In global, the NEPTUNE project develops equipment and tools to plan and operate better and overall to reduce costs in offshore wind farms, especially in the Mediterranean Sea. The outcomes of the project are for offshore without depth limitation, for deep-and shallow water; so the market is extremely huge.
One aim of this project is to develop such a floating wind, wave and current measurement system which allows with highly reduced costs compared with bottom mounted masts, to evaluate precisely the wind resources and the site conditions which are needed to adapt and proof the turbine and substructure design. The principal options for such a system to measure the wind speed in different heights are a floating met-mast ora floating LIDAR buoy.
The Mediterranean Sea could be categorized as "complex" sea. Apart from the deepwater situation, there exist very few wind models which can predict well the wind resources up to blade tip height of the wind turbines. The data from the test measurement campaign of a floating prototype will be used to validate and optimize a software tool for wind, wave and current forecast. A one-year-measurement-campaign will be carried out to test the prototype but also to collect enough data for the validation of the forecast tools. The test area is the zone of the future Mediterranean deepwater offshore test wind farm Zèfir.
