MAN B&W ME-C series for LNG Carriers. Conclusion
The benefit of diesel engine propulsion of LNG carriers is calculated to be up to approx. US$ 3.0 million per vessel per year. Especially the LNG selling price has a positive impact on the advantage of diesel engine propulsion. The benefit gained in operating costs and the additional income from the sale of LNG by diesel engine propulsion and reliquefaction will, in all cases, be sufficient to justify even large differences in investment costs, if such are called for at all.
Basically, diesel propulsion offers a CO2 emission reduction of about 30% compared to the steam plant.
