GARDENIA SEAWAYS 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 32,336 gross tonnage it is larger than 77% of the other 269 ro-ro ships with a recorded tonnage. It is one of 18 ro-ro ships here under the Türkiye flag, 5.8% of the 311 on the register. The same builder is recorded for 59 other vessels here, 45 of them ro-ro ships. DFDS Seaways is linked to 5 vessels on this register. Its MRV returns name it GARDENIA SEAWAYS for 2018–2021 and ULUSOY-16 for 2022–2025. The reported port of registry changed: Klaipeda (2018–2021), then ISTANBUL (2022–2025).

Its 29,376 t of CO₂ for 2025 is 38% 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 296.0 kg CO₂, close to the type median of 327.0 kg. It logged 6,288 hours at sea against a median of 4,872 hours for its type that year. 1.0% 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 2023 (31,917 t) and the lowest 2022 (24,415 t). Its efficiency percentile within the type went from 46 in 2018 to 19 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 38 of 192 qualifying ro-ro ships by EEOI, at the 19th percentile. The dashed line is the type median, 85.3; this vessel reported 54.1.

Across the 3 ranked vessels operated by DFDS Seaways, the median percentile is 65. This vessel is more efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 543,292,399 tonne-miles over 99,249 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 9.2% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 0.5% while distance sailed fell 0.1%and CO₂ per nautical mile fell 0.4%.That points mainly to how efficiently it sailed, rather than the other.
