- Worldwide experience
- Clarity over your project’s direction
Our typical approach to early-stage design
Wherever you are in your foundation design journey, we help you take your project forward.
By the end of the process, you’ll have a clear idea of the foundations you need, high-level costs, and your supply chain requirements.
01
Kick off
We familiarise ourselves with the work you’ve done to date, and agree next steps and required outcomes in a project brief.
02
Design
Using our experience and in-house design capabilities we evaluate all the options to assess feasibility and create cost estimates.
03
Plan
Alongside providing early-stage designs, we help you identify and mitigate key risks whilst supporting you with engagement of the supply chain.
Our early-stage design services
Early-stage design terminology varies across the industry. Whether it’s concept, Pre-FEED or FEED, we work with you to define and scope your project in your terms, to fit your requirements.

Site data assessment
We begin by collecting information about your proposed site, including wind, wave, and soil conditions. We also gather data on the turbines you’re planning to use.

Concept design
We use the assessment outputs to produce a suitable concept design. This takes into account technical characteristics, risks, costs, potential supply chain issues, and logistics. Your concept design provides valuable insights to shape project decisions, especially around fabrication, and transport and installation (T&I) methodologies.

Front-end engineering design (FEED)
Once your concept design is agreed, we produce your front-end engineering design (FEED). This will give you more detail on factors such as weight, manufacturing cost, and installation cost, to inform your business case.
