TIRRANNA against its type

Built in 2009, it is 1 year newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 71,673 gross tonnage it is larger than 90% of the other 571 vehicle carriers with a recorded tonnage. It is one of 54 vehicle carriers here under the Norway flag, 7.6% of the 713 on the register. The same builder is recorded for 660 other vessels here, 45 of them vehicle carriers. The reported port of registry changed: Tonsberg (2018–2022), then Tønsberg (2023–2025).

Its 6,165 t of CO₂ for 2025 is 13% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 334.7 kg CO₂, close to the type median of 309.1 kg. It logged 1,370 hours at sea against a median of 1,639 hours for its type that year. 7.2% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2018 (13,673 t) and the lowest 2022 (2,819 t). Its efficiency percentile within the type went from 48 in 2018 to 23 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 98 of 423 qualifying vehicle carriers by EEOI, at the 23rd percentile. The dashed line is the type median, 51.7; this vessel reported 40.4.

EEOI divides emissions by transport work, which for this vessel and year was 152,704,731 tonne-miles over 18,419 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 54.9% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 28.3% while distance sailed fell 21.9%and CO₂ per nautical mile fell 8.2%.That points mainly to how much the vessel sailed, rather than the other.
