Coupled Dynamics and Vibration Control in Integrated Floating Wind and Wave Energy Structures

Project description

Integrated wind and wave energy harvesting

Supported by the Marie Skłodowska-Curie Actions programme, the WAVES project intends to design and develop a multibody model to simulate the coupled dynamics of an integrated floating offshore wind turbine (FOWT) and wave energy converter (WEC) system that can simultaneously harness offshore wind and wave energy. To do so, the model will incorporate aerodynamics, hydrodynamics and structural dynamics computational modules. First, it will study how the FOWT, WEC and surrounding flow fields interact with each other and investigate the non-linear vibrations of the system. It will also carefully evaluate the system’s serviceability and safety performance under both operational and extreme conditions. Finally, it will design novel control methods to effectively reduce vibrations within the system.

Objective

This project focuses on integrating floating offshore wind turbines (FOWT) with wave energy converters (WEC) to simultaneously harness offshore wind and wave energy. The specific objectives are: (1) to gain an understanding of the interactions between the FOWT, WEC, and surrounding flow fields, and to explore the nonlinear vibrations of the FOWT-WEC system; (2) to thoroughly assess the serviceability and safety performances of the FOWT-WEC system under both operational and extreme conditions; and (3) to develop innovative vibration control techniques aimed at effectively reducing responses of the FOWT-WEC system.
To achieve these objectives, a multi-body model will be developed and integrated with aerodynamics, hydrodynamics, and structural dynamics computational modules to simulate the coupled dynamics of the FOWT-WEC system. Optimal designs for the WECs in terms of numbers, shapes, and configurations will be conducted to maximize energy generation and reduce wave loads, with a thorough evaluation of the system’s serviceability and safety. Given the space constraints and changes in structural dynamic characteristics, a novel pendulum inerter-based nonlinear energy sink will be designed to mitigate excessive vibrations within the FOWT-WEC system. The project will also incorporate comprehensive outreach and educational initiatives, including tutorials in STEM courses, engaging graduate and undergraduate students in research, and offering seminars and webinars to stakeholders.
The research outcomes will contribute significantly to the creation of a new integrated wind and wave energy harvesting paradigm with the consequent reduction of energy costs on both national and global levels. This fellowship will provide substantial support in achieving the researcher’s future academic and professional goals.
