Abstract
The base of an offshore gravity platform consists of at least two separately formed caissons, preferably of concrete, which are mounted one on top of the other or another. The roof of the lower of adjacent caissons and/or the bottom of the adjacent upper caisson is or are so shaped as to form between the caissons a space which is rendered substantially fluid-tight and wherein, when the platform is floating on the sea and when the platform is standing on the sea bed, fluid pressure in the space between the caissons is such that the two caissons are urged tightly together by hydrostatic pressure. Adjacent caissons may also be mechanically secured together.
