UNAYZAH against its type

Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 141,077 gross tonnage it is larger than 86% of the other 3,000 container ships with a recorded tonnage. It is one of 336 container ships here under the Malta flag, 9.6% of the 3,495 on the register. Its MRV returns name it UNAYZAH for 2020–2021 and UNAYZAH EXPRESS for 2022–2023. The reported port of registry changed: Valletta (2020–2021), then Monrovia (2022–2023).

Its 6,082 t of CO₂ for 2023 is 58% below the median of 14,627 t among the 1,920 container ships on this register that reported for 2023. Per nautical mile it emitted 906.0 kg CO₂, 1.8 times the type median of 509.2 kg. It logged 559 hours at sea against a median of 2,716 hours for its type that year. 6.3% of its 2023 emissions were at berth; the median for container ships was 4.0%. Across 4 years with reported emissions, the highest was 2021 (15,371 t) and the lowest 2020 (4,063 t). Its efficiency percentile within the type went from 25 in 2020 to 31 in 2023 (lower is more efficient).

Efficiency against its own type2023

Position 523 of 1,664 qualifying container ships by EEOI, at the 31st percentile. The dashed line is the type median, 17.4; this vessel reported 11.8.

EEOI divides emissions by transport work, which for this vessel and year was 514,105,664 tonne-miles over 6,713 nautical miles.

Reported CO₂ in 2023 was 49.7% higher than in 2020, for EU/EEA voyages only.

From 2022 to 2023, emissions fell 42.2% while distance sailed fell 47.8%and CO₂ per nautical mile rose 10.7%.That points mainly to how much the vessel sailed, rather than the other.
