KIISLA against its type
Built in 2004, it is 6 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 9,910 gross tonnage it is smaller than 96% 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 22 other vessels here, one of them an oil tanker. Its MRV returns name it KIISLA for 2018–2024 and PRIME for 2025. The reported port of registry changed: Porvoo (2018–2022), then Arendal (2023–2025).
Its 9,227 t of CO₂ for 2025 is 16% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 246.1 kg CO₂, 39% below the type median of 403.2 kg. It logged 3,525 hours at sea against a median of 2,030 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (14,362 t) and the lowest 2025 (9,227 t). Its efficiency percentile within the type went from 99 in 2018 to 98 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 1,423 of 1,448 qualifying oil tankers by EEOI, at the 98th percentile. The dashed line is the type median, 7.5; this vessel reported 32.7.
EEOI divides emissions by transport work, which for this vessel and year was 281,926,978 tonne-miles over 37,495 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 10.7% and CO₂ per nautical mile fell 4.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
