Leading solutions and services provider Wärtsilä has signed a five year maintenance agreement with Finnish ship owner, Viking Line. The agreement, which became effective from March 1, is for maintaining and servicing the recently launched 'Viking Grace' [pictured], the largest passenger ferry ever to operate on liquefied natural gas (LNG) fuel.

The agreement 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.

"Viking Line has enjoyed an excellent relationship with Wärtsilä, and this has led to deep cooperation between both parties in finalising this agreement. The maintenance agreement provides predictability in maintenance issues, and through extending maintenance intervals, we can lower operating costs and optimize the lifecycle efficiency of Viking Grace," said Tony Öhman, Senior Vice President, Marine Operations & Newbuilding, Viking Line Abp.

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).

Thanks to Wärtsilä's dual-fuel technology, the Viking Grace meets and even exceeds the most stringent current and anticipated IMO and EU environmental regulations for maritime applications.

Wärtsilä Services is one of three Wärtsilä businesses alongside Ship Power and Power Plants. Wärtsilä Services offers services to both the global marine and energy markets. The company's broad portfolio includes environmental services and solutions, the servicing of engines, propulsion systems, electrical and automation systems, and boilers, as well as field services and spare parts. It also covers upgrades and conversions, long-term agreements for engine and propulsion systems, as well as training services. Wärtsilä Services oprerates some 70 fully owned workshops and employs more than 11,000 service professionals.
