By the beginning of 2018, U.S. eastern states committed to a pipeline of 8,200 MW of offshore wind to be built over the next decade. At this scale, investments in U.S. infrastructure will be justified. Drawing on the experience and engineering efforts of two experts in this area, this webinar recording provides insights into construction of vessels and ports to prepare for the planned build-out of U.S. offshore wind farms.
First, Karel Wagner of GustoMSC draws on the company’s expertise in design and engineering of wind turbine installation vessels which have installed the majority of offshore wind turbines and foundations erected in Europe to date. Wind turbine installation jack-ups are the solution of choice in Europe due to their efficient, flexible and robust characteristics. In the U.S. the Jones Act, port restrictions, supply chain limitations, growing turbine sizes and relatively large water depths are specific aspects that need to be addressed. Mr. Wagner will discuss some of the key parameters driving the design of a wind turbine installation jack-up in order to understand what suitable U.S. installation jack-up solutions may look like.
The second part, by Willett Kempton, describes the result of a multi-contractor, DOE-sponsored engineering study that developed an innovative concept of building turbine structures in port, from subsea structure up to the nacelle. The complete turbine and foundation are carried by a DP2 heavy lift crane vessel in one piece and placed on the sea floor without jacking up. The vessel and port can be designed to optimize this approach. With this method, most of the construction activity and labor are completed in port, which reduces cost and elapsed time of construction.
