The use of suction piles as in sub sea structure foundations is discussed. The single monopile solution is typically an inverted can of around 7 m in diameter which is lighter than the multiple pile option. After self penetration in soil, an ROV (Remote operated Vessel) is used to apply suction using a pump to displace the trapped water from inside to outside creating a pressure differential and forcing the pile to penetrate into the soil. For suction piles, the undrained average shear strength profile in the top 10 m to 20 m is critical and extensive penetromter, vane and tri-axial testing should be carried out on samples throughout this penetration range.
