Abstract

In this article we examine the research question ‘How cost forecast equations for offshore wind turbine main components can improve the portfolio decisions from Product Portfolio Management (PPM)?” by an extensive literature review of product portfolio decisions within PPM in the wind industry. In addition, two key experts from a leading offshore wind turbine OEM have been interviewed to answer this question and the method of qualitative content analysis as outlined by Mayring has been used to analyze the interviews and interpret the findings. It was analyzed how portfolio decisions for future offshore wind turbines are made and how future turbine costs are estimated. Therefore, this paper provides the scientific foundation by presenting the status quo of how PPM makes portfolio decisions for offshore wind turbines and with it how the future cost of offshore wind turbines are estimated. Aiming to use the presented results in future research in order to create accurate cost forecast models for the turbine main components and with it the creation of an overall turbine CAPEX scaling model.
