Accurasea, Weather And Oceanic Data Measurement Buoy

Accurasea initiated by a collaborative R&D project called BLIDAR, is designed to measure the wind as accurately as possible with a lidar and in all weather and sea conditions that may occur on a wind power site at sea.

ACCURASEA

Blidar project was the winner of FUI’s 11th call to tender. The aim of the project was to create a sea-weather buoy which can precisely quantify the energy resources (particularly the wind power potential using a laser light) available on wind power sites at sea. This R&D project was undertaken in partnership with NKE and the research organisations IFREMER and IRSEEM.

Designed and made in France, Accurasea is a certified project.

Advantages of Accurasea

Can hold any kind of light radar on the market, e.g. the Windcube V2 by Leosphere or the Diabrezza by Mitsubishi Electric.
Adapts its hydrodynamic behaviour to a site or a particular part of the world.
Measures the wind, and also the parameters of the waves and marine current, along with the physical qualities of the marine environment.

The members of the consortium of BLIDAR project

EOLFI

EOLFI is an independent company which specialises in wind power. With offices in France and Taiwan, EOLFI covers the whole value chain of renewable energy: developing offshore floating and onshore projects, managing R&D and Renewable Energy investment funds.

EOLFI was in charge of overseeing the project. We took care of wind analysis and testing both on- and offshore.

nke Instrumentation

NKE Instrumentation designs, creates and sells measurement and surveying instruments for use at sea and in aquatic environments. NKE Instrumentation participates in various R&D programmes both on a national and European level and works in partnership with scientific organisations like IFREMER and the CNRS.

NKE Instrumentation was the lead manager on the project and was responsible for designing and making the complete system. The Accurasea buoy has also taken on board several sensors (multiparameter probe, meteo station, etc.).

IFREMER

Created in 1984, the French Institute for Research and Exploration of the Sea (l'Institut Français pour la Recherche et l'Exploitation de la MER) or IFREMER is a public research institute. IFREMER designs and operates observation, test and surveying tools and manages several scientific databases.

The technology R&D department at the IFREMER centre in Brest has taken an active role in the project. They brought their maritime expertise to the partnership and provide testing resources.

IRSEEM

IRSEEM the Institute for Research of Onboard Electronic Systems (Institut de Recherche en Systèmes Electroniques Embarqués) was founded in 2001 by ESIGELEC School of Graduate Engineering. IRSEEM and their researchers conduct joint research with an applicative purpose. This targets the automobile, aeronautical, renewable energy, telecoms and health sectors.

IRSEEM supervised the acquisition of real-time data during land testing. They were responsible for the development of algorithms to compensate for the movement of the buoy and calculate the parameters of the waves.
