ULRIKEN against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it ULRIKEN for 2018–2023 and VOYAGER for 2025. The reported port of registry changed: George Town (2018–2021), then BERGEN (2022–2023), then Monrovia (2025).
Its 1,564 t of CO₂ for 2025 is 72% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 259.0 kg CO₂, close to the type median of 250.2 kg. It logged 549 hours at sea against a median of 2,106 hours for its type that year. 10.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2021 (8,212 t) and the lowest 2025 (1,564 t). Its efficiency percentile within the type went from 68 in 2018 to 39 in 2023 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 476 of 1,230 qualifying chemical tankers by EEOI, at the 39th percentile. The dashed line is the type median, 15.6; this vessel reported 13.6.
EEOI divides emissions by transport work, which for this vessel and year was 207,883,738 tonne-miles over 9,464 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 44.6% and CO₂ per nautical mile fell 13.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
