VIRENT against its type

Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,266 gross tonnage it is smaller than 79% of the other 2,841 oil tankers with a recorded tonnage. It is one of 58 oil tankers here under the Norway flag, 1.6% of the 3,548 on the register. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. Thome Ship Management is linked to 42 vessels on this register. Its MRV returns name it JO ASK for 2020–2021 and ELLORA for 2023. The reported port of registry changed: Bergen (2020–2021), then Panama (2023).

Its 2,631 t of CO₂ for 2023 is 65% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 352.4 kg CO₂, 14% below the type median of 408.5 kg. It logged 714 hours at sea against a median of 1,807 hours for its type that year. 10.1% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 3 years with reported emissions, the highest was 2021 (3,371 t) and the lowest 2020 (2,524 t). Its efficiency percentile within the type went from 19 in 2020 to 72 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023

Position 1,167 of 1,615 qualifying oil tankers by EEOI, at the 72nd percentile. The dashed line is the type median, 8.0; this vessel reported 10.7.

Across the 39 ranked vessels operated by Thome Ship Management, the median percentile is 54. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 245,157,502 tonne-miles over 7,464 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 4.2% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2021 to 2023, emissions fell 22.0% while distance sailed fell 46.0%and CO₂ per nautical mile rose 44.4%.
