GW FORTUNE 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 34,988 gross tonnage it is larger than 98% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 27 chemical tankers here under the Saudi Arabia flag, 1.2% of the 2,344 on the register. Its MRV returns name it GW FORTUNE for 2020–2023 and RAWAN for 2024–2025. The reported port of registry changed: HONG KONG (2023), then DAMMAM (2024–2025).
Its 8,421 t of CO₂ for 2025 is 1.5 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 308.3 kg CO₂, 23% above the type median of 250.2 kg. It logged 2,289 hours at sea against a median of 2,109 hours for its type that year. 7.7% 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 (8,485 t) and the lowest 2020 (1,837 t). Its efficiency percentile within the type went from 13 in 2020 to 25 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 333 of 1,348 qualifying chemical tankers by EEOI, at the 25th percentile. The dashed line is the type median, 14.4; this vessel reported 10.1.
EEOI divides emissions by transport work, which for this vessel and year was 835,413,690 tonne-miles over 27,314 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 358.5% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 321.8% while distance sailed rose 283.9%and CO₂ per nautical mile rose 9.9%.That points mainly to how much the vessel sailed, rather than the other.
