CHEM SAIPH against its type
It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. Its MRV returns name it NAVIG8 SAIPH for 2018 and CHEM SAIPH for 2023–2025. The reported port of registry changed: Majuro (2018), then Madeira (2023–2025).
Its 6,907 t of CO₂ for 2025 is 25% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 252.7 kg CO₂, close to the type median of 250.2 kg. It logged 2,459 hours at sea against a median of 2,106 hours for its type that year. 7.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (9,827 t) and the lowest 2018 (5,394 t). Its efficiency percentile within the type went from 64 in 2018 to 75 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,013 of 1,348 qualifying chemical tankers by EEOI, at the 75th percentile. The dashed line is the type median, 14.4; this vessel reported 23.1.
EEOI divides emissions by transport work, which for this vessel and year was 299,154,179 tonne-miles over 27,332 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 29.1% while distance sailed fell 25.0%and CO₂ per nautical mile fell 5.6%.That points mainly to how much the vessel sailed, rather than the other.
