Project description

The RAVE research initiative is concerned with accompanying scientific research in the alpha ventus offshore test field, which has been in operation since 2010. The focus is on recording parameters relevant to construction, operation and the environment. The BSH is in charge of the coordination of the measurement service, carries out the oceanographic measurements and operates the RAVE research archive; the subcontractors DNVGL and UL International carry out the plant-specific measurements. BSH has started to extend the oceanographic measurements to other cooperating offshore wind farms in order to establish a large-scale sea state monitoring network together with the other BSH operated sea state measurement stations and to provide quality-controlled sea state data. The OpenRAVE collaborative project will continue existing measurements and ongoing coordination. The collaborative partner Fraunhofer IWES is responsible for the coordination and public relations of the RAVE research initiative. The collaborative partner LUH analyzes the environmentally relevant data to investigate the location dependence of the wind-wave correlation and to compare the theoretical approaches of wave-current interaction with field data for the first time.

Objectives

The fundamental objective of OpenRAVE is to continue the globally unique and valuable data set acquired at alpha ventus and to enable research projects to access this data. The uniform and automated quality control of the measurement data will be continued and further developed. In-situ sea state data from German measuring stations will continue to be bundled and made available in a uniform way on the sea state portal. For this purpose, four additional sea state measuring stations will be established in German offshore wind farms and the data of the sea state stations of the federal state authorities as well as research institutions will be acquired. In addition, highly specialized sea state data products are created for the offshore wind industry and research.
