Wärtsilä Signs Five-Year Service Deal for Two LNG Carriers
Wärtsilä will maintain two new 174,000 m³ LNG carriers for TMS Cardiff Gas for five years. The contract value was not disclosed.
Wärtsilä's five-year service deal with TMS Cardiff Gas is a fleet-availability contract, not a market signal. It covers two newbuild 174,000 m³ LNG carriers, Al Thurayya and Al Majhoulah, with no disclosed value. For LNG shipping, the relevant question is uptime of new tonnage, which the sources do not yet measure.

- The deal covers two newbuild 174,000 m³ LNG carriers, Al Thurayya and Al Majhoulah.
- The package combines Dynamic Maintenance Planning, the Expert Insight predictive service, contract management and 24-hour remote support.

Wärtsilä has signed a five-year maintenance and support agreement with TMS Cardiff Gas for two newbuild LNG carriers. Wärtsilä's release is dated 7 October 2026, and Offshore Technology reported it on 8 October. Both say the order was booked in the third quarter of 2026. No value was disclosed. It is a vessel-availability story rather than a price or volume story, and this desk offers analysis, not trading advice.
What the contract covers
The agreement covers Al Thurayya and Al Majhoulah, each of 174,000 m³. Per vessel, Offshore Technology lists two WinGD 5X72DF two-stroke main engines, four Wärtsilä 34DF auxiliary engines and Wärtsilä gas valve units. The services are Dynamic Maintenance Planning, the Expert Insight predictive maintenance solution, contract management and 24-hour remote operational support. Wärtsilä describes the planning service as adjusting maintenance schedules and intervals to operating conditions.
Why carrier availability matters
Tonnage that is available to sail is the point of a service contract, because an LNG carrier in unplanned maintenance cannot lift cargo. TMS Cardiff Gas deputy chief operating officer Alexandros Politis-Kalenteris is quoted by Offshore Technology as saying there is increasing global demand for LNG and carrier operators place a high value on reliability. That is the operator's view of its own priorities. Neither source offers fleet-wide data showing that service contracts change availability.
What the sources do not show
The sources do not disclose a contract value, and they do not link these two ships to a Gulf owner, loading terminal or export contract. Offshore Technology reports Wärtsilä's claim that maintenance planning could allow longer maintenance intervals and lower spare-parts use; that is a supplier claim, and no outcome data from these ships has been published. The deal follows a 2025 renewal covering seven TMS Cardiff Gas LNG carriers, per Offshore Technology, which points to continuity rather than a shift.
What to watch next
The useful evidence would be published availability or maintenance-interval results from these two ships once they have operated for a meaningful period. Until then, treat the efficiency claims as unverified. Readers tracking Gulf gas and LNG should look to cargo, contract and freight-rate data from official and port sources for market conclusions, because this agreement carries no such information and is not a forecast of volumes or rates.
