BOCHEM BUCEPHALAS against its type
It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. Its MRV returns name it TIGER TENACITY for 2018–2019 and BOCHEM BUCEPHALAS for 2023–2025. The returns for 2018–2025 all give Hong Kong as port of registry.
Its 8,931 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 216.1 kg CO₂, 14% below the type median of 250.2 kg. It logged 3,693 hours at sea against a median of 2,106 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2025 (8,931 t) and the lowest 2019 (3,294 t). Its efficiency percentile within the type went from 65 in 2018 to 36 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 479 of 1,348 qualifying chemical tankers by EEOI, at the 36th percentile. The dashed line is the type median, 14.4; this vessel reported 12.0.
EEOI divides emissions by transport work, which for this vessel and year was 744,854,045 tonne-miles over 41,329 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 46.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 1.5% while distance sailed fell 4.0%and CO₂ per nautical mile rose 5.7%.
