Offshore Wind Substructure & Installation Engineering

Foundation and installation engineering for fixed and floating offshore wind: monopile and jacket substructure design to DNV-ST-0126 and IEC 61400-3, offshore substation platform structures, floating-platform mooring and station-keeping, and transport, sea-fastening and installation engineering for monopiles, transition pieces and WTIV operations. Positioned for India’s Gulf of Khambhat and Gulf of Kutch auctions and Asia-Pacific developers.

Offshore Wind Substructure & Installation Engineering

What you receive

  • Concept comparison: monopile, jacket, floating — by water depth, soil and turbine class
  • Substructure design: ULS/FLS/SLS to DNV-ST-0126, IEC 61400-3 and ISO 19902; pile driveability inputs
  • Offshore substation platform (OSP) structural design and T&I
  • Floating wind mooring and station-keeping analysis (DNV-ST-0119)
  • Transport, sea-fastening and installation engineering for monopiles, TPs and WTIV jacking
  • Third-party review of foundation design packages for developers and lenders

Transferable depth from oil and gas

Offshore wind substructures are offshore structures: the jackets, piles, sea-fastening, lifts and jack-up assessments that we deliver for oil and gas transfer directly, with the wind-specific loads and standards layered on. That is why our first wind scopes are the ones that look like our track record: transport and installation engineering, jacket and OSP structural design, and independent review for developers.

India and Asia-Pacific

India’s first offshore wind auctions off Gujarat and Tamil Nadu, and the growing Taiwanese, Korean, Vietnamese and Australian pipelines, need foundation design and installation engineering delivered at Asian rates and time zones. We deliver from Mumbai to developers, EPCI contractors and installation-vessel operators.
