ENFORCER against its type

Built in 2003, it is 5 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 7,642 gross tonnage it is smaller than 97% of the other 3,000 container ships with a recorded tonnage. It is one of 21 container ships here under the Netherlands flag, 0.6% of the 3,495 on the register. The same builder is recorded for 52 other vessels here, 7 of them container ships. The returns for 2018–2025 all give Harlingen as port of registry.

Its 13,641 t of CO₂ for 2025 is 17% 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 237.8 kg CO₂, 56% below the type median of 545.6 kg. It logged 4,703 hours at sea against a median of 3,155 hours for its type that year. 2.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (20,905 t) and the lowest 2024 (12,599 t). Its efficiency percentile within the type went from 94 in 2018 to 99 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025

Position 1,816 of 1,838 qualifying container ships by EEOI, at the 99th percentile. The dashed line is the type median, 14.2; this vessel reported 62.4.

Reported CO₂ in 2025 was 34.7% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 8.3% while distance sailed rose 11.6%and CO₂ per nautical mile fell 2.9%.That points mainly to how much the vessel sailed, rather than the other.
