How will the turbines be kept in position?
There is a firm footing for turbines in the harbour mouth. Side sonar scans, CCTV video footage, dredge samples and samples taken from the harbour floor in the turbine area by commercial divers suggest the floor is very hard and made up of either bare scoured sandstone, or densely packed large grain sand on a bed of sandstone. The divers used a water pump and lance, sheer vane gauge and hand penetrometer to asses the nature of the harbour floor. The divers also noted that visibility is extremily poor in the channel.
