Wärtsilä Gas Solutions, part of technology group Wärtsilä, has signed a three-year Service & Maintenance Agreement with Greek fleet-owner GasLog LNG Services. The agreement covers five 180,000 m3 LNG Carrier vessels, all of which are fitted with Wärtsilä mixed refrigerant (MR) Reliq liquefaction plants. The signing took place in December 2024, and the order was booked by Wärtsilä in the same month.

By optimising the operation of the ships’ MR Reliq plants, the boil-off gas (BOG) from the LNG cargo can be efficiently managed. This reduces emissions while also minimising cargo losses, thereby improving the vessels’ economic performance.

The scope of the agreement includes technical support, secured availability of spare parts and specialised field service personnel, as well as performance monitoring of the MR Reliq plants. Remote technical support and operational data monitoring is provided by Wärtsilä digital services.

“GasLog is a leading global provider of LNG shipping services, helping the world transition to a lower carbon future. We at Wärtsilä Gas Solutions are excited to support them in this by ensuring the efficient and sustainable operation of their onboard liquefaction plants. We look forward to continuing our long-term partnership and collaboration,” comments Saman Siahpoush, Head of Services Sales, Wärtsilä Gas Solutions.

GasLog LNG Services has long been a customer of Wärtsilä. The company’s fleet operates with a range of Wärtsilä solutions.
