Wärtsilä signs five-year service deal for LNG carriers Al Thurayya and Al Majhoulah
The agreement covers two newly delivered 174,000 cbm ships with WinGD 5X72DF main engines and Wärtsilä 34DF auxiliaries
Wärtsilä has signed a five-year service agreement with Greece-based TMS Cardiff Gas covering two newbuild LNG carriers, the 174,000 cbm Al Thurayya and Al Majhoulah. The order was booked by Wärtsilä in the third quarter of 2026.
The two ships recently entered service as part of a fleet expansion programme at TMS Cardiff Gas. The operator belongs to TMS, which manages more than 140 vessels across the LNG, LPG, oil tanker, dry bulk and container segments.
Each vessel is fitted with two WinGD 5X72DF two-stroke main engines, four Wärtsilä 34DF auxiliary engines and Wärtsilä gas valve units. Under the agreement the ships will be maintained through Wärtsilä's Dynamic Maintenance Planning service, which sets flexible maintenance schedules, extends maintenance intervals and is intended to reduce spare parts consumption. The deal also includes round-the-clock remote operational support, contract management and Expert Insight, Wärtsilä's predictive maintenance service, which uses real-time operating data to identify faults before they develop. The terms are set out in Wärtsilä's release.
The contract extends an existing relationship. In 2025 the two companies renewed an agreement covering seven other vessels in the TMS Cardiff Gas fleet, and the operator already uses Wärtsilä's Fleet Optimisation Solution, which combines voyage planning, performance analytics and compliance management, across its wider fleet.
"The existing agreement covering other vessels in our fleet has delivered a successful combination of technology, high-quality spare parts support and expert services, helping us maintain reliable and efficient operations," said Alexandros Politis-Kalenteris, deputy chief operating officer of TMS Cardiff Gas. He said extending the arrangement to the two newbuilds supported the company's goal of maximising availability across the fleet.
Henrik Wilhelms, director of agreement sales at Wärtsilä Marine, said operators were "looking for greater predictability, efficiency and support throughout the asset lifecycle" as vessel operations become more complex.
