MAN ACHIEVES REMOTE TYPE APPROVAL FOR GENSET ENGINE

MAN ACHIEVES REMOTE TYPE APPROVAL FOR GENSET ENGINE

Thursday, April 1, 2021 

MAN Energy Solutions recently conducted a successful Type Approval Test (TAT) for the new L23/30H Mk3 engine, the test, owing to current Covid-19 restrictions, being executed on-site in Korea by STX and MAN Energy Solutions staff, with the classification team joining proceedings remotely.

Finn Fjeldhøj, Head of Small-Bore, Four-Stroke Engineering, MAN Energy Solutions, said: “TATs are an important step in the entry of every engine to the market. The fact that we could surmount the difficulties posed by the global pandemic with a remote solution to successfully get the engine approved is very pleasing. The experience gathered from this event will prove invaluable in the future.”

Christian Rasmussen, MAN Head of Classification Department, said: “Planning for the event began already in the summer of 2020 as a second wave of the virus hit and travel restrictions began to affect logistics. In response, we initiated a series of meetings with six major classification societies to investigate the possibilities for a remote type-test. Stemming from these, we developed a framework to successfully execute the TAT.”

MAN Energy Solutions has initiated a project with classification society, ABS, to further refine the structure of remote tests. This particular project is expected to conclude during 2021, after which the company expects to have defined an optimal flow for remote TATs.

The new engine has been ordered through STX Engine as part of a contract with Daehan shipbuilding for three MAN 6L23/30H Mk3 GenSets. These engines will achieve Tier III emission levels with the aid of SCR, and are provisionally scheduled for delivery in August 2021.

The first 23/30H engine came on the market in 1965 and has a long history of operational stability. Globally, well over 12,000 units have been produced. Applications include uxiliary engines for tankers, bulk carriers and product tankers, with some sales as prime movers for fishing trawlers and power plants. Most are diesel-fuelled, with LNG and bio-oil used in special environmental areas.

The new Mk3 variant complies with 2020 SOx-regulations and has a power range of 500 - 1800kW. 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.
