TAMARA against its type

Built in 2015, it is 5 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 82,043 gross tonnage it is larger than 78% 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 34 other vessels here, 20 of them oil tankers. The reported port of registry changed: Valletta (2018–2021), then Monrovia (2022–2025).

Its 19,353 t of CO₂ for 2025 is 2.4 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 444.4 kg CO₂, 10% above the type median of 403.2 kg. It logged 3,885 hours at sea against a median of 2,030 hours for its type that year. 7.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2019 (28,595 t) and the lowest 2021 (5,373 t). Its efficiency percentile within the type went from 30 in 2018 to 55 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025

Position 801 of 1,448 qualifying oil tankers by EEOI, at the 55th percentile. The dashed line is the type median, 7.5; this vessel reported 7.9.

Reported CO₂ in 2025 was 7.7% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 27.8% while distance sailed fell 28.8%and CO₂ per nautical mile rose 1.3%.That points mainly to how much the vessel sailed, rather than the other.
