MAN Diesel & Turbo says that it signed a contract in April, 2011 with STX of South Korea, for four 12V28/33D STC medium speed engines, for a Republic of Korea Navy ship under construction at Hanjin Heavy Industry.

Under the project name LST-II, Hanjin is building 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 four diesel engines integrated with two twin-input/single-output gearboxes and two CP propellers. The engines are each rated 5,460kW at1,000rpm, with each featuring a 10% overload capacity for 1 hour/6 hours.

The STC suffix denotes that the engines are equipped with sequential turbocharging systems, in order to provide a characteristic large torque envelope. Other engine characteristics include:

  • fast acceleration;
  • lower fuel consumption;
  • lower signature at intermediate and low loads;
  • shock resistance;
  • elastic mounting for low noise and vibration; and
  • IMO Tier-2 compliance.

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