Profile Lead Structural Engineer - Fixed Offshore Structures

Are you an engineer who can lead a team of structural engineers and monitor the progress and planning? Can you advise on technical matters in projects and function as a consultancy role towards clients?


For one of our clients, a Dutch engineering firm, we are looking for a Lead Structural Engineer - Fixed Offshore Structures. You will design concept-, basis-, and detail designs for fixed offshore structures with a focus on substructures. These substructures consist of jackets, tripods, monopiles, and transition pieces for the Offshore Wind Industry and Oil & Gas production facilities.


As Lead Structural Engineer, you will perform the necessary design analyses together with the team and studies with accompanying reports independently. You will also coach other engineers and on behalf of the company, you will be monitoring and discussing the project's progress with the Project Manager and with the client on occasion.


Tasks & responsibilities:

  • The complete structural design of substructures (jackets, tripods, monopiles, and transition pieces) for Offshore SubStations (OSS) including the transportation and installation thereof.
  • The complete structural design of topsides for OSS including transportation and installation thereof.
  • The design of transport and installation provisions such as lifting points, spreader frames, guides, bumpers, grillages, sea fastening, etc.
  • The design of secondary steel components such as working platforms, boat landings, Jtubes, cable hang-off clamps, anode cages, etc.
    • For the Offshore Oil & Gas market, you will engineer.
  • The design of platform components such as living quarters, (blast) walls, bridges, vent stacks, flarebooms, crane pedestals, helidecks, boat landings, riser clamps, bumpers, etc.
  • The design of platform modifications such as deck extensions & modifications for new or replacement of equipment.
  • The design of subsea structures such as wellhead protection frames, side tap protection structures, and PLEMS & PLETS.
  • The decommissioning engineering for topside and substructures.
  • Platform lifetime extension studies.
  • To deliver the designs, you will make global strength analyses consisting of:
    • Loadout, upending, lifting, transport, transport fatigue, installation/stabbing, onbottom/unpiled, in-place fatigue, vessel impact/collision, seismic, redundancy/pushover, lifetime extensions, foundation piles, pile drivability, and more.
  • You will also make detailed strength calculations for:
    • Welded connections, grillage and sea fastening, vessel/barge deck strength, nodes & joints (e.g., diamond plates), detailed buckling checks for shell structures, lifting points (e.g., padeyes & trunnions), rigging selection, weight, and center of gravity (CoG)/center of buoyancy (CoB) calculations, weight control reports, bolted connections, and more.
