NORFOLK EXPRESS against its type

Built in 2013, it is 5 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 148,667 gross tonnage it is larger than 90% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. Its MRV returns name it THALASSA HELLAS for 2018–2022 and NORFOLK EXPRESS for 2023–2025. The returns for 2018–2025 all give Singapore as port of registry.

Its 27,461 t of CO₂ for 2025 is 1.7 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 783.9 kg CO₂, 44% above the type median of 545.6 kg. It logged 2,426 hours at sea against a median of 3,155 hours for its type that year. 2.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2021 (59,092 t) and the lowest 2025 (27,461 t). Its efficiency percentile within the type went from 11 in 2018 to 8 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 140 of 1,838 qualifying container ships by EEOI, at the 8th percentile. The dashed line is the type median, 14.2; this vessel reported 6.6.

EEOI divides emissions by transport work, which for this vessel and year was 4,135,697,289 tonne-miles over 35,031 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 7.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2024, so the series has gaps.

From 2023 to 2025, emissions fell 18.4% while distance sailed fell 14.2%and CO₂ per nautical mile fell 5.0%.That points mainly to how much the vessel sailed, rather than the other.
