FIRST ORDERS FOR MAN 23/30H Mk3 GENSET

Wednesday, February 10, 2021 

MAN Energy Solutions’ South Korean licensee STX Engine has signed a contract with Daehan shipbuilding for three MAN 6L23/30H Mk3 GenSets, which marks the first sale of the engine’s Mk3 version.

The engines will achieve Tier III emission levels with the aid of SCR. They are provisionally scheduled for delivery in August 2021; the contract includes an option for  a further ship set.

Finn Fjeldhøj, Head of Small-Bore, Four-Stroke Engineering, MAN Energy Solutions, said: “This is an important order; our 23/30H GenSet is a proven workhorse that our customers have much appreciated over the past half-century, and whose new mark now prepares it for the next many years in the market.”

The first 23/30H engine came on the market in 1965 and has a long history of operational stability. The engine's popularity is said to be due to its reliability and ‘forgiving’ service demands. Globally, well over 12,000 units have been produced over its lifetime.

Applications for the engine include tankers, bulk carriers and product tankers as auxiliary engines, with some sales as prime movers for fishing trawlers and power plants. The engine is mostly diesel-driven, with LNG and bio-oil used in special environmental areas.

The new Mk3 variant is a said to be a cost-effective GenSet; it complies with 2020 SOx-regulations and has a power range of 500-1800 kW. Compared with its Mk2 predecessor, among other characteristics, it features:

  • an increased power-output per cylinder
  • a reduced fuel-oil consumption
  • the longest TBO in its class
  • an improved conrod design
  • a two-part piston design for fast maintenance.
