ASTRAL against its type

Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 7,636 gross tonnage it is smaller than 97% of the other 2,841 oil tankers with a recorded tonnage. It is one of 17 oil tankers here under the Sweden flag, 0.5% of the 3,548 on the register. The reported port of registry changed: Donso (2018–2022), then Donsö (2023–2025).

Its 8,436 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 186.8 kg CO₂, 54% below the type median of 403.2 kg. It logged 4,298 hours at sea against a median of 2,030 hours for its type that year. 11.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2020 (9,106 t) and the lowest 2019 (8,180 t). Its efficiency percentile within the type went from 98 in 2018 to 99 in 2025 (lower is more efficient). Of the 7 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 1,432 of 1,448 qualifying oil tankers by EEOI, at the 99th percentile. The dashed line is the type median, 7.5; this vessel reported 36.6.

Reported CO₂ in 2025 was 6.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 2.4% while distance sailed rose 0.7%and CO₂ per nautical mile rose 1.7%.That points mainly to how efficiently it sailed, rather than the other.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars, AIS movements in Norwegian waters and a licensed photograph. Not found in the sources for this vessel: 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.
