HIGH BEAM against its type
Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 28,231 gross tonnage it is smaller than 83% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 10 other vessels here, one of them an oil tanker. Its MRV returns name it HIGH BEAM for 2018 and IMPERIAL for 2020–2024. The reported port of registry changed: PANAMA (2018), then Monrovia (2020–2024).
Its 5,123 t of CO₂ for 2024 is 37% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 275.1 kg CO₂, 33% below the type median of 408.2 kg. It logged 1,506 hours at sea against a median of 2,020 hours for its type that year. 8.3% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 5 years with reported emissions, the highest was 2023 (5,528 t) and the lowest 2020 (1,475 t). Its efficiency percentile within the type went from 67 in 2018 to 62 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 976 of 1,566 qualifying oil tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 7.6; this vessel reported 8.6.
EEOI divides emissions by transport work, which for this vessel and year was 594,993,031 tonne-miles over 18,623 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 18.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, so the series has gaps.
From 2023 to 2024, emissions fell 7.3% while distance sailed fell 9.1%and CO₂ per nautical mile rose 2.0%.That points mainly to how much the vessel sailed, rather than the other.
