HMM DUBLIN against its type

Built in 2020, it is 12 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 228,283 gross tonnage it is larger than 98% of the other 3,000 container ships with a recorded tonnage. It is one of 387 container ships here under the Panama flag, 11.1% of the 3,495 on the register. The same builder is recorded for 660 other vessels here, 231 of them container ships. HMM is linked to 13 vessels on this register. The returns for 2020–2022 all give Panama as port of registry.

Its 35,134 t of CO₂ for 2025 is 2.1 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 889.6 kg CO₂, 1.6 times the type median of 545.6 kg. It logged 3,997 hours at sea against a median of 3,155 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2024 (43,533 t) and the lowest 2023 (30,357 t). Its efficiency percentile within the type went from 5 in 2020 to 1 in 2025 (lower is more efficient). Of the 8 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 15 of 1,838 qualifying container ships by EEOI, at the 1st percentile. The dashed line is the type median, 14.2; this vessel reported 5.3.

Across the 13 ranked vessels operated by HMM, the median percentile is 1. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 6,666,745,731 tonne-miles over 39,494 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 19.0% lower than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 19.3% while distance sailed fell 18.4%and CO₂ per nautical mile fell 1.1%.That points mainly to how much the vessel sailed, rather than the other.
