A digital twin for one of Europe’s busiest container ports

NorthSea Container Terminal handles 14,000 vessel calls per year at the mouth of Europe’s busiest shipping lane. Berth planning, crane allocation, and truck gate scheduling lived in separate systems — each optimized locally, none optimized for the whole port.

Ships waiting, cranes waiting, trucks waiting

Sofia Lindström’s operations team managed a daily puzzle: which vessel gets which berth, which cranes serve which bay, and how many trucks the gate can absorb when containers unload. A delay at berth 7 rippled into crane reassignment, missed rail connections, and trucks queued at the gate with engines running.

We were world-class at moving containers and amateur at connecting the dots between arrival, berth, and departure.

A twin that sees the whole terminal

Netisen built a digital twin that models the terminal in fifteen-minute increments — vessel ETAs, crane availability, yard capacity, and gate throughput. Planners run scenarios before committing berths. When a vessel reports a delayed arrival, the twin recalculates downstream impact and suggests reassignments before manual replanning begins.

• Live berth schedule with what-if simulation for weather and equipment outages
• Crane utilization heatmaps tied to actual hoist cycle telemetry
• Gate appointment system synced to yard container availability
• Emissions dashboard for berthed vessels and truck queue times

Results the shipping lines noticed

Within two quarters, average vessel wait time dropped from 4.2 hours to 3.3 hours. Two major shipping alliances cited improved turnaround in contract renewal discussions. Lindström’s team tracks crane idle hours as closely as revenue — both improved in the same period.

The emissions reduction was a secondary goal that became a primary talking point. Port authorities across the North Sea now visit to study the twin’s truck-queue model.
