ONE TRITON against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 76,499 gross tonnage it is larger than 67% of the other 3,000 container ships with a recorded tonnage. It is one of 2 container ships here under the Cayman Islands flag, 0.1% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. Columbia Shipmanagement Ltd. is linked to 43 vessels on this register. The returns for 2024–2025 all give George Town as port of registry.
Its 31,542 t of CO₂ for 2025 is 1.9 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 567.5 kg CO₂, close to the type median of 545.6 kg. It logged 4,126 hours at sea against a median of 3,155 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2024 (47,898 t) and the lowest 2023 (31,541 t). Its efficiency percentile within the type went from 36 in 2023 to 47 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 865 of 1,838 qualifying container ships by EEOI, at the 47th percentile. The dashed line is the type median, 14.2; this vessel reported 13.6.
Across the 36 ranked vessels operated by Columbia Shipmanagement Ltd., the median percentile is 66. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 2,320,978,661 tonne-miles over 55,579 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was <0.1% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 34.1% while distance sailed fell 34.5%and CO₂ per nautical mile rose 0.5%.That points mainly to how much the vessel sailed, rather than the other.
