HELENE JULIE against its type
Built in 2004, it is 3 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 8,938 gross tonnage it is larger than 62% 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. Its MRV returns name it LONGWAVE for 2018–2020, MANISA VERA for 2021–2022 and HELENE JULIE for 2023–2025. The returns for 2018–2025 all give Schoonhoven as port of registry.
Its 4,184 t of CO₂ for 2025 is 48% 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 146.5 kg CO₂, 20% above the type median of 122.2 kg. It logged 2,943 hours at sea against a median of 3,044 hours for its type that year. 3.8% 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 2020 (7,038 t) and the lowest 2025 (4,184 t). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018
Position 115 of 380 qualifying general cargo ships by EEOI, at the 30th percentile. The dashed line is the type median, 26.8; this vessel reported 20.2.
EEOI divides emissions by transport work, which for this vessel and year was 322,434,503 tonne-miles over 39,318 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 6.4% and CO₂ per nautical mile fell 0.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
