At 19,808 gross tonnage it is larger than 77% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it SN HARMONY for 2022 and SN OPAL for 2023. The returns for 2022–2023 all give JEJU as port of registry.
Its 4,731 t of CO₂ for 2023 is 30% above the median of 3,650 t among the 1,342 general cargo ships on this register that reported for 2023. Per nautical mile it emitted 218.4 kg CO₂, 13% above the type median of 193.7 kg. It logged 2,194 hours at sea against a median of 1,942 hours for its type that year. 8.1% of its 2023 emissions were at berth; the median for general cargo ships was 4.5%. The one comparable vessel listed below with a 2023 return reported a lower CO₂ per nautical mile.
