DUGI OTOK against its type

Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 59,315 gross tonnage it is larger than 50% of the other 2,841 oil tankers with a recorded tonnage. It is one of 6 oil tankers here under the Croatia flag, 0.2% of the 3,548 on the register. The same builder is recorded for 56 other vessels here, 24 of them oil tankers. The returns for 2018–2025 all give Zadar as port of registry.

Its 20,525 t of CO₂ for 2025 is 2.6 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 487.8 kg CO₂, 21% above the type median of 403.2 kg. It logged 6,034 hours at sea against a median of 2,030 hours for its type that year. 14.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2020 (21,495 t) and the lowest 2023 (10,031 t). Its efficiency percentile within the type went from 47 in 2018 to 79 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.
