OM SINGAPORE 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 19,758 gross tonnage it is smaller than 92% 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 192 other vessels here, 71 of them oil tankers. Its MRV returns name it BRITTA MAERSK for 2018–2022 and OM SINGAPORE for 2023–2025. The reported port of registry changed: Dragoer (2018–2022), then Monrovia (2023–2025).

Its 3,730 t of CO₂ for 2025 is 53% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 203.4 kg CO₂, 50% below the type median of 403.2 kg. It logged 1,557 hours at sea against a median of 2,030 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2022 (8,929 t) and the lowest 2021 (3,244 t). Its efficiency percentile within the type went from 89 in 2018 to 80 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
