The aims of the present study were to investigate the colonisation of the monopiles, using diver collected video footage and collection of scrape samples, and to compare the results with those of the initial survey, which was completed approximately eight months after installation of the monopiles. The current survey was undertaken two and half years after the initial survey. In addition to the study on the monopiles, seabed sediment samples were required to supplement the post construction grab sampling survey undertaken in March 2007. The diving surveys were undertaken between 23rd September and 26th September 2008 inclusive. A total of four turbines were surveyed (turbines B2, C6, D1 and D5) during the current diving survey.

A comparison is also required with respect to the initial survey, which was completed approximately eight months after the installation of the monopiles. The current survey was undertaken two and half years after the initial survey. In addition to the study of the monopiles, seabed sediment samples were required to supplement the post construction grab sampling survey undertaken in March 2007, as requested by Natural England. Diver collected sediment samples were required, as a 50m safety zone around the turbines was imposed during the grab sampling survey on safety grounds, due to the presence of the inter array cables (Titan, 2007). Diver collected seabed samples were required within the scour pit, where sedimentation had occurred (if appropriate) and upstream and downstream of the scour pit around the turbines.
