BOW HECTOR against its type

Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 20,145 gross tonnage it is smaller than 92% of the other 2,841 oil tankers with a recorded tonnage. It is one of 58 oil tankers here under the Norway flag, 1.6% of the 3,548 on the register. The same builder is recorded for 307 other vessels here, 48 of them oil tankers. The reported port of registry changed: Manila (2018–2019), then Bergen (2020–2025).

Its 4,527 t of CO₂ for 2025 is 43% 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 234.7 kg CO₂, 42% below the type median of 403.2 kg. It logged 1,507 hours at sea against a median of 2,030 hours for its type that year. 3.3% 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 (8,717 t) and the lowest 2023 (664 t). Its efficiency percentile within the type went from 41 in 2018 to 66 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 952 of 1,448 qualifying oil tankers by EEOI, at the 66th percentile. The dashed line is the type median, 7.5; this vessel reported 9.0.

EEOI divides emissions by transport work, which for this vessel and year was 504,703,456 tonne-miles over 19,292 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 47.6% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 48.1% while distance sailed fell 41.0%and CO₂ per nautical mile fell 12.0%.That points mainly to how much the vessel sailed, rather than the other.
