6 FAQs about [Wind turbine generator foundation construction]

What is a wind turbine generator foundation?

Wind turbine generator (WTG) foundations are estimated to represent approximately 25% of the balance of plant (BOP) cost of a wind farm. The foundation supports a multimillion-dollar asset, without which revenue would be impossible, yet this asset is mainly invisible and its operational health unknown.

What type of foundation does a wind turbine use?

The majority of wind turbines in the U.S. today stand on a spread footing foundation consisting of cast-in-place reinforced concrete. This type of foundation relies on the strength of the concrete, the weight of the turbine, and soil backfill to provide stability and adequately transfer loads to the underlying soil and rock.

Do wind turbine tower foundations need to be more innovative?

Phu Lac wind farm Increasing wind turbine and tower sizes and installations in deeper waters have clearly demonstrated a need for more innovative and cost-effective foundations. This paper summarizes basic relevant foundation and geotechnical issues for onshore and nearshore wind turbine tower foundations.

What are the different types of wind tower foundations?

For onshore wind turbine tower, there are basically 5 common types of wind tower foundations: the shallow mat extension, the ribbed beam basement, the underneath piled foundation, the uplift anchors and the new type. For each type, it can be both in round shape or in octagon shape. The diameter ranges from 15m to 22m.

Why is Foundation dynamics important in the design of an offshore wind turbine?

Foundation dynamics is an important consideration in the design of an offshore wind turbine. As the offshore wind turbine rotates, the blades travel past the tower creating vibrations to which the offshore wind turbine is sensitive.

How do turbine foundations work?

The design of the turbine foundations take into account the normal operating and extreme load conditions imposed by the turbine. The standard method of providing support to the turbine is by way of a concrete gravity base, typically of a cir-cular shape to account of the variable directional nature of the design loadings.
