MARINE FOUNDATIONS COMPRISING SUCTION PILES
A marine foundation such as a jacket or a tripod foundation for a wind turbine comprises suction piles 18 that are subjected, in service, to cyclical loading of compression phases and tension phases in alternation. Each pile 18 has a one-way valve 34 that opens and closes autonomously in response to pressure differentials between the internal chamber 28 and the surrounding water. The valve 34 opens autonomously during the compression phases due to an overpressure within the pile 18 and to effect fluid communication between an internal chamber 28 of the pile 18 and surrounding water. Water is thereby ejected from within the chamber 28 through the valve 34. During the tension phases, the valve 34 closes automatically due to underpressure and water is admitted into the pile 18 only through soil 24 within a skirt 26 of the pile 18. Thus, a unidirectional, generally upward flow of water 52 is driven through the soil 24 within the skirt 26 during the compression and tension phases, maximising water flow friction and reducing the risk of liquefaction of the soil.
