OTTOMAN INTEGRITY against its type

Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 80,112 gross tonnage it is larger than 70% of the other 2,841 oil tankers with a recorded tonnage. It is one of 27 oil tankers here under the Türkiye flag, 0.8% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The returns for 2018–2025 all give Istanbul as port of registry.

Its 30,490 t of CO₂ for 2025 is 3.8 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 525.6 kg CO₂, 30% above the type median of 403.2 kg. It logged 5,226 hours at sea against a median of 2,030 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2025 (30,490 t) and the lowest 2020 (5,127 t). Its efficiency percentile within the type went from 29 in 2018 to 73 in 2025 (lower is more efficient). Of the 3 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 1,060 of 1,448 qualifying oil tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 7.5; this vessel reported 10.2.

EEOI divides emissions by transport work, which for this vessel and year was 2,977,548,828 tonne-miles over 58,014 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 58.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions rose 115.7% while distance sailed rose 99.3%and CO₂ per nautical mile rose 8.2%.That points mainly to how much the vessel sailed, rather than the other.
