Wärtsilä has signed a five year maintenance agreement with Finnish ship owner, Viking Line. The agreement is for maintaining and servicing the recently launched ‘Viking Grace’, the largest passenger ferry ever to operate on liquefied natural gas (LNG) fuel.
The arrangement covers the four Wärtsilä 50DF dual-fuel main engines, as well as the Wärtsilä LNGPac gas system’s safety valves. Under the terms of the contract, Wärtsilä will provide a broad range of services including engine maintenance planning, maintenance work, condition monitoring, spare parts supply, technical support, and workshop services. The overall target is to extend the intervals between maintenance, to optimize the logistics for spare part deliveries, and to ensure optimal operating efficiency and fuel consumption, thereby lowering operating costs.
The ‘Viking Grace’ operates a regular timetable schedule in the Baltic Sea between Turku in Finland and Stockholm, Sweden. It is designed to carry cars, trucks and road trailers, as well as 2,800 passengers and 200 crew members. By operating on LNG fuelled Wärtsilä DF engines, the vessel can sail without restrictions in Sulphur Emissions Control Areas (SECAs) and upcoming Nitrogen Emissions Control Areas (NECAs).
With Wärtsilä’s dual-fuel technology, the ‘Viking Grace’ succeeds in meeting the most stringent current and anticipated IMO and EU environmental regulations for maritime applications.
