NORDIC AQUARIUS against its type

Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). It is one of 18 oil tankers here under the Cayman Islands flag, 0.5% of the 3,548 on the register. The same builder is recorded for 563 other vessels here, 217 of them oil tankers. The returns for 2018–2025 all give George Town as port of registry.

Its 18,904 t of CO₂ for 2025 is 2.4 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 420.6 kg CO₂, close to the type median of 403.2 kg. It logged 4,014 hours at sea against a median of 2,030 hours for its type that year. 10.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2025 (18,904 t) and the lowest 2020 (7,231 t). Its efficiency percentile within the type went from 12 in 2018 to 34 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 489 of 1,448 qualifying oil tankers by EEOI, at the 34th percentile. The dashed line is the type median, 7.5; this vessel reported 6.3.

EEOI divides emissions by transport work, which for this vessel and year was 3,010,117,834 tonne-miles over 44,941 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 49.6% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 53.1% while distance sailed rose 36.4%and CO₂ per nautical mile rose 12.3%.That points mainly to how much the vessel sailed, rather than the other.
