On building physics-based AI models for the design and SHM of mooring systems
(2023-01-01)
Expert systems in industrial processes are modelled using physics-based approaches, data-driven models or hybrid approaches in which however the underlying physical models generally constitute a separate block with respect ...
Faulty wind farm simulation: An estimation/control-oriented model
(2023-01-01)
A large percentage of the electricity generation cost of wind turbines (WTs) is related to the operation and maintenance of the WTs. To reduce such costs, fault detection and isolation (FDI) and fault tolerant control (FTC) ...
Technology-Agnostic Assessment of Wave Energy System Capabilities
(2022-04-01)
Developing new wave energy technologies is risky, costly and time-consuming. The large diversity of concepts, components and evaluation criteria creates a vast design space of potentially feasible solutions. This paper ...
Numerical Approaches for Loads and Motions Assessment of Floating WECs Moored by Means of Catenary Mooring Systems
(2022)
Technologies for harvesting offshore renewable energy based on float- ing platforms, such as offshore wind, wave and tidal energies, are currently being developed with the purpose of achieving a competitive cost of energy. ...
Frequency domain modelling of a coupled system of floating structure and mooring Lines: An application to a wave energy converter
(2021-01-15)
Floating structures for single offshore renewable energy devices, i.e. wave energy converters, tend to be significantly smaller than those of the traditional offshore industry and the interaction between floater motions ...
Review of systems engineering (Se) methods and their application to wave energy technology development
(2020-10-01)
The design of effective and economically viable wave energy devices involves complex decision‐making about the product based on conceptual design information, including stakeholder requirements, functions, components and ...
A comparison of numerical approaches for the design of mooring systems for wave energy converters
(2020-07-01)
This paper analyses the numerical outcome of applying three different well-known mooring design approaches to a floating wave energy converter, moored by means of four catenary lines. The approaches include: a linearized ...
Small scale experimental validation of a numerical model of the HarshLab2.0 floating platform coupled with a non-linear lumped mass catenary mooring system
(2020-03-15)
When focusing on mooring system numerical modelling, the efforts are focused on validating models that increase the accuracy and maintain the computation time under reasonable limits. In this paper an approach for modelling ...
Reducing variability in the cost of energy of ocean energy arrays
(2019-09)
Variability in the predicted cost of energy of an ocean energy converter array is more substantial than for other forms of energy generation, due to the combined stochastic action of weather conditions and failures. If the ...
Hydrodynamic identification of NAUTILUS FOWT platform from small scale tests
(2019)
A small-scale tank test campaign of the NAUTILUS offshore wind floating semisub-mersible platform was held at the Ifremer Deep Water Basin within the framework of the MaRINET 2 project. The support structure consists in ...
