SEA LA BAMBA 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 29,130 gross tonnage it is larger than 67% 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. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it SWIFT WINCHESTER for 2019–2020, UOG HELIOS for 2022 and SEA LA BAMBA for 2023–2025. The reported port of registry changed: Majuro (2022), then MONROVIA (2023–2025).
Its 177 t of CO₂ for 2025 is 97% 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 744.2 kg CO₂, 3.0 times the type median of 250.2 kg. It logged 20 hours at sea against a median of 2,106 hours for its type that year. 61.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2023 (10,295 t) and the lowest 2025 (177 t). Its efficiency percentile within the type went from 66 in 2019 to 16 in 2024 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 194 of 1,194 qualifying chemical tankers by EEOI, at the 16th percentile. The dashed line is the type median, 15.9; this vessel reported 9.3.
EEOI divides emissions by transport work, which for this vessel and year was 498,164,339 tonne-miles over 15,434 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 98.2% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 96.2% and CO₂ per nautical mile rose 147.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
