MAISTROS against its type

Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,010 gross tonnage it is smaller than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2018–2025 all give Monrovia as port of registry.

Its 1,914 t of CO₂ for 2025 is 76% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 390.6 kg CO₂, close to the type median of 403.2 kg. It logged 886 hours at sea against a median of 2,030 hours for its type that year. 13.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2022 (3,456 t) and the lowest 2025 (1,914 t). Its efficiency percentile within the type went from 76 in 2022 to 40 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 585 of 1,448 qualifying oil tankers by EEOI, at the 40th percentile. The dashed line is the type median, 7.5; this vessel reported 6.8.

Reported CO₂ in 2025 was 14.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.

From 2023 to 2025, emissions fell 38.3% while distance sailed fell 34.7%and CO₂ per nautical mile fell 5.4%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

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