GENER8 STRENGTH 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 161,319 gross tonnage it is larger than 95% 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 194 other vessels here, 56 of them oil tankers. Its MRV returns name it GENER8 STRENGTH for 2018–2019 and SEAWAYS TYBEE for 2021–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 24,045 t of CO₂ for 2025 is 3.0 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 738.0 kg CO₂, 1.8 times the type median of 403.2 kg. It logged 2,863 hours at sea against a median of 2,030 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2025 (24,045 t) and the lowest 2022 (2,307 t). Its efficiency percentile within the type went from 2 in 2019 to 1 in 2022 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 20 of 1,771 qualifying oil tankers by EEOI, at the 1st percentile. The dashed line is the type median, 8.0; this vessel reported 2.7.
EEOI divides emissions by transport work, which for this vessel and year was 860,750,000 tonne-miles over 3,166 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 82.0% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 701.4% and CO₂ per nautical mile rose 29.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
