Finnish engine manufacturer Wärtsilä reports today three new escort tugs under construction for Norwegian tug operator Østensjø Rederi will feature their company’s dual-fuel (DF) engines integrated with a customized gas storage and supply system.

The tugs have been designed by Vancouver-based naval architecture firm Robert Allan Ltd and feature two 6-cylinder Wärtsilä 34DF dual-fuel engines which will enable up to 100 tons of bollard pull capacity as well as Wärtsilä’s unique LNGPac fuel system – a fully integrated gas handling system and the Wärtsilä Gas Valve Unit (GVU).

“These are trend setting tugs in that they provide environmental sustainability through the use of LNG fuel,” says Mr Carl Johan Amundsen, Project Manager at Østensjø Rederi.

The order for the tugs comes on the back of a 15-year contract that Østensjø Rederi signed with Statoil last year to support operations at the Melkøya terminal near Hammerfest, Norway.  The contract commences in early 2017.

The shipyard has not been chosen yet, according to Wärtsilä.
