STI MIGHTY 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 29,991 gross tonnage it is larger than 88% 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. The same builder is recorded for 77 other vessels here, 27 of them chemical tankers. The reported port of registry changed: Singapore (2020–2022), then Majuro (2025).

Its 5,528 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 248.5 kg CO₂, close to the type median of 250.2 kg. It logged 1,823 hours at sea against a median of 2,106 hours for its type that year. 4.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2022 (6,288 t) and the lowest 2021 (2,680 t). Its efficiency percentile within the type went from 10 in 2020 to 13 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 8.8% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions fell 12.1% while distance sailed fell 7.0%and CO₂ per nautical mile fell 5.5%.
