BOLTEN SINGAPORE against its type
Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 36,518 gross tonnage it is larger than 58% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 157 bulk carriers here under the Portugal flag, 1.9% of the 8,138 on the register. The same builder is recorded for 118 other vessels here, 105 of them bulk carriers. Its MRV returns name it KMARIN SINGAPORE for 2018–2022 and BOLTEN SINGAPORE for 2023–2024. The returns for 2023–2024 all give Madeira as port of registry.
Its 5,732 t of CO₂ for 2024 is 1.7 times the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 314.5 kg CO₂, 19% above the type median of 264.0 kg. It logged 1,977 hours at sea against a median of 1,238 hours for its type that year. 6.9% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 3 years with reported emissions, the highest was 2023 (6,548 t) and the lowest 2022 (999 t). Its efficiency percentile within the type went from 71 in 2022 to 66 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 1,894 of 2,858 qualifying bulk carriers by EEOI, at the 66th percentile. The dashed line is the type median, 7.9; this vessel reported 9.3.
EEOI divides emissions by transport work, which for this vessel and year was 618,994,600 tonne-miles over 18,224 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 473.7% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2023 to 2024, emissions fell 12.5% while distance sailed fell 12.8%and CO₂ per nautical mile rose 0.4%.That points mainly to how much the vessel sailed, rather than the other.
