IET Renewable Power Generation, Volume 15, Issue 14, Page 3220-3231, 26 October 2021., 2021 Abstract A mixed time‐domain/frequency‐domain method is proposed for modelling dense wave energy converter (WEC) arrays with non‐linear power take‐off (PTO). The model is based on a harmonic balance method which describes the system response in the frequency domain, while evaluating the non‐linear PTO force and solving the system equations of motion in

IET Renewable Power Generation, Volume 15, Issue 14, Page 3243-3254, 26 October 2021., 2021 Abstract Mooring systems are a significant capital cost of a floating wave energy converter and their premature failure negatively impacts operational costs. Excessive peak loads and accumulated fatigue damage can lead to failure, so these factors are cost drivers in wave energy converter design.

LMI‐based passivation of LTI systems with application to marine structures
IET Renewable Power Generation, Volume 15, Issue 14, Page 3424-3433, 26 October 2021., 2021 Abstract Due to the inherent relevance of passive (physically representative) models for control, state‐estimation, and motion simulation in the field of marine systems, in this paper, an optimisation‐based approach to passivation of linear time‐invariant (LTI) systems is proposed with application to physically consistent dynamical modelling of marine ...

A review of wave energy technology from a research and commercial perspective
IET Renewable Power Generation, Volume 15, Issue 14, Page 3065-3090, 26 October 2021., 2021 Abstract Although wave energy prototypes have been proposed for more than 100 years, they have still not reached full commercialisation. The reasons for this are varied, but include the diversity of device operating principles, the variety of onshore/nearshore/offshore deployment possibilities, the diversity of the wave climate at various potential ...

IET Renewable Power Generation, Volume 15, Issue 3, Page 548-561, February 2021., 2021 Abstract A methodology to automate the sizing of a wave energy converter (WEC) is presented. The preliminary design of WEC geometry is addressed as a mathematical program by means of a meta‐heuristic optimisation, which includes as key aspects the use of a multi‐objective differential evolutionary (DE) algorithm and the implementation of a stochastic ...

Proceedings of 18èmes Journées de l'Hydrodynamique, 2022 Second-order wave loads on a floating structure may excite resonance phenomena, such as slow-drift or springing, at the natural frequencies of the floating structure. Therefore, taking into account the response of a floating offshore wind turbine (FOWT) platform under non-linear wave loads is of paramount importance for its design.This paper presents ...

An efficient optimisation tool for floating offshore wind support structures
Energy Reports, 2022 Floating offshore wind turbines (FOWTs) are a rapidly developing technology, but still, need to gain economic competitiveness to obtain market acceptance. The reduction of the structural cost of the floating platform represents one of the main targets to

Energies, 2017 Wave Energy Converters (WECs) need to be deployed in large numbers in an array layout in order to have a significant power production. Each WEC has an impact on the incoming wave field, by diffracting, reflecting and radiating waves.

, 2021 Boundary Element Method (BEM) solvers are extensively used to obtain the hydrodynamic coefficients required to model hydrodynamic forces in floating marine structures. BEM solvers require the discretization of the submerged device surface as a mesh to compute the hydro-dynamic coefficients as radiation damping and added mass, response amplitude ...
