The MAN dual-fuel generating sets L23/30DF and L28/32DF are based on the proven classic GenSet designs L28/32H and L23/30H, recognised worldwide as ultra-reliable and robust GenSets with long TBOs. MAN dual-fuel GenSets also offer low operational and maintenance costs. It is ready for newbuildings and retrofit solutions. The properties of the gas valve regulator, which is installed on the engine, allows a flexible engine room layout. The GVU can be installed at a distance of up to 100 metres from the engine. MAN Energy Solutions’ dedicated engine-diagnostics system – CoCoS-EDS – offers owners and operators an integrated system for data analysis, troubleshooting , trend analysis and online service. The online service makes the know-how of MAN experts available in real time.

A 12-page paper, based on customer feedback: CP Ships (UK) Limited has achieved a very promising 24,000 hours operating interval with MAN B&W Holeby L28/32H GenSets, and the owner is now heading for 30,000 hours before the main overhaul.

When the required vessel power profile has been evaluated and determined, both with regard to propulsion load and electrical load, the next step is to design the engine room configuration so that it will also be optimal with regard to installation, operation and maintenance. MAN B&W Holeby has not only looked at this as an isolated case for the L16/24 type auxiliary engines but, as described in the following, has also looked at it in relation to the MAN B&W twostroke main engine on board.
