After the initial five years of measurements, a key driver for the continuation of the work was the validation of the engineering designs of the turbine towers and monopile foundations under the in-situ wave environment. This study specifically collected wave time series data over a seven-year period (November 2009 to January 2017) using a Datawell MkIII Directional Waverider (DWR) buoy sited ca. 8 NM from shore within the area of the WoDS windfarm. After undergoing automated QA procedures, the near-real time telemetry data were then made available to SPR and DONG Energy via a private FTP site. The full dataset provides DONG Energy and SPR with a better understanding of the inter-annual variability of the wave climate within the WoDS windfarm.

In addition, the preparation, servicing and deployment of the equipment in accordance with manufacturer’s recommendations ensured that data downloaded from the instruments were of the highest standard. Therefore, any data identified as unreliable were due to reasons beyond Cefas’ control (e.g., spectrally derived directional parameters from a Waverider are unreliable at low wave heights – see below). Post‐recovery Waverider data undergoes a series of processing steps followed by automated and manual quality assurance (QA) processes. The 30‐minute full spectrum (SPT) files were first renamed to include the deployment name and uploaded to the Cefas SmartBuoy/WaveNet SQL2013 database using bespoke software that conducts automated QA on the wave parameters during the process. https://www.marinedataexchange.co.uk/details/2307/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
