GENER8 CHIOTIS against its type

It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. Its MRV returns name it GENER8 CHIOTIS for 2018 and SEAWAYS LIBERTY for 2021–2025. The returns for 2018–2025 all give MAJURO as port of registry.

Its 6,148 t of CO₂ for 2024 is 25% 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 586.5 kg CO₂, 44% above the type median of 408.2 kg. It logged 1,055 hours at sea against a median of 2,020 hours for its type that year. 5.7% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 3 years with reported emissions, the highest was 2021 (13,129 t) and the lowest 2022 (5,278 t). Its efficiency percentile within the type went from 2 in 2021 to 10 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.

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 157 of 1,566 qualifying oil tankers by EEOI, at the 10th percentile. The dashed line is the type median, 7.6; this vessel reported 4.3.

2021: 13,129 t202113,1292022: 5,278 t20222024: 6,148 t20246,148

Reported CO₂ in 2024 was 53.2% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2023, so the series has gaps.

From 2022 to 2024, emissions rose 16.5% while distance sailed rose 12.1%and CO₂ per nautical mile rose 3.9%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 5 MRV reporting years, an efficiency ranking, 1 of 5 vessel particulars and a name history. Not found in the sources for this vessel: AIS movements in Norwegian waters, 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.
