EMERALD BAY against its type

Built in 2008, it is 1 year newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 20,242 gross tonnage it is larger than 80% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 27 general cargo ships here under the Isle of Man flag, 0.9% of the 3,081 on the register. The same builder is recorded for 96 other vessels here, 38 of them general cargo ships. The returns for 2018–2025 all give Douglas as port of registry.

Its 2,300 t of CO₂ for 2025 is 18% 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 216.7 kg CO₂, 1.8 times the type median of 122.2 kg. It logged 1,002 hours at sea against a median of 3,044 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2021 (7,265 t) and the lowest 2023 (1,879 t). Its efficiency percentile within the type went from 14 in 2021 to 1 in 2024 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 5 of 321 qualifying general cargo ships by EEOI, at the 1st percentile. The dashed line is the type median, 23.6; this vessel reported 6.4.

Reported CO₂ in 2025 was 33.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 11.3% and CO₂ per nautical mile rose 24.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
