RUI FU SHENG against its type

Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,597 gross tonnage it is larger than 77% 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 196 other vessels here, 7 of them chemical tankers. Its MRV returns name it MR SIRIUS for 2018, ATLANTICA BREEZE for 2020–2021 and RUI FU SHENG for 2023–2025. The reported port of registry changed: Majuro (2018), then Monrovia (2020–2025).

Its 3,849 t of CO₂ for 2025 is 30% 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 286.7 kg CO₂, 15% above the type median of 250.2 kg. It logged 1,197 hours at sea against a median of 2,106 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (6,941 t) and the lowest 2018 (3,172 t). Its efficiency percentile within the type went from 40 in 2018 to 16 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 218 of 1,348 qualifying chemical tankers by EEOI, at the 16th percentile. The dashed line is the type median, 14.4; this vessel reported 8.8.

0255075100more efficientless efficientThis vessel: 16th percentile, EEOI 8.8

EEOI divides emissions by transport work, which for this vessel and year was 439,892,571 tonne-miles over 13,426 nautical miles.

Reported CO₂ in 2025 was 21.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2022, so the series has gaps.

From 2024 to 2025, emissions rose 8.3% and CO₂ per nautical mile fell 30.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
