SM SEOUL 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 41,331 gross tonnage it is smaller than 53% of the other 3,000 container ships with a recorded tonnage. It is one of 11 container ships here under the South Korea flag, 0.3% of the 3,495 on the register. The same builder is recorded for 461 other vessels here, 155 of them container ships. Its MRV returns name it SPIRIT OF HONG KONG for 2023–2024 and SM SEOUL for 2025. The reported port of registry changed: Majuro (2023–2024), then JEJU (2025).
Its 15,069 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 502.2 kg CO₂, close to the type median of 545.6 kg. It logged 2,346 hours at sea against a median of 3,155 hours for its type that year. 0.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2023 (16,513 t) and the lowest 2025 (15,069 t). Its efficiency percentile within the type went from 48 in 2023 to 98 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
