COSFLYING LAKE against its type

Built in 2015, it is 5 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 159,819 gross tonnage it is larger than 91% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The returns for 2019–2025 all give HONGKONG as port of registry.

Its 12,386 t of CO₂ for 2024 is 1.5 times the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 632.5 kg CO₂, 1.5 times the type median of 408.2 kg. It logged 1,632 hours at sea against a median of 2,020 hours for its type that year. 3.5% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Its efficiency percentile within the type went from 3 in 2019 to 5 in 2024 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024

Position 81 of 1,566 qualifying oil tankers by EEOI, at the 5th percentile. The dashed line is the type median, 7.6; this vessel reported 3.7.

EEOI divides emissions by transport work, which for this vessel and year was 3,356,737,127 tonne-miles over 19,584 nautical miles.

Reported CO₂ by year

2019: 12,436 t201912,4362024: 12,386 t202412,386

Reported CO₂ in 2024 was 0.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.

From 2019 to 2024, emissions fell 0.4% while distance sailed fell 0.9%and CO₂ per nautical mile rose 0.5%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 3 MRV reporting years, an efficiency ranking and 4 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.
