JAOHAR ADAM against its type

Built in 1997, it is 11 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 5,941 gross tonnage it is smaller than 100% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 30 other vessels here, 6 of them container ships. Its MRV returns name it ROMY TRADER for 2018–2019, JAOHAR ADAM for 2020–2021 and WEC BOUMEESTER for 2023–2025. The reported port of registry changed: Gibraltar (2018–2019), then Madeira (2023–2025).

Its 8,163 t of CO₂ for 2025 is 50% 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 222.0 kg CO₂, 59% below the type median of 545.6 kg. It logged 4,272 hours at sea against a median of 3,155 hours for its type that year. 3.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2018 (11,758 t) and the lowest 2020 (4,792 t). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 30.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions fell 11.5% and CO₂ per nautical mile rose 15.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 7 MRV reporting years, 5 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
