GASTONE against its type

Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 43,673 gross tonnage it is larger than 74% of the other 6,571 bulk carriers with a recorded tonnage. 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 196 other vessels here, 94 of them bulk carriers. Its MRV returns name it KMARIN KENAI for 2018–2021 and GASTONE for 2022–2025. The returns for 2021–2025 all give Majuro as port of registry.

Its 3,888 t of CO₂ for 2025 is 20% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 381.0 kg CO₂, 46% above the type median of 260.7 kg. It logged 1,055 hours at sea against a median of 1,200 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2019 (11,458 t) and the lowest 2021 (1,492 t). Its efficiency percentile within the type went from 32 in 2019 to 91 in 2025 (lower is more efficient). Of the 2 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 2,952 of 3,241 qualifying bulk carriers by EEOI, at the 91st percentile. The dashed line is the type median, 7.6; this vessel reported 13.2.

0255075100more efficientless efficientThis vessel: 91st percentile, EEOI 13.2

EEOI divides emissions by transport work, which for this vessel and year was 295,247,532 tonne-miles over 10,205 nautical miles.

Reported CO₂ in 2025 was 66.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions fell 15.6% while distance sailed fell 31.9%and CO₂ per nautical mile rose 24.1%.
