MAN B&W Holeby's CODAG GenSet Is Said To Save Up To 50 Percent In Electricity Production Costs

MAN B&W Holeby reports savings of 50 percent or more in shipboard electricity production costs are possible from the CODAG (combined diesel and gas) GenSet system developed by company. The concept represents one of the most significant advances ever made in improving the economy and operational flexibility of marine auxiliary power generation plants.

The system neatly blends a power turbine in a tandem arrangement with an auxiliary generating set driven by a heavy fuel-burning diesel engine from Holeby's marketleading type 23 and 28 design portfolios.

The incorporation of the company's patented Integrated Charge Air System (ICS) allows the auxiliary diesel to operate continuously on heavy fuel at all loads from full power down to and including idling.

The power turbine is supplied with surplus exhaust gas bypassed from the main engine's turbocharger( s), and the ICS feeds charge air from the main engine to supplement the auxiliary engine turbocharger's effort.

It is the well-proven ICS which makes it possible for the "free of charge" energy of a turbocompound system to be exploited in a power turbine arranged to contribute the main drive for the CODAG GenSet.

The associated auxiliary diesel engine will normally run near the idling condition, only injecting a minor driving force to the set sufficient to act as a speed governor controlling the frequency of the electrical grid.
