RUDOLF SAMOYLOVICH against its type
Built in 2017, it is 3 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 128,806 gross tonnage it is larger than 83% of the other 377 LNG carriers with a recorded tonnage. It is one of 63 LNG carriers here under the Bahamas flag, 11.7% of the 538 on the register. The same builder is recorded for 660 other vessels here, 109 of them LNG carriers. The returns for 2018–2025 all give Nassau as port of registry.
Its 65,545 t of CO₂ for 2025 is 3.0 times the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 846.7 kg CO₂, 1.6 times the type median of 533.6 kg. It logged 4,969 hours at sea against a median of 2,940 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 8 years with reported emissions, the highest was 2023 (80,330 t) and the lowest 2018 (9,973 t). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 557.2% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 11.5% and CO₂ per nautical mile fell 10.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
