Technology group Wärtsilä and TMS Cardiff Gas have renewed their existing Lifecycle Agreement, covering the 2-stroke main engines onboard seven LNG Carrier vessels, for a further five years. The agreement is designed to ensure the vessels’ maximum operational reliability by enabling flexible maintenance scheduling and optimising time between overhauls (TBO). The renewed order was booked by Wärtsilä in Q3 2025.
LNG carrier operators must navigate regulatory, environmental, and geopolitical challenges, along with intense competition from oversupply. This creates pressure to deliver on time while also remaining adaptable.
“In a competitive market, unplanned downtime is costly. The agreement’s combination of technology, high-quality spare parts delivery and expert support means we can continue to strengthen the operational reliability of these vessels, ensuring we can meet rising global LNG demand and tight delivery schedules,” says Alexandros Politis-Kalenteris, Deputy COO, TMS Cardiff Gas.
The seven vessels each operate with two WinGD 5X72DF dual-fuel two stroke engines and Wärtsilä gas valve units. The scope of the agreement includes Wärtsilä’s Dynamic Maintenance Planning service, which will provide flexible maintenance scheduling with extended maintenance intervals and reduced spare parts consumption, 24/7 remote operational support, as well as contract management. It also includes Expert Insight, Wärtsilä's unique predictive maintenance service that uses real-time vessel data to detect potential issues.
“Maximising uptime while ensuring safety, flexibility and reliability is critical for operators,” comments Stefan Wiik, Vice President, Parts and Field Service, Wärtsilä Marine. “Our advanced digital solutions and lifecycle support empower our customers to achieve operational excellence and maximise the availability of their assets."
TMS Cardiff Gas, established in 2011, is an operator and manager, with a fleet of 20 modern Gas Carriers. TMS Cardiff Gas is part of TMS which manages more than 140 ships across the LNG, LPG, Oil/Chemicals, Dry Bulk and Container sectors.
