Seabed-to-desk data harvesting with HydroSurv
Combining uncrewed surface vessels (USVs) and cloud services can help offshore wind farm developers and operators collect and act on ocean data faster and more efficiently. Learn how we’re using our expertise to make rapid seabed-to-desk metocean data collection happen with USV innovator HydroSurv.
The challenge
Offshore renewable energy projects need data throughout their lifespans to support proper design, installation, operation, and maintenance*. This includes bathymetry and geotechnical data, but also metocean data, such as current, wave and sea height characteristics.
Water current profiles, for example, are needed to help locate turbine foundations, cables and cable landfalls. During the life of a project, operators need to understand what’s happening in the water column and at the seabed, to prevent downtime, ensure safe and efficient operations and understand fatigue life.
As wind farms start to be built in deeper waters, ocean data becomes even more critical, as conditions become more complex and especially where floating platforms will be deployed. Water current, height and direction are all critical, for planning and operations.
Traditionally, much of this data is gathered using seabed sensors, such as acoustic Doppler current profilers (ADCPs) and pressure sensors, and conventional crewed vessels. However, when accurate spatial and temporal data is required, this isn’t always efficient. The required frequency of site visits to gain sufficient data increase risk and cost, especially when sites are further from shore. Because of this, there is growing demand for remote, lower cost and emissions survey and data harvesting solutions that help reduce downtime and improve yield.
