NO.5 OCEAN PIONEER 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 11,623 gross tonnage it is smaller than 76% 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 SONGA CHALLENGE for 2018–2023 and NO.5 OCEAN PIONEER for 2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 2,759 t of CO₂ for 2025 is 50% 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 226.1 kg CO₂, close to the type median of 250.2 kg. It logged 1,048 hours at sea against a median of 2,106 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2019 (17,539 t) and the lowest 2020 (1,217 t). Its efficiency percentile within the type went from 41 in 2018 to 39 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 527 of 1,348 qualifying chemical tankers by EEOI, at the 39th percentile. The dashed line is the type median, 14.4; this vessel reported 12.5.
EEOI divides emissions by transport work, which for this vessel and year was 220,891,914 tonne-miles over 12,201 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 33.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 71.4% while distance sailed fell 71.7%and CO₂ per nautical mile rose 1.1%.That points mainly to how much the vessel sailed, rather than the other.
