KATTEGAT against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 7,311 gross tonnage it is smaller than 90% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. Its MRV returns name it SAPPHIRE-T for 2018 and KATTEGAT for 2020–2025. The reported port of registry changed: Panama (2018), then AALBORG (2020–2025).

Its 8,246 t of CO₂ for 2025 is 49% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 199.4 kg CO₂, 20% below the type median of 250.2 kg. It logged 4,323 hours at sea against a median of 2,106 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (8,858 t) and the lowest 2022 (7,516 t). Its efficiency percentile within the type went from 80 in 2020 to 85 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,147 of 1,348 qualifying chemical tankers by EEOI, at the 85th percentile. The dashed line is the type median, 14.4; this vessel reported 31.0.

EEOI divides emissions by transport work, which for this vessel and year was 266,094,869 tonne-miles over 41,356 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 6.9% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.

From 2024 to 2025, emissions fell 0.5% while distance sailed fell 6.6%and CO₂ per nautical mile rose 6.5%.
