GSL SUSAN 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 42,020 gross tonnage it is smaller than 52% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 983 other vessels here, 86 of them container ships. The returns for 2021–2025 all give MONROVIA as port of registry.

Its 24,106 t of CO₂ for 2025 is 47% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 415.2 kg CO₂, 24% below the type median of 545.6 kg. It logged 5,773 hours at sea against a median of 3,155 hours for its type that year. 4.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2021 (34,336 t) and the lowest 2023 (17,554 t). Its efficiency percentile within the type went from 65 in 2021 to 45 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
