BRYANSTON against its type
Built in 2005, it is 5 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 58,722 gross tonnage it is smaller than 50% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. Its MRV returns name it PHOENIX DREAM for 2018 and BRYANSTON for 2019–2021. The reported port of registry changed: PANAMA (2018), then Majuro (2019–2021).
Its 7,858 t of CO₂ for 2021 is close to the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 492.7 kg CO₂, 20% above the type median of 409.1 kg. It logged 1,295 hours at sea against a median of 1,921 hours for its type that year. 21.1% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 3 years with reported emissions, the highest was 2018 (19,653 t) and the lowest 2019 (6,937 t). Its efficiency percentile within the type went from 55 in 2018 to 86 in 2021 (lower is more efficient).

Efficiency against its own type2021
Position 1,405 of 1,636 qualifying oil tankers by EEOI, at the 86th percentile. The dashed line is the type median, 8.4; this vessel reported 16.7.
EEOI divides emissions by transport work, which for this vessel and year was 469,980,263 tonne-miles over 15,948 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 60.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2019 to 2021, emissions rose 13.3% while distance sailed rose 4.4%and CO₂ per nautical mile rose 8.5%.That points mainly to how efficiently it sailed, rather than the other.
Where the 2021 emissions occurred
Laden voyages2021
- CO₂ on laden voyages
