SEA NEPTUNE against its type
Built in 2013, it is 1 year newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 44,047 gross tonnage it is larger than 76% 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 41 other vessels here, 5 of them bulk carriers. V-Ships is linked to 16 vessels on this register. Its MRV returns name it SEA NEPTUNE for 2018–2020 and SSI SURPRISE for 2022–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 1,237 t of CO₂ for 2025 is 62% 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 300.8 kg CO₂, 15% above the type median of 260.7 kg. It logged 339 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 5 years with reported emissions, the highest was 2022 (12,705 t) and the lowest 2025 (1,237 t). Its efficiency percentile within the type went from 6 in 2018 to 4 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 141 of 3,241 qualifying bulk carriers by EEOI, at the 4th percentile. The dashed line is the type median, 7.6; this vessel reported 3.8.
Across the 14 ranked vessels operated by V-Ships, the median percentile is 59. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 326,306,069 tonne-miles over 4,111 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 67.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 90.3% while distance sailed fell 89.9%and CO₂ per nautical mile fell 3.2%.That points mainly to how much the vessel sailed, rather than the other.
