STAV POWER against its type

At 9,910 gross tonnage it is smaller than 82% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The same builder is recorded for 22 other vessels here. Its MRV returns name it SUULA for 2018–2024 and STAV POWER for 2025. The reported port of registry changed: Porvoo (2018–2022), then Arendal (2023–2024), then MADEIRA (2025).

Its 7,636 t of CO₂ for 2025 is 38% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 241.6 kg CO₂, close to the type median of 250.2 kg. It logged 3,242 hours at sea against a median of 2,109 hours for its type that year. 3.8% 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 (13,014 t) and the lowest 2025 (7,636 t). Its efficiency percentile within the type went from 90 in 2018 to 88 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,184 of 1,348 qualifying chemical tankers by EEOI, at the 88th percentile. The dashed line is the type median, 14.4; this vessel reported 34.2.

EEOI divides emissions by transport work, which for this vessel and year was 223,131,210 tonne-miles over 31,605 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 41.3% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 34.7% while distance sailed fell 37.2%and CO₂ per nautical mile rose 4.0%.That points mainly to how much the vessel sailed, rather than the other.
