CHEMBULK SAVANNAH against its type
Built in 2002, it is 8 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 15,148 gross tonnage it is smaller than 62% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 7 chemical tankers here under the Barbados flag, 0.3% 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 SAVANNAH for 2018 and WAN HE for 2024–2025. The returns for 2024–2025 all give Bridgetown as port of registry.
Its 4,102 t of CO₂ for 2025 is 26% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 223.0 kg CO₂, 11% below the type median of 250.2 kg. It logged 1,570 hours at sea against a median of 2,109 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2018 (11,434 t) and the lowest 2025 (4,102 t). Its efficiency percentile within the type went from 74 in 2018 to 69 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 925 of 1,348 qualifying chemical tankers by EEOI, at the 69th percentile. The dashed line is the type median, 14.4; this vessel reported 20.2.
EEOI divides emissions by transport work, which for this vessel and year was 203,379,276 tonne-miles over 18,398 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 64.1% lower 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 fell 44.6% while distance sailed fell 38.0%and CO₂ per nautical mile fell 10.5%.That points mainly to how much the vessel sailed, rather than the other.
