PORTOLA against its type

Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 8,278 gross tonnage it is smaller than 87% 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. Columbia Shipmanagement is linked to 42 vessels on this register. The returns for 2020–2025 all give MAJURO as port of registry.

Its 4,218 t of CO₂ for 2025 is 24% 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 181.5 kg CO₂, 27% below the type median of 250.2 kg. It logged 2,368 hours at sea against a median of 2,109 hours for its type that year. 4.7% 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 (9,106 t) and the lowest 2024 (331 t). Its efficiency percentile within the type went from 81 in 2020 to 91 in 2025 (lower is more efficient). Of the 4 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 1,224 of 1,348 qualifying chemical tankers by EEOI, at the 91st percentile. The dashed line is the type median, 14.4; this vessel reported 37.8.

Across the 41 ranked vessels operated by Columbia Shipmanagement, the median percentile is 53. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 111,530,143 tonne-miles over 23,245 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 3.9% higher than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 1,174.7% and CO₂ per nautical mile fell 37.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
