PATANI against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,935 gross tonnage it is smaller than 71% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The same builder is recorded for 98 other vessels here, 3 of them chemical tankers. Its MRV returns name it PATANI for 2018–2022 and SONGA TAURUS for 2023–2025. The reported port of registry changed: Valletta (2018–2019), then Madeira (2020–2025).
Its 8,272 t of CO₂ for 2025 is 50% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 274.2 kg CO₂, close to the type median of 250.2 kg. It logged 2,966 hours at sea against a median of 2,109 hours for its type that year. 11.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2021 (11,242 t) and the lowest 2023 (2,306 t). Its efficiency percentile within the type went from 87 in 2018 to 91 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.
