Abstract
For the foundation of large offshore platforms in deep water a suitable type of foundation is a gravity foundation. This is a large and heavy concrete structure, usually consisting of a series of cells, see figure 11.1, with a number of towers on which the actual platform is built. The basic structural principle of this type of foundation is that the large weight of the structure results in large vertical stresses below the foundation, which enable to withstand the large horizontal shear stresses that are generated by the wave loading during storms. The structure may be built onshore, for instance in a dockyard, and then floated to its offshore location, where it is placed by submerging a number of cells. Later the structure is completed by adding the topside facilities.
