GH MAESTRO against its type

Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 38,364 gross tonnage it is smaller than 58% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Marshall Islands flag, 3.4% of the 3,495 on the register. Its MRV returns name it MARTHA SCHULTE for 2018–2019 and GH MAESTRO for 2020–2024. The reported port of registry changed: Limassol (2018–2019), then Majuro (2020–2024).

Its 21,408 t of CO₂ for 2024 is 20% above the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 484.9 kg CO₂, close to the type median of 528.5 kg. It logged 3,603 hours at sea against a median of 3,325 hours for its type that year. 1.8% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 7 years with reported emissions, the highest was 2021 (22,451 t) and the lowest 2020 (14,185 t). Its efficiency percentile within the type went from 83 in 2018 to 73 in 2024 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.
