ALSEA BAY against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 983 other vessels here, 103 of them bulk carriers. Its MRV returns name it ALSEA BAY for 2018–2020 and BETTY for 2021–2025. The reported port of registry changed: Douglas (2019–2020), then Majuro (2021–2025).
Its 164 t of CO₂ for 2025 is 95% below the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 1,670.0 kg CO₂, 6.4 times the type median of 260.7 kg. It logged 20 hours at sea against a median of 1,199 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2019 (5,581 t) and the lowest 2025 (164 t). Its efficiency percentile within the type went from 31 in 2018 to 49 in 2024 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 1,396 of 2,858 qualifying bulk carriers by EEOI, at the 49th percentile. The dashed line is the type median, 7.9; this vessel reported 7.8.
EEOI divides emissions by transport work, which for this vessel and year was 513,797,176 tonne-miles over 21,066 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 95.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 95.9% and CO₂ per nautical mile rose 779.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
