FWN SKY against its type

Built in 2015, it is 8 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 SKY for 2018–2022 and FWN SKY for 2023–2025. The returns for 2018–2025 all give Rotterdam as port of registry.

Its 4,489 t of CO₂ for 2025 is 1.6 times 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 136.2 kg CO₂, 11% above the type median of 122.2 kg. It logged 3,076 hours at sea against a median of 3,044 hours for its type that year. 5.1% 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 2018 (6,662 t) and the lowest 2022 (3,944 t). Its efficiency percentile within the type went from 41 in 2018 to 91 in 2023 (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.

Efficiency against its own type2023

Position 302 of 331 qualifying general cargo ships by EEOI, at the 91st percentile. The dashed line is the type median, 21.1; this vessel reported 45.9.

EEOI divides emissions by transport work, which for this vessel and year was 139,273,500 tonne-miles over 49,671 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 32.6% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 16.9% and CO₂ per nautical mile fell 3.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
