SEAFRONTIER 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 30,241 gross tonnage it is smaller than 70% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The same builder is recorded for 192 other vessels here, 71 of them oil tankers. The returns for 2019–2025 all give Hong Kong as port of registry.

Its 5,059 t of CO₂ for 2025 is 36% 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 344.7 kg CO₂, 14% below the type median of 403.2 kg. It logged 1,411 hours at sea against a median of 2,030 hours for its type that year. 9.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2019 (12,932 t) and the lowest 2022 (2,577 t). Its efficiency percentile within the type went from 87 in 2019 to 84 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,218 of 1,448 qualifying oil tankers by EEOI, at the 84th percentile. The dashed line is the type median, 7.5; this vessel reported 13.7.

EEOI divides emissions by transport work, which for this vessel and year was 370,617,582 tonne-miles over 14,675 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 60.9% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions rose 96.3% while distance sailed rose 93.6%and CO₂ per nautical mile rose 1.4%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 5,138 t
Methane (CH₄): 0.08 t
Nitrous oxide (N₂O): 0.29 t
