COCONEE RICKMERS against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 141,716 gross tonnage it is larger than 87% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. Its MRV returns name it COCONEE RICKMERS for 2018 and MAERSK ESSEN for 2019–2025. The reported port of registry changed: Singapore (2018), then Kobenhagen (2020–2025).
Its 10,389 t of CO₂ for 2025 is 36% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 761.3 kg CO₂, 40% above the type median of 545.6 kg. It logged 873 hours at sea against a median of 3,155 hours for its type that year. 0.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2020 (25,031 t) and the lowest 2021 (5,718 t). Its efficiency percentile within the type went from 11 in 2018 to 6 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 114 of 1,838 qualifying container ships by EEOI, at the 6th percentile. The dashed line is the type median, 14.2; this vessel reported 6.5.
EEOI divides emissions by transport work, which for this vessel and year was 1,603,225,309 tonne-miles over 13,646 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 61.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 49.3% while distance sailed fell 38.2%and CO₂ per nautical mile fell 18.0%.That points mainly to how much the vessel sailed, rather than the other.
