Pilbara Ports iron ore record: capacity and scheduling takeaways for planners

30 Second Briefing
Pilbara Ports handled a record December throughput of 71.2Mt in 2025, driven primarily by iron ore exports through its major Pilbara hubs. The Port of Port Hedland and the Port of Dampier, which together service BHP, Rio Tinto and other iron ore producers, sustained high vessel movements and loading rates despite cyclone-season constraints. The figures signal continued pressure on channel dredging, berthing windows and stockyard management, with planners likely to reassess capacity envelopes and maintenance scheduling for 2026.
Technical Brief
- High shiploader utilisation at Port Hedland and Dampier implies minimal downtime windows for wharf maintenance.
- Cyclone-season operations required tighter metocean monitoring to maintain safe under-keel clearance in dredged channels.
- Stockyard reclaim and stacking rates had to match elevated vessel line-up to avoid berth demurrage.
- Channel congestion risk increases pressure on dynamic vessel scheduling and tidal window optimisation tools.
- Elevated iron ore export volumes will drive earlier review of dredging campaigns and sedimentation monitoring strategies.
Our Take
The 71.2 Mt December 2025 throughput at Pilbara Ports aligns with recent coverage of BHP–Rio Tinto plans for up to 200 Mt of joint Pilbara iron ore output, signalling that port capacity and scheduling at Dampier will be a critical constraint to coordinate if that mine-side collaboration advances.
Within our 80 iron ore–tagged pieces, Pilbara items are increasingly about logistics and debottlenecking rather than new greenfield mines, suggesting operators see export infrastructure like the Port of Dampier cargo wharf as the main lever to lift effective supply in Western Australia.
Sustained record monthly throughput at Pilbara Ports raises the bar for future expansion studies: any additional iron ore volumes from joint developments in the region will likely need either incremental berth and stockyard upgrades at Dampier or a re-optimisation of vessel queues to avoid congestion-driven demurrage costs.
