MAERSK GUAYAQUIL against its type

Built in 2015, it is 7 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 113,042 gross tonnage it is larger than 82% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 211 other vessels here, 61 of them container ships. The reported port of registry changed: Hong Kong (2018–2024), then Singapore (2025).

Its 66,791 t of CO₂ for 2025 is 4.1 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 712.4 kg CO₂, 31% above the type median of 545.6 kg. It logged 6,059 hours at sea against a median of 3,155 hours for its type that year. 0.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2024 (69,225 t) and the lowest 2021 (4,482 t). Its efficiency percentile within the type went from 12 in 2018 to 26 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 475 of 1,838 qualifying container ships by EEOI, at the 26th percentile. The dashed line is the type median, 14.2; this vessel reported 9.2.

EEOI divides emissions by transport work, which for this vessel and year was 7,244,186,551 tonne-miles over 93,757 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 121.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions fell 3.5% while distance sailed rose 2.0%and CO₂ per nautical mile fell 5.4%.That points mainly to how efficiently it sailed, rather than the other.
