Saeidtehrani, S. (author), Lavidas, G. (author), Metrikine, A. (author)The process of finding values of extreme waves and their impacts on wave energy converter (WEC) responses, depends on both wave resources and WEC dynamic characteristics. A wide range of waves can influence the reliability of operation and survivability of a WEC. In this paper, a methodology is described to find specific values of wave heights...conference paper 2022

Lavidas, G. (author), Loukogeorgaki, Eva (author), Michailides, Constantine (author), Chatjigeorgiou, Ioannis K. (author)Wave Energy Converters (WEC) have seen a wide variety of innovations capable to harness the vast untapped energy source of the seas. This wide range of WECs often has varied applicability and power production capabilities, making the selection of a device overwhelming. These uncertainties are increased when<br/>considering the interactions and...conference paper 2021

van Vlijmen, Bruis (author), Goudswaard, Reinier (author), Boere, Remco (author), Schneider, Thomas (author), Polinder, H. (author), Lavidas, G. (author)It is expected that several identical Point Absorber Wave Energy Converters (PAWECs) will be arranged in arrays to form a Wave Energy Farm. One of the key challenges in designing such a WEC array is their spatial configuration, as the WECs in the farm interact hydrodynamically with each other. This study focuses on different potential PAWEC...conference paper 2019

Masturi, L.M. (author), Hendrikse, H. (author), Jarquin Laguna, A. (author), Metrikine, A. (author)The vertical axis pendulum is a type of point absorber device which can absorb wave energy from a width exceeding the physical width of the device. Mechanical power is harvested from the rotation of the pendulum, in which the pivot point is directly connected to the generator. In this paper, a new concept of the vertical axis pendulum device is...conference paper 2019

Loukogeorgaki, Eva (author), Michailides, Constantine (author), Lavidas, G. (author), Chatjigeorgiou, Ioannis K. (author)In this paper, we determine optimum layouts of a cluster of oblate spheroidal heaving point absorbers in front of a wall, that maximize the annual averaged power absorbed by the cluster, while satisfying specific spatial constraints. An iterative optimization process is developed by coupling a hydrodynamic model with a genetic algorithms solver....conference paper 2021

Lavidas, G. (author), De Leo, Francesco (author), Besio, Giovanni (author)The option to have an WEC integrated breakwater at the port of Genoa ensures that the port will protect the area from harsh incoming waves, but also contribute towards the port decarbonization. However, for the solution to be viable, a first layer analysis must estimate its profitability. This works uses a long-term high fidelity wave numerical...conference paper 2023
