STI ALEXIS 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 62,684 gross tonnage it is larger than 60% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 660 other vessels here, 159 of them oil tankers. The returns for 2018–2025 all give Majuro as port of registry.

Its 20,590 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 482.6 kg CO₂, 20% above the type median of 403.2 kg. It logged 3,616 hours at sea against a median of 2,030 hours for its type that year. 8.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2025 (20,590 t) and the lowest 2018 (3,630 t). Its efficiency percentile within the type went from 16 in 2018 to 60 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
