Última Advancing IEC standardisation and certification for tidal energy convertors ArchiMer Scheijgrond, Peter; Southall, Anna; Bittencourt, Claudio; Davies, Peter; Mathys, Pieter; Germain, Gregory; Geertzen, Martijn. Conformity assessment can mitigate technical and financial risks of technologies, which in turn attracts finance and encourages international trade. As marine energy is an emerging industry, international standards are yet to be consistently adopted and a conformity assessment system is currently under development Tipo: Text Palavras-chave: Marine energy; Tidal energy; Standards; Certification; Experimental trial; Test protocol; IEC; IECRE; Conformity assessment; Risk mitigation. Ano: 2018 URL: https://archimer.ifremer.fr/doc/00599/71136/69450.pdf A comprehensive assessment of turbulence at a tidal-stream energy site influenced by wind-generated ocean waves ArchiMer Thiébaut, Maxime; Filipot, Jean-francois; Maisondieu, Christophe; Damblans, Guillaume; Duarte, Rui; Droniou, Eloi; Chaplain, Nicolas; Guillou, Sylvain. Velocity measurements collected by an upward-looking acoustic Doppler current profiler were used to provide the first study of ambient turbulence in Alderney Race. Turbulence metrics were estimated at mid-depth during peak flooding and ebbing tidal conditions. The dissipation rate ε and the integral lengthscale (L) were estimated using two independent methods: the spectral method and the structure function method. The spectral method provided ε and (L) estimates with standard deviations twice lower than that obtained from the structure function method. Removal of wave and Doppler noise-induced bias when estimating the dissipation rate was shown to be a crucial step in turbulence characterization. It allowed for a significant refining in (L) estimates... Tipo: Text Palavras-chave: Turbulence; Tidal energy; Wave; Doppler noise; ADCP; Alderney Race. Ano: 2020 URL: https://archimer.ifremer.fr/doc/00592/70394/68478.pdf Dynamic behaviour of an undulating membrane tidal energy converter under wave and current loading ArchiMer Träsch, Martin; Delacroix, Sylvain; Déporte, Astrid; Drevet, Jean-baptiste; Gaurier, Benoit; Germain, Gregory. The dynamic behaviour of an undulating tidal energy converter under wave and current loadings is studied. Therefore, a small scale prototype of a damped pre-stressed undulating membrane is tested in a wave and current recirculatory tank. The membrane’s dynamic profile and hydrodynamic forces are measured synchronously with the surface elevation for both regular and irregular waves in current direction. Spectrum analysis reveals that the response to wave loading depends on the wave frequency and is reduced by damping-type power take-off. Coupling between the wave frequency and the main undulation frequency or its harmonics is also observed. An increase of 30% of the forces must be foreseen in case of wave condition in the tested range.
