ALDEN 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 12,138 gross tonnage it is smaller than 67% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 95 chemical tankers here under the Norway flag, 4.1% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. Fleet Management Limited is linked to 40 vessels on this register. Its MRV returns name it TRF KOBE for 2018–2023 and ALDEN for 2024. The reported port of registry changed: Majuro (2018–2023), then Bergen (2024).
Its 5,227 t of CO₂ for 2024 is 10% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 215.1 kg CO₂, 15% below the type median of 253.5 kg. It logged 2,053 hours at sea against a median of 2,177 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2018 (5,774 t) and the lowest 2023 (1,352 t). Its efficiency percentile within the type went from 42 in 2018 to 31 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 385 of 1,230 qualifying chemical tankers by EEOI, at the 31st percentile. The dashed line is the type median, 15.6; this vessel reported 12.4.
Across the 24 ranked vessels operated by Fleet Management Limited, the median percentile is 38. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 108,830,918 tonne-miles over 7,128 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 9.5% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 286.7% and CO₂ per nautical mile rose 13.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
