Finnish technology group Wärtsilä has signed a long-term maintenance deal with Japanese LNG shipowner Tokyo LNG Tanker, a Tokyo Gas unit.
Wärtsilä said on Tuesday that the deal entails a range of maintenance needs for three LNG carriers powered by Wärtsilä 50DF dual-fuel engines.
For the duration of the deal, the company will utilize its maintenance solution which covers scheduled maintenance as well as dynamic maintenance planning inspections and spare parts.
The condition-based maintenance provided by Wärtsilä will enable predictive assessments of servicing needs based on actual component performance, rather than conventional time-based scheduling.
This could eliminate the need for unexpected and unscheduled vessel repairs, the company said.
The 165,000-cbm tankers are each powered by four 9-cylinder Wärtsilä 50DF and one 6-cylinder Wärtsilä 50DF engines.
