IRON POINT 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 30,119 gross tonnage it is larger than 93% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it IRON POINT for 2019, PS HOUSTON for 2021 and JOHNNY RANGER for 2022–2025. The reported port of registry changed: Valletta (2019–2021), then Monrovia (2022–2025).
Its 320 t of CO₂ for 2025 is 94% 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 405.2 kg CO₂, 1.6 times the type median of 250.2 kg. It logged 174 hours at sea against a median of 2,106 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (15,610 t) and the lowest 2025 (320 t). Its efficiency percentile within the type went from 92 in 2019 to 12 in 2024 (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 type2024
Position 143 of 1,194 qualifying chemical tankers by EEOI, at the 12th percentile. The dashed line is the type median, 15.9; this vessel reported 8.7.
EEOI divides emissions by transport work, which for this vessel and year was 854,866,359 tonne-miles over 22,984 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 89.3% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 95.7% and CO₂ per nautical mile rose 25.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
