AEGEAN WAVE 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 29,733 gross tonnage it is larger than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it AEGEAN WAVE for 2018–2023 and SEAWAYS CREST for 2024–2025. The reported port of registry changed: Hong Kong (2018–2023), then Majuro (2024–2025).
Its 2,127 t of CO₂ for 2025 is 62% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 250.7 kg CO₂, close to the type median of 250.2 kg. It logged 688 hours at sea against a median of 2,109 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (6,803 t) and the lowest 2025 (2,127 t). Its efficiency percentile within the type went from 13 in 2018 to 35 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 470 of 1,348 qualifying chemical tankers by EEOI, at the 35th percentile. The dashed line is the type median, 14.4; this vessel reported 11.9.
EEOI divides emissions by transport work, which for this vessel and year was 178,556,675 tonne-miles over 8,483 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 7.2% while distance sailed rose 25.5%and CO₂ per nautical mile fell 26.0%.
