DELFT SEAWAYS against its type

Built in 2006, it is 6 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 35,293 gross tonnage it is larger than 80% of the other 470 ro-pax ships with a recorded tonnage. It is one of 19 ro-pax ships here under the United Kingdom flag, 3.9% of the 493 on the register. The same builder is recorded for 563 other vessels here, 7 of them ro-pax ships. DFDS is linked to 6 vessels on this register. The returns for 2018–2025 all give Dover as port of registry.

Its 42,747 t of CO₂ for 2025 is 42% above the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 567.8 kg CO₂, 21% above the type median of 467.6 kg. It logged 4,902 hours at sea against a median of 4,243 hours for its type that year. 8.1% 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 2019 (60,501 t) and the lowest 2025 (42,747 t). 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 type2018

Position 7 of 18 qualifying ro-pax ships by EEOI, at the 35th percentile. The dashed line is the type median, 335.9; this vessel reported 298.3.

0255075100more efficientless efficientThis vessel: 35th percentile, EEOI 298.3

Across the 5 ranked vessels operated by DFDS, the median percentile is 47. This vessel is more efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 30,942,095 passenger-miles over 93,880 nautical miles.

Reported CO₂ in 2025 was 21.6% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 1.4% and CO₂ per nautical mile rose 0.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
