SILVER HESSA 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 29,375 gross tonnage it is larger than 72% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. The returns for 2018–2025 all give Hong Kong as port of registry.
Its 2,132 t of CO₂ for 2021 is 65% below the median of 6,071 t among the 1,418 chemical tankers on this register that reported for 2021. Per nautical mile it emitted 248.0 kg CO₂, close to the type median of 262.7 kg. It logged 691 hours at sea against a median of 2,112 hours for its type that year. 15.0% of its 2021 emissions were at berth; the median for chemical tankers was 8.4%. Across 4 years with reported emissions, the highest was 2018 (4,324 t) and the lowest 2019 (1,983 t). Its efficiency percentile within the type went from 3 in 2018 to 14 in 2021 (lower is more efficient).
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2021
Position 180 of 1,261 qualifying chemical tankers by EEOI, at the 14th percentile. The dashed line is the type median, 16.1; this vessel reported 10.0.
EEOI divides emissions by transport work, which for this vessel and year was 212,751,497 tonne-miles over 8,595 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 50.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2020 to 2021, emissions fell 0.8% while distance sailed fell 1.0%and CO₂ per nautical mile rose 0.2%.That points mainly to how much the vessel sailed, rather than the other.
