Les énergies marines renouvelables répondent-elles au modèle d’économie de la fonctionnalité ? ArchiMer
Lalancette, Soazig; Le Floc H, Pascal; Le Gallic, Bertrand.
This article seeks to estimate the relevance of the service economy applied to marine renewable energy projects. This study is based on stakeholder contributions in public debate in Saint-Brieuc offshore wind farm project (France). We seek to analyze stakeholder perspectives through an application of a textual analysis on contributions (cahiers d’acteurs). Textual analysis reveals two main results, the first one turns to social and economic question with the impact on the territory, in particularly the employment and the training. The second issue concerns the energy efficiency of marine renewable technologies. For each of these issues, the discussion try to give a perspective regard to service economy theory and discuss about the relevance of service...

Génération de bases de données océano-météorologiques pour l'élaboration de climatologies adaptées au dimensionnement des structures en mer ArchiMer

The number of Marine Renewable Energy projects has rapidly raised over the last decades. Those require a refined description of environmental conditions, such as sea states, for resource assessments as well as for the conception of the Marine Energy Converters. Engineering studies require long-term data sets so as to assess temporal variability and extreme events of sea states at the scale of the implantation sites.,As a support to its research studies on Marine Renewable Energy, Ifremer is building a specific hindcast database, running the wave model WAVEWATCH III® on an unstructured grid. The wave model extends over the area from the South of the North Sea to the Bay of Biscay with a high spatial resolution and covers a 16 years period from 1996 to 2012....

Étude expérimentale des performances d’une hydrolienne, soumise aux effets de la turbulence et de l’interaction houle-courant ArchiMer
Gaurier, Benoit.
In the context of global warming, the extraction of energy by tidal turbines from marine currents must be integrated into the future energetic mix. Being confronted with a difficult marine environment, it is required to know the turbines’ behaviour when they are submitted to realistic solicitations to guarantee an optimal use. In this work, the marine turbine performance is studied when the machine is submitted to a turbulent current or a combined wave-current effect. The physical representation of trials at reduced scale is first described focusing on the incoming flow characterisation and its effects on a turbine model at 1:20 scale. The location and measurement type of the upstream velocity are discussed to accurately define its performance and its...
