GC BERYL against its type

Built in 2021, it is 11 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 12,099 gross tonnage it is smaller than 69% 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 52 other vessels here, 48 of them chemical tankers. The reported port of registry changed: Hongkong (2021–2022), then Hong Kong (2024–2025).

Its 5,510 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 158.7 kg CO₂, 37% below the type median of 250.2 kg. It logged 2,956 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 3 years with reported emissions, the highest was 2024 (8,138 t) and the lowest 2022 (1,236 t). Its efficiency percentile within the type went from 40 in 2022 to 27 in 2025 (lower is more efficient). Of the 5 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 365 of 1,348 qualifying chemical tankers by EEOI, at the 27th percentile. The dashed line is the type median, 14.4; this vessel reported 10.5.

EEOI divides emissions by transport work, which for this vessel and year was 524,247,383 tonne-miles over 34,730 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 345.7% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions fell 32.3% while distance sailed fell 30.5%and CO₂ per nautical mile fell 2.6%.That points mainly to how much the vessel sailed, rather than the other.
