Sennen to deliver more accurate predictions of weather windows

27th April 2021

With the next generation of wind farms being built further and further offshore, route planning and forecasts for critical O&M weather windows are crucial, requiring extremely accurate predictions of the weather windows available for each operation. 

Sennen has announced the latest update to its real time weather and weather forecasts module that will enable even more accurate weather predictions, such as the chance of lightning and fog, for London Array.  

The update has been driven by Sennen’s integration with DHI, an international water software development and engineering consultancy firm, together with  StormGeo, the renewable energy industry’s respected leader in weather intelligence. 

Sennen has now integrated StormGeo’s wind models, lightning risk data and forecaster adjusted data four times a day, for London Array’s primary forecast sites. DHI use the same data, running through their models to produce detailed per location forecasts. This leads to the delivery of high-quality data via a consistent and robust API service that is fully integrated with Sennen. All available signals in the API have been integrated into the Sennen platform (e.g., wave height/direction, water depth, current speed/direction, fog risk). 

Nick Elderfield, Managing Director at DHI UK said 

“Navigating offshore wind operations and maintenance make great demands on weather, waves and currents – and therefore on the weather forecasts. Offshore wind farm accessibility and costs of offshore activities are heavily driven by the expected number of operational hours offshore and waiting times for weather windows, suitable for offshore operations. Our partnership with StormGeo and integration with Sennen will provide more reliable weather window estimates.” 

Paul Grimshaw, Sennen Chief Technology Officer and co-founder said: 

“Having more reliable weather forecasts will result in better wind farm accessibility predictions for our clients. O&M becomes more efficient and more cost-effective through reduced project interruptions and downtime, and advanced reporting and analysis.” 

The integration with DHI is the latest update to Sennen’s real time weather and weather forecasts module where clients: 

– Have access to live met-ocean conditions visualised in different formats with customisable dashboards 

– Compare forecast and actual data to boost data accuracy and user confidence

– Can automate prediction of safe working windows based on met-ocean forecasts, individual vessel characteristics and customisable safety considerations (i.e., on wind speed for nacelle work or current speed for diving operations)
