Abstract

An optimisation model is proposed for scheduling the decommissioning of an offshore wind farm to minimise the total cost which is comprised of jack-up vessel, barge (transfer) vessel, inventory, processing, and on-land transportation costs. This paper also presents a comprehensive review of the strategic issues relating to the decommissioning process and scheduling models that have been applied to offshore wind farms. A mathematical model using mixed integer linear programming (MILP) is developed to determine the optimal schedule considering several constraints such as the availability of vessels and planning delays. As the decommissioning problem is challenging to solve, a matheuristic approach based on the hybridization of a decomposition approach and an exact method is also proposed to find the best solutions for the problems. A set of computational experiments has been carried out on two datasets to assess the proposed approaches.
