Kian Juan Dockyard in Miri, Sarawak, East Malaysia occupies 100 meters of river frontage on a 15-acre site in the Kuala Barm Industrial Estate. There is space for the fabrication of several vessels up to 80 meters and 2000 TDW at one time. In late March they had several vessels under construction including a pair of 29x9-meter tugs being built to a design by United Ship Design of Sibu. The full-bodied tugs have a double-chine design and a 4.26-meter molded depth.
Propulsions power is provided by a pair of Cummins KTA38 M2 engines producing 1200 hp each at 1800 RPM and turning nozzle-equipped 2x1.69-meter propellers through Twin Disc MG5301 gears with 5.947:1 ratios. Estimated bollard pull is 30 tons with a designed 11-knot light running speed. The 2400 hp boats are fitted with single drum towing winches with 600 meters of 48 m/m wire. Electrical power is provided by two Cummins 6BT-powered 80 Kw generator sets for each vessel.
Landing craft have evolved a long way from the ubiquitous boats that brought US Marines ashore on South Pacific islands in the closing days of World War II. These handy boats have grown dramatically in size and power over the years but they maintain the shallow draft and forward ramp that allows them to load or off-load in shallow ports with little or no pier infrastructure.

The shipyards of Miri and Sibu in East Malaysia have developed the landing craft to a sophisticated cargo carrier for both liquids and deck cargos. A recent example, designed by United Ship Design of Sibu, is the SK Line 11 from the Kian Juan Dockyard Sdn. Bhd of Miri, Sarawak. In spite of a length over all of 45.5 meters (149.28 feet) and a 10.9-meter (35.76 feet) the vessel has a draft of only 2.4-meters (7.87 feet). These dimension give the landing craft at huge open deck forward. Under the deck a number of tanks provide for fuel oil in 42-tonne operating tanks and 256-tonne long range or cargo tanks. Additional tankage provides for 98 tonnes of ship’s water and 364 tonnes of cargo water. Marine airbag
The boat is powered by a pair of 640 hp Cummins KTA19-M3 engines turning into Reintjes WAF364L gears with 4.481:1 gears to give the boat an eleven-knot design speed. Additional engines include a pair of Cummins 6BTA-powered 80 kW generator sets and a bow thruster engine. A three-level deckhouse set well aft includes two accommodation decks with bunks for up to 20 crewmembers. On the navigation bridge deck a davit is fitted to launch a rescue craft mounted there.

The SK Line 11 is one of several being built at Kian Juan Dockyard for a Malaysian customer and it will be registered in Kuching Malayasia. Recently a similar vessel was delivered from another Miri yard for a UK customer who will use it in the Falkland Islands. It seems likely that other owners around the world will find these vessels an attractive option for areas with limited dockage and infrastructure.
