DENSA DERYA 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). It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The same builder is recorded for 8 other vessels here, 3 of them chemical tankers. Its MRV returns name it ST MARSEILLE for 2018–2020, VS SALMA for 2021–2023 and DENSA DERYA for 2024–2025. The reported port of registry changed: Luxembourg (2018–2020), then VALLETTA (2021–2025).
Its 4,985 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 151.6 kg CO₂, 39% below the type median of 250.2 kg. It logged 4,281 hours at sea against a median of 2,106 hours for its type that year. 3.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (7,131 t) and the lowest 2024 (3,667 t). Its efficiency percentile within the type went from 96 in 2018 to 92 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 1,236 of 1,348 qualifying chemical tankers by EEOI, at the 92nd percentile. The dashed line is the type median, 14.4; this vessel reported 38.4.
EEOI divides emissions by transport work, which for this vessel and year was 129,726,776 tonne-miles over 32,879 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 35.9% while distance sailed rose 72.3%and CO₂ per nautical mile fell 21.1%.That points mainly to how much the vessel sailed, rather than the other.
