SILVERWAY against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,545 gross tonnage it is larger than 77% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 196 other vessels here, 75 of them oil tankers. The returns for 2018–2025 all give Monrovia as port of registry.
Its 27,124 t of CO₂ for 2025 is 3.4 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 454.2 kg CO₂, 13% above the type median of 403.2 kg. It logged 5,533 hours at sea against a median of 2,030 hours for its type that year. 4.8% 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 (28,275 t) and the lowest 2022 (3,235 t). Its efficiency percentile within the type went from 12 in 2018 to 43 in 2025 (lower is more efficient). Of the 4 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 629 of 1,448 qualifying oil tankers by EEOI, at the 43rd percentile. The dashed line is the type median, 7.5; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 3,897,054,598 tonne-miles over 59,718 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 232.0% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.1% while distance sailed fell 8.5%and CO₂ per nautical mile rose 4.8%.That points mainly to how much the vessel sailed, rather than the other.
