GULF LOYALTY against its type

Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 163,066 gross tonnage it is larger than 97% 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 761 other vessels here, 193 of them oil tankers. The returns for 2024–2025 all give Majuro as port of registry.

Its 16,145 t of CO₂ for 2025 is 2.0 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 665.8 kg CO₂, 1.7 times the type median of 403.2 kg. It logged 2,191 hours at sea against a median of 2,030 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Its efficiency percentile within the type went from 2 in 2024 to 23 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

EEOI divides emissions by transport work, which for this vessel and year was 2,973,209,945 tonne-miles over 24,249 nautical miles.

Reported CO₂ by year

2024: 4,058 t20244,0582025: 16,145 t202516,145

Reported CO₂ in 2025 was 297.8% higher than in 2024, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 297.8% while distance sailed rose 336.5%and CO₂ per nautical mile fell 8.9%.That points mainly to how much the vessel sailed, rather than the other.
