STEN TOR against its type

Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 14,000 gross tonnage it is smaller than 63% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 5 chemical tankers here under the Finland flag, 0.2% of the 2,344 on the register. The same builder is recorded for 65 other vessels here, one of them a chemical tanker. Its MRV returns name it STEN TOR for 2018–2019 and UIKKU for 2021–2025. The reported port of registry changed: Bergen (2018–2019), then HELSINKI (2021–2025).

Its 10,977 t of CO₂ for 2025 is 2.0 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 236.9 kg CO₂, close to the type median of 250.2 kg. It logged 4,454 hours at sea against a median of 2,109 hours for its type that year. 14.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2025 (10,977 t) and the lowest 2018 (3,204 t). Its efficiency percentile within the type went from 54 in 2018 to 66 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025

Position 884 of 1,348 qualifying chemical tankers by EEOI, at the 66th percentile. The dashed line is the type median, 14.4; this vessel reported 18.9.

EEOI divides emissions by transport work, which for this vessel and year was 579,847,332 tonne-miles over 46,338 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 242.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions rose 7.9% while distance sailed rose 0.3%and CO₂ per nautical mile rose 7.6%.That points mainly to how efficiently it sailed, rather than the other.
