JOLLY COBALTO against its type
Built in 2015, it is 5 years newer than the median container/ro-ro cargo ship on this register, which was built in 2010 (72 vessels with a known build year). At 51,055 gross tonnage it is larger than 52% of the other 71 container/ro-ro cargo ships with a recorded tonnage. It is one of 4 container/ro-ro cargo ships here under the Marshall Islands flag, 5.3% of the 75 on the register. Its MRV returns name it JOLLY COBALTO for 2018–2022 and RAMHAN for 2024–2025. The reported port of registry changed: Genoa (2018–2022), then Majuro (2024–2025).
Its 1,797 t of CO₂ for 2025 is 90% below the median of 18,174 t among the 60 container/ro-ro cargo ships on this register that reported for 2025. Per nautical mile it emitted 417.3 kg CO₂, close to the type median of 419.6 kg. It logged 339 hours at sea against a median of 3,323 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for container/ro-ro cargo ships was 4.5%. Across 7 years with reported emissions, the highest was 2018 (41,801 t) and the lowest 2025 (1,797 t). Of the 3 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 95.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 82.5% and CO₂ per nautical mile fell 30.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

This page draws on 7 MRV reporting years, 4 of 5 vessel particulars and a name history. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a licensed photograph, 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.
