M.A.N.-B&W Offers Cost-Saving Systems For Their MC Engines —New Brochures Available
With their line of MC engines well-established in the marine industry, M.A.N.-B&W Diesel A/S is now focusing on the continuing expansion of their engine program and its application possibilities, including the use of turbo compound systems, which have kept pace with the increased specialization in the shipbuilding sector.
The current range of M.A.N.- B&W two-stroke engines comprises three variants of long-stroke engines— the K-MC, L-MC and SMC.
As a new feature which will expand opportunities for the application of MC-engines, a special version designated the MC-GI, is now being introduced. The MC-GI engine (GI stands for gas injection) will, through the application of a unique high pressure gas injection technology, enable the use of natural gas and other combustile gases in the engines at outputs and thermal efficiencies identical to those of current heavy fuel burning MC-engines.
This system, which has been demonstrated in operation on a full scale 35MC engine and approved by the classification societies, now represents an economically attractive propulsion alternative for LNG carriers and for stationary power plants.
Realizing that the engine process itself needs only a certain turbocharger efficiency, the high efficiency of the latest versions of the turbochargers (M.A.N. NA/TO and BBC VTR-4A) makes it possible to obtain even lower fuel consumption by utilizing part of the exhaust gas in a Turbo Compound System (TCS).
The TCS comprises a gas turbine which is driven by an exhaust gas by-pass. The turbine can be connected mechanically to the main engine front end, via a gear box. The "surplus" exhaust gas is therefore utilized by by-passing the turbocharger and using it to drive a gas turbine unit, thus producing mechanical energy. The power obtained is fed back to the main engine, thereby reducing the fuel oil consumption at the same output power.
According to the company, when a TCS unit is installed, savings of up to 5 g/bhph can be obtained, and based upon an oil price of $170 per ton, means a savings of approximately $50,000 for every 10,000 bhp per 250 days of operation.
Another cost-saving product offered by M.A.N.-B&W is the PTO—power take-off—which is a generator driven by the main engine via a hydraulic frequency control box (RCF—Renk Constant Frequency) mounted on the side of the main engine for producing electrical power for a ship.
The company maintains that up to $23,000 worth of fuel oil and maintenance can be saved for every 250 days in operation, when a 550- kw PTO unit is used on a 5L70MC engine at 80 percent mcr (based on a fuel oil price of $170 per ton).
M.A.N.-B&W also is offering a system which combines the use of both PTO and TCS called PTO/ PTI.
