FWN SEA against its type
Built in 2016, it is 9 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,749 gross tonnage it is larger than 54% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 306 general cargo ships here under the Netherlands flag, 9.9% of the 3,081 on the register. The same builder is recorded for 98 other vessels here, all of them general cargo ships. Its MRV returns name it SYMPHONY SEA for 2018–2022 and FWN SEA for 2023–2025. The returns for 2018–2025 all give Rotterdam as port of registry.
Its 3,524 t of CO₂ for 2025 is 25% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 138.4 kg CO₂, 13% above the type median of 122.2 kg. It logged 2,790 hours at sea against a median of 3,044 hours for its type that year. 3.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2019 (6,901 t) and the lowest 2023 (1,454 t). Its efficiency percentile within the type went from 71 in 2018 to 36 in 2022 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 38.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 141.9% and CO₂ per nautical mile fell 10.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
