London Array Wind Farm Wind Monitoring Instrumentation

Client - E.ON

Overview

The London Array project in the outer Thames Estuary is currently the world’s largest consented offshore wind farm. At 1, 000MW, the wind farm could eventually power up to 750,000 homes. Dulas has been involved with the London Array project installing wind monitoring instruments and maintaining the met mast since 2008. Dulas regularly visit the mast to replace instrumentation, inspect the tower and more recently, to install a tide level sensor. The London Array met mast is approximately 5 miles out to sea adjacent to one of the largest on-going construction projects in the UK, installing 175 wind turbines.

Implementation

The installation of the new calibrated instruments requires two people to climb up to each instrument, the highest being 80m from sea level.

The data from the instruments is then recorded in the CR 3000 data logger on the platform of the mast and data is then downloaded remotely via GSM modem. In addition to this, some data is sent every ten minutes via satellite communications to the site operations team. The data is used both by the construction team for checking current wind speeds and by the Project Owners data analysts.
