CATALAN SEA against its type

Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 64,089 gross tonnage it is larger than 66% 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 same builder is recorded for 196 other vessels here, 75 of them oil tankers. The returns for 2018–2025 all give Monrovia as port of registry.

Its 25,850 t of CO₂ for 2025 is 3.3 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 462.0 kg CO₂, 15% above the type median of 403.2 kg. It logged 5,388 hours at sea against a median of 2,030 hours for its type that year. 7.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2024 (26,369 t) and the lowest 2019 (3,402 t). Its efficiency percentile within the type went from 46 in 2018 to 66 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 962 of 1,448 qualifying oil tankers by EEOI, at the 66th percentile. The dashed line is the type median, 7.5; this vessel reported 9.1.

0255075100more efficientless efficientThis vessel: 66th percentile, EEOI 9.1

EEOI divides emissions by transport work, which for this vessel and year was 2,853,248,344 tonne-miles over 55,950 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 394.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 2.0% while distance sailed rose 1.5%and CO₂ per nautical mile fell 3.4%.That points mainly to how efficiently it sailed, rather than the other.

Sources and how to read this

This page draws on 7 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: 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.
