Port Hedland Zone 5 Bypass Channel

Port Hedland's Zone 5 Bypass Channel has moved from a 2021 risk-mitigation design through offshore geotechnical work, environmental and continuity planning, and a June 2026 A$50 million award to Jan De Nul Australia. The public design allows up to 800,000 cubic metres to create a -11.5 m Chart Datum route and place material at SG7C, but permit approval, mobilisation, accepted geometry and demonstrated reduced-capacity transit remain open.

Project anatomy

Contract scope and delivery roles

Client / authority
Pilbara Ports
Delivery parties
Jan De Nul Australia
Contract route
Pilbara Ports awarded an A$50 million capital-dredging contract to Jan De Nul Australia on 22 June 2026 after navigational simulations, environmental studies and a 2025 offshore geotechnical campaign. The reviewed award records do not publish the tender number, bid field, contract duration, final measured quantity, named dredging plant or separate hydrographic and navigation-system packages.
Execution window
The owner expects dredging to start in September 2026. The October 2021 proposal content document used a five-week construction assumption and 50-year operating period, but the award record gives no completion date; the earlier assumption should not be converted into a current contractual duration without an owner or contractor programme.
Works package
The environmental envelope defines a 432-hectare navigation-channel area including a 50-metre buffer, a -11.5 m Chart Datum design depth plus up to 1.0 metre of over-dredge, and up to 800,000 cubic metres across a 162-hectare disturbance footprint. A TSHD is anticipated, with a CSD possible for consolidated spots, and material is proposed for the 282-hectare SG7C sub-area of Spoil Ground 7 in Commonwealth waters. Future maintenance would require incorporation into the port's maintenance sea-dumping permit.
Marine interfaces
The bypass sits beside a steep-edged reach of Port Hedland's single 42-kilometre channel, where very large bulk carriers move in tidal convoys. Its value depends on work-vessel separation, VTS controls, passing lanes and refuge areas, dredging plume and fauna controls, disposal-site release, aids and hydrography, Harbour Master procedures, salvage-command handoff and the ability to move controlled traffic at reduced capacity when Zone 5 is obstructed.
Commercial evidence boundary
The award is a credible capital-dredging commitment and future fleet-demand signal, but the public maximum volume is an environmental envelope rather than a bill quantity. The package's economic value is continuity rather than added headline capacity: it becomes real only after regulatory closure, final geometry, nautical acceptance and an approved activation procedure support vessel transit around a blocked main channel.

Open this project in the Change Log

Pilbara Ports awarded the A$50 million dredging contract

Jan De Nul Australia became the named delivery contractor and the owner stated a September start target. The award left federal permit grant, plant mobilisation, final quantity, completed dredging, accepted geometry and operational release ahead.

Source

EPA WA decided not to assess the proposal under Part IV

The state referral exited the Part IV assessment pathway after preliminary examination. That decision was not a federal sea-dumping permit, dredging approval, notice to proceed or construction acceptance.

Source

Pilbara Ports lodged federal sea-dumping application SD2026-4091

The application sought a two-year permit for loading and dumping up to 800,000 cubic metres from the capital works. The current federal register records the application but does not list it among granted or refused permits.

Source

The final environmental review documented the execution envelope

The review carried the channel, dredging, disposal, monitoring and marine-fauna controls into the referral record. It defined a maximum environmental envelope, not the awarded bill quantity or completed as-built works.

Source

The salvage plan linked bypass activation to incident command

The port's response plan tied slow-speed passing and bypass activation to Harbour Master approval, salvage stabilisation and business-continuity sequencing. The procedure is planning evidence, not proof that the unbuilt route is available.

Source

Pilbara Ports issued the offshore geotechnical investigation notice

Ocean Driller II and support craft were scheduled for approximately three weeks of boreholes and seismic work from 13 September under VTS controls. Investigation reduced design uncertainty but did not constitute capital dredging.

Source

The proposal fixed the first public channel and material envelope

Pilbara Ports defined a -11.5 m Chart Datum route, one-metre over-dredge allowance, up to 800,000 cubic metres and SG7C placement as a risk-mitigation concept. At that stage approvals, procurement and construction remained unresolved.

Evidence gap

What remains unverified

Outstanding evidence

  • September mobilisation notice, dredging plant, and marine traffic controls
  • Final bypass geometry, design depth, and measured dredging quantity
  • Dredged-material route and environmental monitoring performance
  • Completion hydrography, navigational aids, and formal channel acceptance
  • Contingency procedures and evidence of usable reduced-capacity transit
