IRVINE BAY against its type
Built in 2014, it is 7 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,268 gross tonnage it is larger than 88% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 51 general cargo ships here under the Singapore flag, 1.7% of the 3,081 on the register. The same builder is recorded for 323 other vessels here, 25 of them general cargo ships. Its MRV returns name it NEREUS ISLAND for 2018 and IRVINE BAY for 2022–2025. The reported port of registry changed: PANAMA (2018), then Hong Kong, China (2022–2024), then Singapore (2025).
Its 988 t of CO₂ for 2025 is 65% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 176.7 kg CO₂, 45% above the type median of 122.2 kg. It logged 505 hours at sea against a median of 3,044 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2024 (5,456 t) and the lowest 2025 (988 t). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018
Position 830 of 3,151 qualifying bulk carriers by EEOI, at the 26th percentile. The dashed line is the type median, 8.2; this vessel reported 6.5.
EEOI divides emissions by transport work, which for this vessel and year was 562,483,129 tonne-miles over 18,183 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 73.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 81.9% and CO₂ per nautical mile fell 9.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
