Operational expenditure (OPEX) is one of the major contributors to the levelized cost of energy (LCoE) for offshore wind farms. To assess different solutions and select the best ones, good models for maintenance and logistics decision support are required. This chapter provides an overview of, and a brief introduction to, operation and maintenance (O&M) modelling for offshore wind farms, including transport and logistics for O&M. It provides an overview of O&M modelling for offshore wind farms. The primary focus is on the application of offshore wind O&M models for decision support. An overview of the current status in O&M modelling for offshore wind farms is presented. The chapter focuses is first on strategic O&M simulation models, and discusses models for selected optimization problems. It outlines the general differences between optimization and simulation models. The decision support tools and concepts developed in NOWITECH and related projects include models on both the strategic, tactical and operational level
