BOW COMPASS against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 19,440 gross tonnage it is smaller than 57% 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. Thome Ship Management is linked to 42 vessels on this register. The returns for 2018–2025 all give Bergen as port of registry.
Its 5,439 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 253.1 kg CO₂, close to the type median of 250.2 kg. It logged 1,844 hours at sea against a median of 2,106 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2021 (14,190 t) and the lowest 2019 (4,219 t). Its efficiency percentile within the type went from 30 in 2018 to 46 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 626 of 1,348 qualifying chemical tankers by EEOI, at the 46th percentile. The dashed line is the type median, 14.4; this vessel reported 13.8.
Across the 39 ranked vessels operated by Thome Ship Management, the median percentile is 54. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 393,566,570 tonne-miles over 21,494 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 11.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 18.6% while distance sailed fell 18.3%and CO₂ per nautical mile fell 0.3%.That points mainly to how much the vessel sailed, rather than the other.
