BRITISH SAILOR against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,948 gross tonnage it is larger than 97% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it BRITISH SAILOR for 2018–2024 and PANTHERLIGHT for 2025. The reported port of registry changed: Douglas (2018–2024), then Valletta (2025).
Its 9,054 t of CO₂ for 2025 is 1.6 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 307.3 kg CO₂, 23% above the type median of 250.2 kg. It logged 2,576 hours at sea against a median of 2,106 hours for its type that year. 6.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (9,054 t) and the lowest 2024 (4,288 t). Its efficiency percentile within the type went from 9 in 2018 to 28 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 384 of 1,348 qualifying chemical tankers by EEOI, at the 28th percentile. The dashed line is the type median, 14.4; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 846,138,318 tonne-miles over 29,458 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 111.1% while distance sailed rose 80.4%and CO₂ per nautical mile rose 17.0%.That points mainly to how much the vessel sailed, rather than the other.
