HELENE against its type
Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,996 gross tonnage it is smaller than 89% of the other 3,000 container ships with a recorded tonnage. It is one of 73 container ships here under the Antigua and Barbuda flag, 2.1% of the 3,495 on the register. The same builder is recorded for 19 other vessels here, 9 of them container ships. Its MRV returns name it HOHEWEG for 2018–2019 and HELENE for 2021–2025. The returns for 2018–2025 all give St.John’s as port of registry.
Its 7,714 t of CO₂ for 2025 is 53% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 312.2 kg CO₂, 43% below the type median of 545.6 kg. It logged 3,503 hours at sea against a median of 3,155 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2024 (9,282 t) and the lowest 2023 (3,732 t). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 16.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 16.9% and CO₂ per nautical mile fell 0.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
