CHALLENGE PASSAGE: CO₂ emissions 2018–2022

CHALLENGE PASSAGE 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 28,823 gross tonnage it is smaller than 80% of the other 2,841 oil tankers with a recorded tonnage. It is one of 244 oil tankers here under the Panama flag, 6.9% of the 3,548 on the register. The same builder is recorded for 114 other vessels here, 20 of them oil tankers. The returns for 2018–2021 all give Panama as port of registry.

Its 2,642 t of CO₂ for 2022 is 63% below the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 262.3 kg CO₂, 37% below the type median of 415.9 kg. It logged 865 hours at sea against a median of 1,731 hours for its type that year. 7.6% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 4 years with reported emissions, the highest was 2020 (10,090 t) and the lowest 2018 (1,730 t). Its efficiency percentile within the type went from 86 in 2020 to 48 in 2022 (lower is more efficient). Of the 4 sister ships listed below with a 2022 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022

Position 847 of 1,771 qualifying oil tankers by EEOI, at the 48th percentile. The dashed line is the type median, 8.0; this vessel reported 7.8.

EEOI divides emissions by transport work, which for this vessel and year was 337,822,251 tonne-miles over 10,073 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 52.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.

From 2021 to 2022, emissions fell 46.6% while distance sailed fell 34.7%and CO₂ per nautical mile fell 18.2%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

• Emissions: EU MRV publication (THETIS-MRV), reporting years 2018–2022, published by the European Commission.
• Vessel particulars: Wikidata (CC0).

This page draws on 4 MRV reporting years, an efficiency ranking and 5 of 5 vessel particulars. Not found in the sources for this vessel: AIS movements in Norwegian waters, a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
