BISCAY 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 7,244 gross tonnage it is smaller than 91% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. Its MRV returns name it CEVDET A for 2018–2019, RUBINO for 2020–2021 and BISCAY for 2022–2025. The reported port of registry changed: Valletta (2018–2019), then Genova (2020–2021), then AALBORG (2022–2025).

Its 8,982 t of CO₂ for 2025 is 1.6 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 194.9 kg CO₂, 22% below the type median of 250.2 kg. It logged 4,919 hours at sea against a median of 2,106 hours for its type that year. 10.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2022 (9,323 t) and the lowest 2018 (1,934 t). Its efficiency percentile within the type went from 83 in 2020 to 86 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,155 of 1,348 qualifying chemical tankers by EEOI, at the 86th percentile. The dashed line is the type median, 14.4; this vessel reported 31.7.

Reported CO₂ in 2025 was 364.4% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 16.0% while distance sailed rose 12.2%and CO₂ per nautical mile rose 3.5%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: AIS movements in Norwegian waters, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
