Wärtsilä bags five-LNG carrier maintenance gig with Greek firm

Wärtsilä Gas Solutions, part of Finland’s technology firm Wärtsilä, has signed an agreement with Greek fleet owner GasLog for the service and maintenance of the latter’s liquefied natural gas (LNG) carriers.

The three-year agreement covers five 180,000 cubic meter LNG carrier vessels, all of which are equipped with Wärtsilä proprietary mixed refrigerant (MR) Reliq liquefaction plants. The signing took place in December 2024, when Wärtsilä booked the order.

The deal encompasses technical support, secured availability of spare parts and specialized field service personnel, and performance monitoring of the Finnish firm’s plants onboard the vessels. Additionally, Wärtsilä will provide remote technical support and operational data monitoring as part of its 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,” noted Saman Siahpoush, Head of Services Sales at Wärtsilä Gas Solutions.

According to Wärtsilä, the boil-off gas (BOG) from the LNG cargo can be efficiently managed by optimizing the operation of the ships’ MR Reliq plants. This is said to reduce emissions and minimize cargo losses, thus improving the vessels’ economic performance.

The Finnish firm’s reliquefaction system was chosen for retrofit and installation onboard a floating storage regasification unit (FSRU) owned by Excelerate Energy in September. The technology is meant to improve the environmental footprint of the vessels’ operations.

Meanwhile, one of GasLog’s LNG carriers, GasLog Savannah, delivered the first LNG shipment from the United States to Ukraine’s DTEK Group at the Revithoussa LNG terminal in Greece last week. The Ukranian player plans to regasify the LNG and send it through the European Union and Ukrainian gas networks.
