GRENDI STAR against its type

Built in 2017, it is 15 years newer than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 24,133 gross tonnage it is larger than 61% of the other 269 ro-ro ships with a recorded tonnage. It is one of 25 ro-ro ships here under the Italy flag, 8.0% of the 311 on the register. Its MRV returns name it ML FREYJA for 2018–2024 and GRENDI STAR for 2025. The reported port of registry changed: Venezia - RI 045 (2018–2020), then Venice (2021–2025).

Its 24,165 t of CO₂ for 2025 is 13% above the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 302.1 kg CO₂, close to the type median of 327.0 kg. It logged 5,690 hours at sea against a median of 4,872 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2018 (56,124 t) and the lowest 2025 (24,165 t). Its efficiency percentile within the type went from 30 in 2019 to 31 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 60 of 192 qualifying ro-ro ships by EEOI, at the 31st percentile. The dashed line is the type median, 85.3; this vessel reported 69.4.

0255075100more efficientless efficientThis vessel: 31st percentile, EEOI 69.4

EEOI divides emissions by transport work, which for this vessel and year was 348,198,559 tonne-miles over 79,995 nautical miles.

Reported CO₂ in 2025 was 56.9% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 20.2% while distance sailed fell 18.2%and CO₂ per nautical mile fell 2.4%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 8 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: AIS movements in Norwegian waters, 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.
