JENNINGS BAY 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 29,735 gross tonnage it is smaller than 75% 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 180 other vessels here, 51 of them oil tankers. Its MRV returns name it JENNINGS BAY for 2018–2023 and SEAWAYS LOMA for 2025. The returns for 2018–2025 all give Majuro as port of registry.

Its 7,906 t of CO₂ for 2023 is close to the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 303.0 kg CO₂, 26% below the type median of 408.5 kg. It logged 2,535 hours at sea against a median of 1,807 hours for its type that year. 11.6% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 3 years with reported emissions, the highest was 2023 (7,906 t) and the lowest 2021 (1,429 t). Its efficiency percentile within the type went from 52 in 2018 to 73 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a lower 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 type2023

Position 1,184 of 1,615 qualifying oil tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 8.0; this vessel reported 10.9.

EEOI divides emissions by transport work, which for this vessel and year was 725,983,471 tonne-miles over 26,092 nautical miles.

Reported CO₂ by year

2018: 5,401 t20185,4012021: 1,429 t20212023: 7,906 t20237,906

Reported CO₂ in 2023 was 46.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2022, 2024, so the series has gaps.

From 2021 to 2023, emissions rose 453.2% and CO₂ per nautical mile rose 35.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
