Offshore • Offshore Wind Turbine, East Coast, United States: project manager responsible for the final design and installation of the first offshore wind turbine constructed in the United States. Project is currently under development and consists of the design and installation of a 5 megawatt wind turbine founded in an offshore environment. Detailed geotechnical and structural analysis are being performed by Parsons Brinckherhoff to account for the static loads and dynamic operation of the turbine, coupled with the hydrodynamic loading imparted by waves and currents. Parsons Brinckerhoff has provided conceptual engineering for various substructure and foundation types and has advanced the final design of the preferred alternative. Primarily governed by dynamic processes and loading cases, such as driving stresses and fatigue, detailed finite element analyses have been performed to estimate cumulative fatigue damage to the structure. Grouted connections, previously noted as problematic areas of wind turbine substructure design based on European experience, have been analyzed using LSDyna to determine any fatigue-related design issues during operation. Hydrodynamic loading has been developed in time series based on AQWA modeling from nearby buoys, and verified by recently deployed AWAC buoys. An extensive offshore geotechnical engineering investigation utilizing CPTs, soil borings and laboratory testing was implemented to define subsurface conditions, critical for determining lateral soil spring values and for analyzing pile drivability. At completion, the project is expected to be the first offshore wind turbine constructed in the United States.
