ANCHOR 18 against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 12,862 gross tonnage it is smaller than 65% 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 95 other vessels here, 6 of them chemical tankers. Its MRV returns name it SUSANA S for 2018–2022 and ANCHOR 18 for 2023–2025. The reported port of registry changed: Bergen (2018–2022), then MONROVIA (2023–2025).
Its 7,888 t of CO₂ for 2025 is 43% 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 329.9 kg CO₂, 32% above the type median of 250.2 kg. It logged 2,175 hours at sea against a median of 2,109 hours for its type that year. 4.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2018 (22,208 t) and the lowest 2023 (5,129 t). Its efficiency percentile within the type went from 79 in 2018 to 84 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 1,132 of 1,348 qualifying chemical tankers by EEOI, at the 84th percentile. The dashed line is the type median, 14.4; this vessel reported 29.8.
EEOI divides emissions by transport work, which for this vessel and year was 264,522,804 tonne-miles over 23,910 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 64.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 53.8% while distance sailed rose 36.5%and CO₂ per nautical mile rose 12.7%.That points mainly to how much the vessel sailed, rather than the other.
