CPO NORFOLK against its type

Built in 2009, it is 1 year newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 41,358 gross tonnage it is smaller than 53% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. CPO Containerschiffreederei is linked to 60 vessels on this register. Its MRV returns name it CPO NORFOLK for 2019–2020 and NORFOLK for 2023. The returns for 2019–2023 all give Monrovia as port of registry.

Its 2,963 t of CO₂ for 2023 is 80% 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 557.7 kg CO₂, close to the type median of 509.2 kg. It logged 348 hours at sea against a median of 2,716 hours for its type that year. 0.8% of its 2023 emissions were at berth; the median for container ships was 4.0%. Across 3 years with reported emissions, the highest was 2020 (3,457 t) and the lowest 2019 (2,906 t). The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2023

Position 661 of 1,664 qualifying container ships by EEOI, at the 40th percentile. The dashed line is the type median, 17.4; this vessel reported 13.9.

Across the 54 ranked vessels operated by CPO Containerschiffreederei, the median percentile is 48. This vessel is more efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 213,656,092 tonne-miles over 5,313 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 2.0% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.

From 2020 to 2023, emissions fell 14.3% and CO₂ per nautical mile rose 33.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
