Special Issue Information

Dear Colleagues,

Since our cave-dwelling ancestors first tamed the power of fire, the development and utilization of new energy resources has always been a crucial part of human activities. The issue of how to fulfil global energy demands while mitigating the adverse impacts of climate change has attracted significant attention and is of great concern. After continuous exploration and research, offshore renewable energy resources have demonstrated their potential as a promising substitute for fossil fuels. For the floating wave–wind energy converter plants, wind turbines and wave energy converters can share a single set of power transmission systems and grid-connection equipment, significantly reducing power transmission costs and equipment construction costs. The joint development of offshore wind and wave energy can drive the iterative upgrading of wave energy development technologies with the relatively mature floating wind turbine technology. In addition, relevant engineering vessels and professionals can be shared during the construction and subsequent operation and maintenance of the power plant, thereby reducing engineering construction and maintenance costs.

This Special Issue aims to collect papers that present recent research advances related to all aspects of floating wave–wind energy converter plants. Topics of interest for publication include, but are not limited to, the following:

  • Joint development of wind and wave energy;
  • Innovative concepts and technologies;
  • Multi-body hydrodynamic modelling and simulations;
  • Coupled dynamics and control;
  • Prediction of extreme response and loads on floating structures;
  • Structural design of floating wave–wind energy converters;
  • Model testing of floating wave–wind energy converter;
  • AI-technology applications in floating wave–wind energy converter;
  • Nonlinear and viscous effects on hydrodynamic performance.

To reduce the cost of offshore wind and wave power, an innovative combined wind–wave energy generation system constituting of a 15 MW semi-submersible floating offshore wind turbine (FOWT) and four torus-type wave energy converters (WECs) is proposed. A wholly coupled numerical model of aero-hydro-elastic-servo-mooring was built to evaluate the mooring line and motion dynamics of this novel combined system. Additionally, a practical mooring optimization framework is proposed with the Latin Hypercube sampling method, Kriging model, and the combined optimization techniques of the Genetic Algorithm and Gradient Algorithm. The optimization results demonstrate that the optimized mooring scheme satisfies all the strict constraints, validating the effectiveness of the optimization method. Moreover, the hydrodynamic characteristics of the combined system and the effects of the WECs on the mooring system under both rated and extreme conditions are discussed, including changes in time-series mooring tension, power spectral density, and statistical characteristics. The research findings provide a reference for the further development and optimization of this novel combined system, contributing to the efficient utilization of offshore renewable energy.
