STOLT SEQUOIA against its type

Built in 2003, it is 7 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,129 gross tonnage it is smaller than 51% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 25 other vessels here, 20 of them chemical tankers. The returns for 2021–2025 all give Monrovia as port of registry.

Its 9,986 t of CO₂ for 2025 is 1.8 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 380.0 kg CO₂, 1.5 times the type median of 250.2 kg. It logged 2,083 hours at sea against a median of 2,109 hours for its type that year. 7.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (10,733 t) and the lowest 2020 (2,149 t). Its efficiency percentile within the type went from 68 in 2018 to 55 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 741 of 1,348 qualifying chemical tankers by EEOI, at the 55th percentile. The dashed line is the type median, 14.4; this vessel reported 15.5.

Reported CO₂ in 2025 was 0.4% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 31.8% while distance sailed rose 22.8%and CO₂ per nautical mile rose 7.3%.That points mainly to how much the vessel sailed, rather than the other.

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