Acquire optimal conceptual and front-end engineering (FEED) studies. Our experts ensure the right solution for your design, whether it's and oil & gas platform or an offshore wind jacket.

Conceptual design & feasibility studies

Choosing a conceptual design that will both support the topside and sustain environmental forces and impact, is vital to ensure a long and reliable service life.

Several jacket designs are evaluated, including monotowers, tripods and 4/8-legged, either launched or lifted. We evaluate the overall dimensions, bracing arrangement, number and size of piles, all of which are highly dependent on topside size and weight as well as water depth. In-place conditions are also analysed. 

The results from the concept phase includes a recommendation of jacket type, including weight reports, cost estimates and conceptual drawings. When considering cost efficiency, practicality and endurance of the jacket, we focus on finding the solution that is the most suited to your needs.

Front-end engineering design (FEED) studies

Once a concept is determined, we move over to front-end engineering design. The FEED study comprises of more detailed analyses and reports such as the ones listed further below, relevant to either fixed platforms or floating platforms.

  • Design drawings describing the structure:
    • main elevations and frames
    • appurtenances
    • supports of risers
    • j-tubes and conductors
    • pile clusters and mudmats
    • piles
    • lift points or launch runners
    • and more
  • Interface drawings towards topside and subsea
  • Layout drawings for appurtenances
  • Conceptual drawings for installation aids:
    • buoyancy tanks
    • guides and bumpers
    • bollards
  • Conceptual drawings of walkway, access platforms, rigging platforms, ladders
  • Installation and transportation drawings
  • Documentation reports covering the Operation phase (ULS, ALS, FLS), the transport and installation phases (ULS, FLS)
  • Fabrication schedule and plan
  • Weight and material take off

In addition to the In-place conditions and boat impact analyses, other phases such as load-out, transportation and installation are evaluated. In the delivery, weight reports, cost estimates and drawings may be included.
