DNV GL invites industry partners to start a Joint Industry Project (JIP) for improving the collection and assessment of site conditions data for offshore wind farms. Aiming to increase the efficiency of collecting site conditions, the new JIP will work with stakeholders from across the wind industry. The knowledge generated from the JIP is planned to be ultimately incorporated in a DNV GL recommended practice. The design of an offshore wind farm is dependent on the quality of the calculated site conditions used to derive the design parameters. To achieve an optimal quality in data collection and assessment, extensive and costly investigations are needed at a very early stage of the development, long before final investment decision is made.
