SOMERSET against its type

Built in 1999, it is 3 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 21,005 gross tonnage it is smaller than 52% of the other 269 ro-ro ships with a recorded tonnage. It is one of 52 ro-ro ships here under the Malta flag, 16.7% of the 311 on the register. The same builder is recorded for 15 other vessels here, 3 of them ro-ro ships. The reported port of registry changed: Hoek van Holland (2018–2022), then Valletta (2023–2025).

Its 15,884 t of CO₂ for 2025 is 26% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 246.8 kg CO₂, 25% below the type median of 327.0 kg. It logged 4,712 hours at sea against a median of 4,872 hours for its type that year. 7.3% 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 2024 (22,585 t) and the lowest 2018 (14,338 t). Its efficiency percentile within the type went from 70 in 2019 to 42 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 82 of 192 qualifying ro-ro ships by EEOI, at the 42nd percentile. The dashed line is the type median, 85.3; this vessel reported 78.9.

Reported CO₂ in 2025 was 10.8% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 29.7% while distance sailed fell 21.3%and CO₂ per nautical mile fell 10.6%.That points mainly to how much the vessel sailed, rather than the other.
