CETO Wave Energy Project with Subcon involvement
Subcon provided foundation grouting. The foundation for the system comprises 3 x 30Te (14m long, 1.8m diameter, 40mm thick) ballasted piles being drilled and grouted into the calcareous seabed.
A system of pipework was fitted to piles prior to installation enabling direct connection of grout supply hoses and consistent delivery of grout throughout the pile annulus. Shear keys were also fitted to piles at the advice of Subcon despite not initially being included in the design.
Following drilling, calcareous bedrock was found to have a lower than predicted capacity making the shear keys an invaluable addition.
