BUNGA ALLIUM against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 25,709 gross tonnage it is smaller than 87% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. Its MRV returns name it BUNGA ALLIUM for 2018 and HELENE MAERSK for 2019–2025. The reported port of registry changed: Port Klang (2018), then Sinapore (2019), then Singapore (2020–2025).
Its 5,796 t of CO₂ for 2025 is 27% 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 243.3 kg CO₂, 40% below the type median of 403.2 kg. It logged 2,038 hours at sea against a median of 2,030 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2023 (13,537 t) and the lowest 2019 (2,130 t). Its efficiency percentile within the type went from 50 in 2018 to 65 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
