Stena AB has confirmed that it will shortly convert a second main engine on its ferry Stena Germanica to methanol propulsion after running the one engine for about 700 hours on methanol. All four engines will eventually have four main engines running on methanol by early next year on her route between Gothenburg and Kiel.
Stena said that preparations for the conversion took place when the vessel was in drydock at Remontowa shipyard in March this year so the new conversions are expected to be a lot quicker than for the first engine. The second engine is due to be converted during December and the remaining two by early next year.
The timetable for the engine conversions has been devised so as not to jeopardise the vessel’s operation and to minimise delays.
Methanol requires about double the volume compared to marine diesel oil in order to achieve the same output but the environmental profile is similar to LNG but with less challenging infrastructure. Stena has partnered with Wärtsilä in the conversion project.
Stena has no further methanol conversions planned as yet. A spokesman said: “First we will let Stena Germanica be fully completed and sail for six to 12 months. After that we would like to convert more vessels.”
