TUVAQ W. against its type
Built in 2012, it is 2 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 5,422 gross tonnage it is smaller than 97% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 40 other vessels here, 32 of them chemical tankers. The reported port of registry changed: Majuro (2020–2021), then Madeira (2022), then Majuro (2023–2025).
Its 1,665 t of CO₂ for 2025 is 70% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 207.8 kg CO₂, 17% below the type median of 250.2 kg. It logged 811 hours at sea against a median of 2,106 hours for its type that year. 13.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (3,509 t) and the lowest 2022 (1,231 t). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 52.5% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 11.8% and CO₂ per nautical mile rose 22.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
