BAM PROTEUS against its type

Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 20,236 gross tonnage it is larger than 79% 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 96 other vessels here, 38 of them general cargo ships. Its MRV returns name it HA LONG BAY for 2018–2022 and BAM PROTEUS for 2024–2025. The reported port of registry changed: Douglas (2018–2022), then Majuro (2024–2025).

Its 3,559 t of CO₂ for 2025 is 26% above 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 203.8 kg CO₂, 1.7 times the type median of 122.2 kg. It logged 1,584 hours at sea against a median of 3,044 hours for its type that year. 11.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2024 (4,880 t) and the lowest 2022 (2,230 t). Its efficiency percentile within the type went from 4 in 2024 to 5 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 27 of 479 qualifying general cargo ships by EEOI, at the 5th percentile. The dashed line is the type median, 29.4; this vessel reported 11.3.

0255075100more efficientless efficientThis vessel: 5th percentile, EEOI 11.3

EEOI divides emissions by transport work, which for this vessel and year was 314,714,412 tonne-miles over 17,462 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 15.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 27.1% while distance sailed fell 24.3%and CO₂ per nautical mile fell 3.6%.That points mainly to how much the vessel sailed, rather than the other.
