OCEAN GLADIATOR against its type

Built in 2010, it is 3 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 15,549 gross tonnage it is larger than 73% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 2 general cargo ships here under the United States flag, 0.1% of the 3,081 on the register. The same builder is recorded for 95 other vessels here, 17 of them general cargo ships. Its MRV returns name it ZEA GULF for 2019 and OCEAN GLADIATOR for 2021–2025. The reported port of registry changed: Majuro (2019), then New Orleans (2021), then NEW ORLEANS LA (2022–2025).

Its 1,728 t of CO₂ for 2025 is 39% below 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 312.9 kg CO₂, 2.6 times the type median of 122.2 kg. It logged 416 hours at sea against a median of 3,044 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2019 (7,902 t) and the lowest 2025 (1,728 t). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2019

Position 361 of 381 qualifying general cargo ships by EEOI, at the 95th percentile. The dashed line is the type median, 28.8; this vessel reported 110.0.

0255075100more efficientless efficientThis vessel: 95th percentile, EEOI 110.0

EEOI divides emissions by transport work, which for this vessel and year was 71,813,522 tonne-miles over 23,542 nautical miles.

Reported CO₂ in 2025 was 78.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 68.3% and CO₂ per nautical mile rose 15.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
