ADRIATIC 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 ADRIATIC WAVE for 2018–2022 and SEAWAYS WAVE for 2024–2025. The reported port of registry changed: Hong Kong (2018–2024), then Majuro (2025).
Its 3,811 t of CO₂ for 2025 is 31% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 285.3 kg CO₂, 14% above the type median of 250.2 kg. It logged 1,237 hours at sea against a median of 2,106 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2022 (6,108 t) and the lowest 2021 (1,679 t). Its efficiency percentile within the type went from 16 in 2018 to 46 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 621 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.
EEOI divides emissions by transport work, which for this vessel and year was 277,198,546 tonne-miles over 13,361 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 72.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 25.8% while distance sailed fell 27.6%and CO₂ per nautical mile rose 2.4%.That points mainly to how much the vessel sailed, rather than the other.
