TANNHAUSER against its type

Built in 2020, it is 12 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 73,358 gross tonnage it is larger than 94% of the other 571 vehicle carriers with a recorded tonnage. It is one of 14 vehicle carriers here under the Sweden flag, 2.0% of the 713 on the register. The returns for 2023–2025 all give Stockholm as port of registry.

Its 16,970 t of CO₂ for 2025 is 2.4 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 331.9 kg CO₂, close to the type median of 309.1 kg. It logged 3,225 hours at sea against a median of 1,639 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2024 (19,676 t) and the lowest 2020 (5,088 t). Its efficiency percentile within the type went from 6 in 2020 to 7 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 31 of 423 qualifying vehicle carriers by EEOI, at the 7th percentile. The dashed line is the type median, 51.7; this vessel reported 32.1.

Reported CO₂ in 2025 was 233.6% higher than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 13.8% while distance sailed fell 19.2%and CO₂ per nautical mile rose 6.7%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
