BW BOSTON against its type
Built in 2003, it is 11 years older than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 93,844 gross tonnage it is smaller than 91% of the other 377 LNG carriers with a recorded tonnage. It is one of 11 LNG carriers here under the Norway flag, 2.0% of the 538 on the register. The same builder is recorded for 660 other vessels here, 109 of them LNG carriers. The returns for 2018–2023 all give Stavanger as port of registry.
Its 22,152 t of CO₂ for 2023 is close to the median of 22,978 t among the 367 LNG carriers on this register that reported for 2023. Per nautical mile it emitted 826.4 kg CO₂, 27% above the type median of 650.5 kg. It logged 3,720 hours at sea against a median of 2,547 hours for its type that year. 2.4% of its 2023 emissions were at berth; the median for LNG carriers was 2.1%. Across 6 years with reported emissions, the highest was 2022 (22,780 t) and the lowest 2021 (7,736 t). Of the 2 sister ships listed below with a 2023 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2023 was 87.7% higher than in 2018, for EU/EEA voyages only.
From 2022 to 2023, emissions fell 2.8% and CO₂ per nautical mile fell 20.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
