Decommissioning regulations for offshore renewable energy facilities require that all facilities be removed and the seafloor cleared of all obstructions at the end of the life of the lease. In this chapter we provide an overview of the expected workflows and stages of decommissioning that are likely to arise for offshore wind farms. We begin with background information about the Energy Policy Act of 2005 and comparisons between offshore oil and gas facilities and wind decommissioning. When offshore wind decommissioning programs are executed, they will have many similarities with the oil and gas industry as well as some significant differences. An understanding of oil and gas decommissioning markets informs our expectations of the conditions expected to develop. Decommissioning regulations are specified and expected workflows are described. An alternative method for turbine removal is proposed which, if feasible, may significantly reduce decommissioning cost. We conclude by describing the exposure and liability of the parties involved.
