What is the Impact of Seabed Conditions?

Poor conditions on the sea bed can have a very negative impact

Eirik Byklum, Statoil, has commented that:

"developers have learnt the hard way that poor conditions on the sea bed can have a very negative impact – they are much more aware of this and its cost implications"

How important are seabed conditions for your offshore wind business?

Alongside distance to shore, water depth, and wind conditions, seabed consistency has a major impact on wind farm design, in terms of turbine and foundation selection, size of the farm, and the project logistics for installation and O&M. In turn, seabed conditions have a direct impact on both CAPEX and OPEX costs.

If, for example, mobile seabed conditions are found where an offshore project is planned, the impact can be disastrous, as has been seen in recent incidences of delayed and cancelled projects. In contrast, a thorough understanding of seabed conditions has a strong positive impact on project finances. As Byklum explains:

"the layout of the turbines is something that can have a great deal of impact on productivity. It draws upon various variables, notably the seabed beneath and the direction from which the wind is coming"

If optimum positioning can be established considering both wind resource assessment and seabed assessment, foundation design will be cheaper and risks will be reduced, contributing to the overall lowering of the levelised cost of energy (LCOE) that the industry is striving for.

GeoSea has produced a case study, Assessing the Implications of Working Areas of Complex Soil, which looks at some of the challenges of complex soil conditions.

It includes an overview of GeoSea's high-profile projects (DOTI's Alpha Ventus, Trianel's Borkum West II, Dong's Borkum Riffgrund I, EnBW's Baltic II), and a look at innovative solutions to working in areas of complex soil.

If seabed conditions have an impact on your business, this presentation should be interesting for you.
