MAN Diesel to Supply Korean Navy

July 6, 2011

MAN Diesel & Turbo signed a contract on April 7, 2011 with STX, the South Korean engine manufacturer, for the construction of 4 × 12V28/33D STC diesel engines. The four-stroke units are bound for a Republic of Korea Navy vessel currently under construction in Korea at Hanjin Heavy Industry Co., Ltd.

Under the project name LST-II, Hanjin is constructing the landing ship tank (LST) vessel, which has an approximate length of 127 m. The naval vessel features a CODAD (Combined Diesel and Diesel) propulsion configuration with the 4 × 12V28/33D STC diesel engines integrated with two twin-input/single-output gearboxes and two CP propellers. The four engines are each rated at 5,460 kW and 1,000 rpm, with each featuring a 10% overload capacity for 1 hour/6 hours.

The MAN 28/33 variant’s STC suffix denotes its sequential turbocharging system and its characteristic large torque envelope. Other engine characteristics include fast acceleration, lower fuel consumption, lower signature at intermediate and low loads, shock resistance, and elastic mounting. The engine is IMO Tier-II compliant.

Delivery date for the engines has been set for October 2012 with the landing ship due for delivery in September 2014. The contract is the result of another successful cooperation between MAN Diesel & Turbo and its long-standing, Korean partner – STX – and is the initial fruit of a new V28/33D licence.
