Technology group Wärtsilä has signed an eight-year Guaranteed Asset Performance agreement with Japanese operator NYK LNG Ship Management. The agreement covers the two Wärtsilä X72DF main engines on an LNG Carrier vessel and is designed to maximise the vessel availability and ensure its operation from dry dock to dry dock. This is achieved by guaranteeing the maximum time between overhauls. This guarantee ensures the safe and reliable operation between docks and minimises the impact of the maintenance on the vessel availability. The improved availability results in increased vessels earnings with the lowest maintenance cost. Furthermore, the performance guarantee ensures operational efficiency with minimal emissions. The contract was booked as order intake by Wärtsilä in March 2023.
