SIEM ARISTOTLE against its type
Built in 2020, it is 12 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 72,900 gross tonnage it is larger than 93% of the other 571 vehicle carriers with a recorded tonnage. It is one of 89 vehicle carriers here under the Liberia flag, 12.5% of the 713 on the register. The same builder is recorded for 41 other vessels here, 22 of them vehicle carriers. The returns for 2020–2025 all give Monrovia as port of registry.
Its 14,324 t of CO₂ for 2025 is 2.0 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 259.2 kg CO₂, 16% below the type median of 309.1 kg. It logged 3,776 hours at sea against a median of 1,639 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2025 (14,324 t) and the lowest 2020 (5,046 t). Its efficiency percentile within the type went from 24 in 2020 to 65 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.
