ONYX against its type
Built in 1999, it is 11 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 10,321 gross tonnage it is smaller than 96% of the other 2,841 oil tankers with a recorded tonnage. It is the only oil tanker on this register under the Latvia flag. The same builder is recorded for 61 other vessels here. Its MRV returns name it ONYX for 2018–2022 and ONYX 1 for 2023. The reported port of registry changed: Riga (2018–2022), then Freetown (2023).
Its 8,329 t of CO₂ for 2023 is 11% above the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 313.6 kg CO₂, 23% below the type median of 408.5 kg. It logged 2,085 hours at sea against a median of 1,807 hours for its type that year. 4.7% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 6 years with reported emissions, the highest was 2019 (11,892 t) and the lowest 2018 (6,100 t). Its efficiency percentile within the type went from 95 in 2018 to 99 in 2023 (lower is more efficient).
