STX Engine has signed a contract with South Korea’s Daehan Shipbuilding for three MAN 6L23/30H Mk3 gen-sets.

The order marks the first sale of the engine’s Mk3 version gen-set which has a power range of 500 to 1800 kW. Each of the Atlas Maritime sets has an output of 1200 kW.

The engines are bound for an Aframax crude tanker ordered by Atlas Maritime, the Greek international shipping company, and will achieve Tier 3 emission levels with the aid of SCR. They are provisionally scheduled for delivery in August 2021.

The first 23/30H engine came on the market in 1965 and more than 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 also used in special environmental areas.

Finn Fjeldhøj, Head of Small-Bore, Four-Stroke Engineering, MAN Energy Solutions, said: “This is an important order; our 23/30H gen-set 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.”

Compared with its Mk2 predecessor, among other characteristics, it features an increased power-output per cylinder, a reduced fuel-oil consumption, an improved conrod design and a two-part piston design for fast maintenance, according to MAN.
