SEAVEN VOYAGER against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 5,031 gross tonnage it is smaller than 100% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 18 chemical tankers here under the Greece flag, 0.8% of the 2,344 on the register. The same builder is recorded for 3 other vessels here, 2 of them chemical tankers. The returns for 2018–2025 all give PIRAEUS as port of registry.
Its 3,525 t of CO₂ for 2025 is 36% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 123.3 kg CO₂, 51% below the type median of 250.2 kg. It logged 3,006 hours at sea against a median of 2,109 hours for its type that year. 22.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (7,112 t) and the lowest 2023 (2,949 t). Its efficiency percentile within the type went from 89 in 2018 to 90 in 2024 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 1,073 of 1,194 qualifying chemical tankers by EEOI, at the 90th percentile. The dashed line is the type median, 15.9; this vessel reported 39.0.
EEOI divides emissions by transport work, which for this vessel and year was 127,592,973 tonne-miles over 35,098 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 29.1% and CO₂ per nautical mile fell 13.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
