MANTA SENA against its type

Built in 2006, it is 1 year older than the median general cargo ship on this register, which was built in 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 27 general cargo ships here under the Isle of Man flag, 0.9% 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 REUNION BAY for 2018–2020 and MANTA SENA for 2023–2025. The reported port of registry changed: DOUGLAS (2018–2020), then MONROVIA (2023–2024), then MONRAVIA (2025).

Its 3,275 t of CO₂ for 2025 is 16% 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 217.4 kg CO₂, 1.8 times the type median of 122.2 kg. It logged 1,471 hours at sea against a median of 3,044 hours for its type that year. 5.9% 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 2019 (6,958 t) and the lowest 2024 (635 t). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023

Position 1 of 103 qualifying other ship typess by EEOI, at the 0th percentile. The dashed line is the type median, 85.0; this vessel reported 7.1.

EEOI divides emissions by transport work, which for this vessel and year was 283,420,168 tonne-miles over 11,623 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 32.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions rose 416.0% and CO₂ per nautical mile fell 2.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
