WALLEYE against its type
Built in 2003, it is 7 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,771 gross tonnage it is smaller than 60% 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 660 other vessels here, 159 of them oil tankers. The reported port of registry changed: Majuro (2019), then Majuro, Marshall Islands (2020).
Its 2,733 t of CO₂ for 2020 is 69% below the median of 8,732 t among the 1,884 oil tankers on this register that reported for 2020. Per nautical mile it emitted 476.1 kg CO₂, 12% above the type median of 424.6 kg. It logged 491 hours at sea against a median of 1,939 hours for its type that year. 7.6% of its 2020 emissions were at berth; the median for oil tankers was 8.6%. Across 3 years with reported emissions, the highest was 2019 (5,560 t) and the lowest 2018 (2,547 t). Its efficiency percentile within the type went from 61 in 2019 to 67 in 2020 (lower is more efficient). The one sister ship listed below with a 2020 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2020
Position 1,138 of 1,708 qualifying oil tankers by EEOI, at the 67th percentile. The dashed line is the type median, 8.7; this vessel reported 11.1.
EEOI divides emissions by transport work, which for this vessel and year was 246,909,666 tonne-miles over 5,741 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2020 was 7.3% higher than in 2018, for EU/EEA voyages only.
From 2019 to 2020, emissions fell 50.8% while distance sailed fell 60.0%and CO₂ per nautical mile rose 23.0%.That points mainly to how much the vessel sailed, rather than the other.
