BLUE MARLIN against its type
Built in 2000, it is 9 years older than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 51,821 gross tonnage it is larger than 99% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 13 vessels in the other ship types category here under the Malta flag, 2.6% of the 499 on the register. The same builder is recorded for 80 other vessels here, 4 of them vessels in the other ship types category. Royal Boskalis is linked to 4 vessels on this register. The returns for 2018–2025 all give Valletta as port of registry.
Its 2,641 t of CO₂ for 2025 is 48% below the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 1,260.0 kg CO₂, 5.5 times the type median of 231.1 kg. It logged 267 hours at sea against a median of 2,231 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 5 years with reported emissions, the highest was 2024 (39,797 t) and the lowest 2025 (2,641 t). Its efficiency percentile within the type went from 43 in 2019 to 57 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 89 of 155 qualifying other ship typess by EEOI, at the 57th percentile. The dashed line is the type median, 38.0; this vessel reported 47.3.
EEOI divides emissions by transport work, which for this vessel and year was 841,914,745 tonne-miles over 64,193 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 91.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 93.4% and CO₂ per nautical mile rose 103.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
