SEA GARNET against its type

At 81,364 gross tonnage it is larger 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 761 other vessels here, 193 of them oil tankers. The returns for 2019–2025 all give Majuro as port of registry.

Its 1,574 t of CO₂ for 2025 is 80% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 527.0 kg CO₂, 31% above the type median of 403.2 kg. It logged 386 hours at sea against a median of 2,030 hours for its type that year. 4.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2024 (24,700 t) and the lowest 2025 (1,574 t). Its efficiency percentile within the type went from 19 in 2018 to 35 in 2024 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 64.7% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 93.6% and CO₂ per nautical mile rose 20.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 8 MRV reporting years and 4 of 5 vessel particulars. Not found in the sources for this vessel: an efficiency ranking, 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.
