SILVER HEBA against its type
Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,375 gross tonnage it is smaller than 79% 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 983 other vessels here, 270 of them oil tankers. The returns for 2018–2025 all give Hong Kong as port of registry.
Its 6,539 t of CO₂ for 2025 is 17% 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 291.4 kg CO₂, 28% below the type median of 403.2 kg. It logged 2,316 hours at sea against a median of 2,030 hours for its type that year. 9.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2022 (8,063 t) and the lowest 2024 (733 t). Its efficiency percentile within the type went from 34 in 2018 to 64 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 935 of 1,448 qualifying oil tankers by EEOI, at the 64th percentile. The dashed line is the type median, 7.5; this vessel reported 8.8.
EEOI divides emissions by transport work, which for this vessel and year was 745,622,577 tonne-miles over 22,440 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 791.9% and CO₂ per nautical mile fell 30.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
