CHEMBULK WESTPORT against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 18,760 gross tonnage it is smaller than 57% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. Its MRV returns name it CHEMBULK WESTPORT for 2018 and MTM WESTPORT for 2020–2024. The reported port of registry changed: Majuro (2018), then Singapore (2020–2024).
Its 1,524 t of CO₂ for 2024 is 74% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 216.7 kg CO₂, 15% below the type median of 253.5 kg. It logged 591 hours at sea against a median of 2,177 hours for its type that year. 0.7% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2021 (7,983 t) and the lowest 2024 (1,524 t). Its efficiency percentile within the type went from 63 in 2018 to 4 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 48 of 1,194 qualifying chemical tankers by EEOI, at the 4th percentile. The dashed line is the type median, 15.9; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 212,243,733 tonne-miles over 7,034 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 60.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2022, 2023, so the series has gaps.
From 2021 to 2024, emissions fell 80.9% while distance sailed fell 77.4%and CO₂ per nautical mile fell 15.5%.That points mainly to how much the vessel sailed, rather than the other.
