MSC DARIEN against its type
Built in 2003, it is 5 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 89,097 gross tonnage it is larger than 69% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 563 other vessels here, 243 of them container ships. Anglo-Eastern Ship Management is linked to 133 vessels on this register. Its MRV returns name it SEAMAX DARIEN for 2018–2021 and MSC DARIEN for 2022–2025. The reported port of registry changed: Hong Kong (2018–2019), then MAJURO (2020–2021), then Madeira (2022–2025).
Its 45,009 t of CO₂ for 2025 is 2.8 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 757.3 kg CO₂, 39% above the type median of 545.6 kg. It logged 4,402 hours at sea against a median of 3,155 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2021 (74,154 t) and the lowest 2020 (5,446 t). Its efficiency percentile within the type went from 34 in 2018 to 50 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 910 of 1,838 qualifying container ships by EEOI, at the 50th percentile. The dashed line is the type median, 14.2; this vessel reported 14.2.
Across the 102 ranked vessels operated by Anglo-Eastern Ship Management, the median percentile is 55. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 3,171,869,626 tonne-miles over 59,432 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 111.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 51.5% while distance sailed rose 63.3%and CO₂ per nautical mile fell 7.3%.That points mainly to how much the vessel sailed, rather than the other.
