaysia based firm offering services that “include build, charter, repair, maintain and trade of marine vessels, ranging from tug boats, oil barges, dump barges, landing craft to offshore support vessels and more.”

The new set of tugs are classed by NKK as NS*(TUG) MNS, Tug Unrestricted Navigation. They are 32 meters overall length with 9.144-beam and a 4.2-meter molded depth. Capacities include 212 tons of fuel oil, 32 tons of potable water and 24 tons of ballast water. The vessels are fitted with fuel oil transfer pumps rated at 10 cubic meters per hour with a 20-meter head and fresh water pumps to transfer up to 4.8 cu. m. per hour with a 19-meter head. Accommodation is provided for up to 14 persons in two single person cabins and six two-person cabins.

The main engines are a pair of Cummins KTA50 diesels each producing 1600 HP at 1800 RPM and turning four-blade nozzled propellers through Hitachi Nico MG5506 gears with 6:1 reduction. Two 80 kW generators are each powered by Cummins 6BT5.9-D(M) engines. A three-ton electro hydraulic windlass handles the stockless 570-kg anchors. On the aft deck a 40-ton towing hook supplements a single-drum towing winch with 40-ton brake. The tug has a 40-ton bollard pull.

The wheelhouse includes an aft control station with a clear view of the working deck.
