AETHER SAIL against its type

Built in 2003, it is 7 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 9,993 gross tonnage it is smaller than 81% 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. Terntank is linked to 9 vessels on this register. The returns for 2018–2022 all give Skagen as port of registry.

Its 10,689 t of CO₂ for 2022 is 1.8 times the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 188.6 kg CO₂, 29% below the type median of 266.3 kg. It logged 5,037 hours at sea against a median of 1,995 hours for its type that year. 9.7% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 5 years with reported emissions, the highest was 2020 (11,599 t) and the lowest 2018 (10,178 t). Its efficiency percentile within the type went from 84 in 2018 to 83 in 2022 (lower is more efficient).

Efficiency against its own type2022

Position 1,104 of 1,334 qualifying chemical tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 15.7; this vessel reported 29.7.

Across the 9 ranked vessels operated by Terntank, the median percentile is 78. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 359,790,643 tonne-miles over 56,692 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 5.0% higher than in 2018, for EU/EEA voyages only.

From 2021 to 2022, emissions fell 1.5% while distance sailed fell 3.7%and CO₂ per nautical mile rose 2.2%.That points mainly to how much the vessel sailed, rather than the other.
