DSM HARBOUR against its type
Built in 2004, it is 8 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 19,829 gross tonnage it is smaller than 91% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 127 bulk carriers here under the Barbados flag, 1.6% of the 8,138 on the register. The same builder is recorded for 468 other vessels here, 362 of them bulk carriers. Its MRV returns name it OTAGO HARBOUR for 2020–2023 and DSM HARBOUR for 2024–2025. The reported port of registry changed: Hong Kong, China (2020–2023), then Bridgetown (2024–2025).
Its 1,054 t of CO₂ for 2025 is 67% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 233.1 kg CO₂, 11% below the type median of 260.7 kg. It logged 545 hours at sea against a median of 1,200 hours for its type that year. 8.3% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2021 (5,568 t) and the lowest 2025 (1,054 t). Its efficiency percentile within the type went from 60 in 2020 to 44 in 2023 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 69.1% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2025, emissions fell 35.5% and CO₂ per nautical mile rose 18.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
