OCEAN PRINCESS I 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 30,075 gross tonnage it is larger than 92% 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. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. The returns for 2018–2025 all give Majuro as port of registry.
Its 11,210 t of CO₂ for 2025 is 2.0 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 297.1 kg CO₂, 19% above the type median of 250.2 kg. It logged 3,576 hours at sea against a median of 2,109 hours for its type that year. 9.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2025 (11,210 t) and the lowest 2018 (2,279 t). Its efficiency percentile within the type went from 2 in 2018 to 21 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 282 of 1,348 qualifying chemical tankers by EEOI, at the 21st percentile. The dashed line is the type median, 14.4; this vessel reported 9.3.
EEOI divides emissions by transport work, which for this vessel and year was 1,210,535,637 tonne-miles over 37,729 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 391.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 59.1% while distance sailed rose 88.6%and CO₂ per nautical mile fell 15.6%.That points mainly to how much the vessel sailed, rather than the other.
