MARITIME TRANQUILITY against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 33,355 gross tonnage it is larger than 98% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The returns for 2023–2025 all give Singapore as port of registry.
Its 5,412 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 282.4 kg CO₂, 13% above the type median of 250.2 kg. It logged 2,047 hours at sea against a median of 2,106 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (9,421 t) and the lowest 2021 (1,438 t). Its efficiency percentile within the type went from 68 in 2021 to 8 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 116 of 1,348 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 14.4; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 700,194,049 tonne-miles over 19,170 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 276.4% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 13.5% while distance sailed rose 0.7%and CO₂ per nautical mile fell 14.1%.That points mainly to how efficiently it sailed, rather than the other.
