Abstract

Abstract

The present paper addresses newly developed finite elements that addresses the prediction of stresses in conductors of dynamic power cables applied for connecting offshore wind turbines to the grid. To describe relevant physical effects during all phases including manufacturing, installation, and operation, 3D analysis is required. As a result, the development has been based on beam and beam contact formulations that enhance computational efficiency. This is followed by a numerical study that serves several purposes; verification, shedding light on different aspects of conductor behavior, and providing sufficient detail to be applied as a reference example for other scholars. Good correlations have been found between the proposed models and other models either obtained from literature or by applying other software.
