SEAMARLIN against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 26,548 gross tonnage it is smaller than 86% of the other 2,841 oil tankers with a recorded tonnage. It is one of 11 oil tankers here under the Germany flag, 0.3% of the 3,548 on the register. The same builder is recorded for 25 other vessels here, 14 of them oil tankers. The returns for 2018–2025 all give Bremen as port of registry.
Its 11,251 t of CO₂ for 2025 is 42% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 383.1 kg CO₂, close to the type median of 403.2 kg. It logged 2,742 hours at sea against a median of 2,030 hours for its type that year. 13.3% 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 (19,664 t) and the lowest 2025 (11,251 t). Its efficiency percentile within the type went from 90 in 2018 to 95 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,381 of 1,448 qualifying oil tankers by EEOI, at the 95th percentile. The dashed line is the type median, 7.5; this vessel reported 24.5.
EEOI divides emissions by transport work, which for this vessel and year was 459,409,963 tonne-miles over 29,372 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 40.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 19.5% while distance sailed fell 6.9%and CO₂ per nautical mile fell 13.6%.That points mainly to how efficiently it sailed, rather than the other.
