Independent marine geoscience specialists.

Stratasea is an independent marine geoscience consultancy supporting offshore wind, interconnector and subsea cable projects.

The company was founded on over a decade of simple observational experience that ground risk is one of the largest sources of cost and schedule uncertainty offshore, and most of it is shaped by decisions made long before anything is installed.

Being independent matters here. We have no vessel to keep busy and no design scope to protect, so the advice you get is shaped only by what your project needs.

How we work

Stratasea combines a geotechnical core with a trusted network of senior specialists in other geoscience disciplines, drawn on as each project requires. It means you get the right expertise for the problem, scaled to the task, without carrying the overhead of a large organisation.

What you get

Client-side experience shapes how we work. We know what a project team is actually being asked to decide and when, so we focus on what matters at each phase. The aim is a clear, decision-ready understanding of the seabed and below: reducing ground risk from early development through construction and into operations.
