BERNICE against its type
Built in 2001, it is 9 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,063 gross tonnage it is larger than 58% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 30 chemical tankers here under the Bahamas flag, 1.3% 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 VALLE DI CASTIGLIA for 2018–2019, GINZA for 2022 and BERNICE for 2024–2025. The reported port of registry changed: Trieste (2019), then MONROVIA (2022), then Nassau (2024–2025).
Its 6,651 t of CO₂ for 2025 is 20% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 336.1 kg CO₂, 34% above the type median of 250.2 kg. It logged 1,940 hours at sea against a median of 2,106 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2018 (14,711 t) and the lowest 2022 (3,506 t). Its efficiency percentile within the type went from 79 in 2022 to 50 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 673 of 1,348 qualifying chemical tankers by EEOI, at the 50th percentile. The dashed line is the type median, 14.4; this vessel reported 14.4.
EEOI divides emissions by transport work, which for this vessel and year was 461,908,333 tonne-miles over 19,789 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 54.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 33.0% while distance sailed rose 51.6%and CO₂ per nautical mile fell 12.3%.That points mainly to how much the vessel sailed, rather than the other.
