DROTTEN against its type

Built in 2003, it is 3 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 29,746 gross tonnage it is larger than 66% of the other 470 ro-pax ships with a recorded tonnage. It is one of 20 ro-pax ships here under the Sweden flag, 4.1% of the 493 on the register. The same builder is recorded for 192 other vessels here, 7 of them ro-pax ships. Destination Gotland is linked to 3 vessels on this register. Its MRV returns name it GOTLAND for 2018–2019 and DROTTEN for 2020–2025. The returns for 2018–2025 all give Visby as port of registry.

Its 28,063 t of CO₂ for 2025 is close to the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 720.7 kg CO₂, 1.5 times the type median of 467.6 kg. It logged 1,816 hours at sea against a median of 4,243 hours for its type that year. 11.1% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 8 years with reported emissions, the highest was 2022 (71,818 t) and the lowest 2020 (13,757 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ in 2025 was 58.7% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 9.5% and CO₂ per nautical mile rose 2.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 8 MRV reporting years, 5 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, 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.
