    Benestad–Nexans connector for floating wind: design and layout notes for engineers

    Benestad–Nexans connector for floating wind: design and layout notes for engineers

    First reported on Geoengineer.org – News

    30 Second Briefing

    A new DNV-approved subsea connector from Benestad and Nexans targets faster, safer connection of dynamic power cables for floating offshore wind farms in open sea conditions. The wet-mateable, high-voltage unit is designed for repeated connection and disconnection without cable cutting, reducing offshore vessel time and exposure of technicians to heavy lifts and harsh weather windows. For geotechnical and offshore designers, the technology could ease maintenance strategies, simplify array reconfiguration, and influence layout decisions for deep-water floating foundations.

    Technical Brief

    • Wet-mate design allows ROV operation, reducing diver-based intervention and associated safety exposure.
    • Qualification testing included repeated mate–demate cycles under pressure to simulate deep-water operating conditions.
    • Mechanical latch and keying features are designed to prevent misalignment and partial engagement during mating.
    • Pressure-balanced oil-filled (PBOF) or similar insulation concepts limit seawater ingress risk at high voltage.
    • For future floating arrays, such connectors could support modular “plug-and-play” replacement of faulty floaters or cables.

    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.
