HAFNIA EXCEL against its type
Built in 2015, it is 5 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,750 gross tonnage it is smaller than 60% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. Its MRV returns name it STI EXCEL for 2018–2021 and HAFNIA EXCEL for 2022–2025. The reported port of registry changed: Majuro (2018–2021), then Singapore (2022–2025).
Its 5,222 t of CO₂ for 2025 is 34% 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 381.5 kg CO₂, close to the type median of 403.2 kg. It logged 1,284 hours at sea against a median of 2,030 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2018 (12,403 t) and the lowest 2022 (2,885 t). Its efficiency percentile within the type went from 50 in 2018 to 56 in 2025 (lower is more efficient).

Efficiency against its own type2025
Position 821 of 1,448 qualifying oil tankers by EEOI, at the 56th percentile. The dashed line is the type median, 7.5; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 656,874,214 tonne-miles over 13,689 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 37.4% while distance sailed fell 45.1%and CO₂ per nautical mile rose 14.0%.That points mainly to how much the vessel sailed, rather than the other.
