A Mixed-Integer Formulation to Optimize the Resupply of Components for the Installation of Offshore Wind Farms

摘要

Over the last decade, offshore wind energy has become a viable source of sustainable energy. During the installation of offshore wind farms, the dimensioning of related base ports became increasingly important. Base ports act as central logistics hubs for the installation and, thus, need to provide sufficient space and equipment to store and handle required components. Thereby, current developments tend to larger and heavier components as well as to an increase in simultaneously occurring installation and decommissioning projects. This article proposes a Mixed-Integer formulation for the optimization of supply deliveries to the base port. Moreover, it presents an example of this formulation’s integration with an optimization of the base port capacity and, furthermore, a simulation study on the effects of different resupply cycles on the efficiency of installation projects. Results show that the resupply cycle has a minor influence on the project’s efficiency but highly affects the base port capacity.
