RT STAR against its type

Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 16,363 gross tonnage it is smaller than 60% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 307 other vessels here, 98 of them chemical tankers. Its MRV returns name it RT STAR for 2018–2022 and TG TAURUS for 2023–2024. The reported port of registry changed: Manila (2018–2022), then MONROVIA (2023–2024).

Its 6,186 t of CO₂ for 2024 is close to the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 299.2 kg CO₂, 18% above the type median of 253.5 kg. It logged 1,798 hours at sea against a median of 2,177 hours for its type that year. 2.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2018 (10,515 t) and the lowest 2021 (1,626 t). Its efficiency percentile within the type went from 69 in 2018 to 60 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.
