Description

In response to the growing global demand for renewable energy, the interest of deploying offshore wind turbines (OWTs) in cold climate regions is increasing. The high air density and good wind resources in cold climate regions offer promising prospects for OWTs’ development. However, to supply energy reliably to local communities, significant challenges posed by the remote and severe conditions of cold climates must be effectively addressed. In cold climates, the primary challenges for offshore wind turbines are icing and ice-structure interaction. A review of state-of-the-art research on prediction models for ice accretion and ice-induced loads is presented, including cold-weather packages and ice protection systems to combat icing, along with ice-breaking cones and tuned mass dampers (TMDs) for managing ice interactions, are necessary for OWTs. The present study points out critical knowledge gaps in OWTs deployment in cold climate regions and suggests directions for future research.
