Diaz, H.M. and Guedes Soares, C. (2023), Cost and financial evaluation model for the design of floating offshore wind farms, Ocean Engineering, Vol. 287, 115841

A cost and financial evaluation model is proposed for the floating farm designs. The model evaluates the cost of the offshore farm attending the required capacity, technical aspects, and technology implemented, among others. The costs involved in the different phases of farm construction are studied. The main equations developed for the model construction are simplified and presented in this document. This study presents a comparison of several financial indicators for the following floating concepts: Spar-Buoy (TELWIND), Tension-Leg-Platform (CENTEC-TLP) and Semi-Submersible (SATH). The model is applied to a floating farm composed of thirty-four 10 MW turbines in a Life Cycle Analysis perspective. The model allows the determination of the optimal floating platform for a site and identifies the optimal solution for a floating farm based on the economic and financial aspects associated.
