    Port Hedland bypass channel: design and dredging notes for port engineers

    Port Hedland bypass channel: design and dredging notes for port engineers

    First reported on Australian Mining

    30 Second Briefing

    Dredging contractor Jan De Nul Australia has secured a $50 million Western Australia Government-backed contract from Pilbara Ports to construct the new Zone 5 Bypass Channel at Port Hedland. The channel is designed to divert traffic from the main shipping channel used by iron ore carriers, improving vessel separation and reducing congestion in one of the world’s highest-tonnage bulk export ports. For marine and port engineers, the works will involve large-scale capital dredging in highly tidal, sediment-laden conditions, with implications for berth access, navigation risk and cyclone-resilience planning.

    Technical Brief

    • Contract value is $50 million, funded through the Western Australian state budget allocation.
    • Jan De Nul Australia engaged as marine dredging contractor under Pilbara Ports’ capital works programme.
    • Works form part of Pilbara Ports’ Zone 5 development, expanding marine infrastructure at Port Hedland.
    • Government framing emphasises improved operational resilience of port access during adverse weather and disruption events.
    • Channel works expected to support more predictable shipping windows, easing tidal and congestion-related schedule risks.
    • Project is positioned as a key enabler for long-term export growth from the Pilbara supply chain.

    Our Take

    Pilbara Ports’ recent throughput data in our coverage – including the 71.2 Mt record in December 2025 and 65.9 Mt in April 2026 – underlines that any new bypass channel at Port Hedland is effectively a debottlenecking and resilience play for one of the world’s highest-volume bulk export hubs.

    With no commodity specified but Port Hedland dominating iron ore exports in our database, the bypass channel will likely be scrutinised by major miners as a safety and reliability upgrade that could reduce vessel interaction risk and support higher peak shipping windows during cyclone recovery periods.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
