Wärtsilä LNG conversions

Wärtsilä has been contracted by US shipowner Totem Ocean Trailer Express (Totem Ocean) to supply equipment for what is said to be the largest LNG conversions to be undertaken in the US.

The company will provide main engines, generators and LNGPac integrated LNG storage and fuel gas handling systems for conversion of Totem Ocean’s two Orca Class ro-ro cargo ships, Midnight Sun and North Star.

According to Wärtsilä, as a result of the conversion, the Totem Ocean vessels will set new standards for environmental responsibility by reducing SOx emission by 100%, PM by 91%, NOx by 90% and CO2 by 35%.

Björn Rosengren, president & CEO of Wärtsilä Corporation, said:”It is an unprecedentedly exciting time to be in the maritime industry. Economic constraints and the need to comply with environmental legislation have combined to accelerate the switch to LNG fuel.”

Each of the vessels will be equipped with four 12-cylinder Wärtsilä 50DF dual-fuel engines and generator sets that can run on LNG, HFO or MGO, and two 1100 m³ LNGPac fuel storage tanks with associated automaton and fuel gas handling systems.

In addition to the equipment, Wärtsilä is taking responsibility for the design, engineering and integration of the system, and project and site management for its scope of supply.
