“…The environmental conditions that usually hinder the majority of the offshore operations concern stochastic variables such as wind speed, wave height and wave period. The wind and wave influence on the uncertainty of the operational window (i.e., the period in which offshore works can be executed) is a well-known problem and has been extensively studied for installation and maintenance activities of offshore wind farms (Stålhane, Vefsnmo, Halvorsen-Weare, Hvattum, & Nonås, 2016;Kikuchi et al, 2009;Martin, Lazakis, Barbouchi, & Johanning, 2015;Leontaris, Morales-Nápoles, & Wolfert, 2016). Probabilistic models have been developed to cope with uncertainties of the duration of the operational windows and its effect on offshore infrastructural assets planning (time and costs).…”

“…A numerical example is illustrated to validate the model. Stalhane et al (2016) determine the optimal fleet size and mix of vessels to support maintenance activities at offshore wind farms. A two-stage stochastic programming model is proposed where uncertainty in demand and weather conditions are considered.…”

“…Constraint (22) forces f ms to one if task m is completed within shift s and Constraint (23) forces f ms to zero if task m is not completed within shift s. Constraint (24) prohibits that a task m is performed during shifts after the task is completed.…”

“…A majority of these models use simulation tools to analyze O&M related costs, and the use of optimization models for analyzing O&M costs are limited. Halvorsen-Weare et al [20], Gundegjerde et al [21] and Stålhane et al [22] use optimization models to investigate vessel fleets and determine the optimal fleet size and mix for an offshore wind farm. These models can be used as support when deciding when and how many vessels to purchase or rent, addressing decisions on a strategic level for O&M in offshore wind farms.…”
