GULF MOON 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 23,656 gross tonnage it is larger than 54% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 30 chemical tankers here under the Bahamas flag, 1.3% 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 GULF MOON for 2018–2019 and MILOU for 2022–2025. The returns for 2018–2025 all give Nassau as port of registry.

Its 4,092 t of CO₂ for 2023 is 24% below the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 298.7 kg CO₂, 16% above the type median of 258.0 kg. It logged 1,153 hours at sea against a median of 1,919 hours for its type that year. 12.1% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 3 years with reported emissions, the highest was 2022 (4,715 t) and the lowest 2019 (2,429 t). Its efficiency percentile within the type went from 35 in 2019 to 30 in 2023 (lower is more efficient).

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2023

Position 374 of 1,230 qualifying chemical tankers by EEOI, at the 30th percentile. The dashed line is the type median, 15.6; this vessel reported 12.3.

EEOI divides emissions by transport work, which for this vessel and year was 331,632,091 tonne-miles over 13,700 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 68.5% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2024, so the series has gaps.

From 2022 to 2023, emissions fell 13.2% while distance sailed fell 8.7%and CO₂ per nautical mile fell 5.0%.That points mainly to how much the vessel sailed, rather than the other.
