GASLOG WALES against its type

Built in 2020, it is 6 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). It is one of 62 LNG carriers here under the Bermuda flag, 11.5% of the 538 on the register. The same builder is recorded for 563 other vessels here, 82 of them LNG carriers. The returns for 2021–2025 all give Hamilton as port of registry.

Its 9,004 t of CO₂ for 2025 is 58% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 491.6 kg CO₂, close to the type median of 533.6 kg. It logged 1,146 hours at sea against a median of 2,940 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 5 years with reported emissions, the highest was 2023 (29,592 t) and the lowest 2025 (9,004 t). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
