APIASTOS against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,990 gross tonnage it is larger than 88% 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 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it DL ROSE for 2019–2020, NEUTRON SOUND for 2022 and APIASTOS for 2024–2025. The reported port of registry changed: JEJU (2019–2020), then Majuro (2022), then Monrovia (2024–2025).
Its 2,181 t of CO₂ for 2024 is 63% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 359.6 kg CO₂, 42% above the type median of 253.5 kg. It logged 598 hours at sea against a median of 2,177 hours for its type that year. 3.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2019 (9,319 t) and the lowest 2024 (2,181 t). Its efficiency percentile within the type went from 86 in 2019 to 11 in 2022 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Reported CO₂ by year
Reported CO₂ in 2024 was 76.6% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.
From 2022 to 2024, emissions fell 61.7% and CO₂ per nautical mile rose 19.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

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