IVS MERLIN against its type
Built in 2011, it is 4 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 24,020 gross tonnage it is larger than 91% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. The same builder is recorded for 69 other vessels here, 3 of them general cargo ships. Its MRV returns name it STEADY SARAH for 2022, IVS MERLIN for 2023–2024 and MERLIN for 2025. The returns for 2022–2025 all give Majuro as port of registry.
Its 6,311 t of CO₂ for 2025 is 2.2 times 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 233.0 kg CO₂, 1.9 times the type median of 122.2 kg. It logged 1,947 hours at sea against a median of 3,044 hours for its type that year. 4.2% 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 2022 (6,999 t) and the lowest 2024 (5,086 t). Its efficiency percentile within the type went from 17 in 2022 to 24 in 2025 (lower is more efficient). Of the 2 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 118 of 479 qualifying general cargo ships by EEOI, at the 24th percentile. The dashed line is the type median, 29.4; this vessel reported 22.3.
EEOI divides emissions by transport work, which for this vessel and year was 282,478,066 tonne-miles over 27,089 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.8% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 24.1% and CO₂ per nautical mile rose 0.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
