Singapore-based Keppel Shipyard has secured a contract from Totem Ocean Trailer Express to convert a ro-ro vessel into a LNG powered dual-fuel vessel.
Midnight Sun will be the first of US-based Totem Ocean’s two 839 ft Orca-class ro-ro vessels to be converted into a dual-fuel vessel. The conversion is scheduled to start in December 2015 and completed in 90 days, followed by the conversion of North Star, Midnight Sun’s the sister ship.
Upon conversion, the vessels will be equipped with four 12-cylinder Wärtsilä 50DF dual-fuel engines and generator sets. The Wärtsilä 50DF engines have been designed to offer high output, fuel flexibility, low emissions, efficiency, and reliability. They can be run either on natural gas, or light and heavy fuel oil.

The vessels will also have two 1,100 m³ LNG fuel storage tanks and associated automation and fuel gas handling systems.
The conversions are expected to reduce the emission of particulate matter by 91%, sulphur oxides by 90%, and carbon dioxide by 35%, and completely eliminate the emission of nitrogen oxide.
