Offshore Wind Farm

The owner is planning to construct an initial phase of offshore wind power consisting of six turbines having a combined capacity of about 20MW. The turbines are to be located about 2.8 miles offshore in about 40 feet of water. The sea bed sub-surface conditions consist of hundreds of feet of unconsolidated sandy and silty soils. Langan's role is to provide geotechnical consultation and QC supervision of the geotechnical subsurface investigation program. Langan provided recommendations for the subsurface investigation for the turbines and the cable; this included drilling and probe methods, in-situ testing, and a laboratory testing program. In addition, Langan is providing archeological consultation related to geophysical surveys of the sea bed and geomorphological review of sediment cores.
