Abstract
1402452 Boring earth etc; offshore structures TEXACO DEVELOPMENT CORP 12 Aug 1972 37724/72 Headings E1F and EIH A marine platform for drilling wells into the ocean floor has a curved leg 16 which is held substantially vertically at its upper end and which is provided with channels for piles 21 and drill strings 42, Fig. 5. The platform may be supported by a plurality of such curved legs 16 together with one or more straight legs 17, Fig. 1. Each curved leg 16 comprises an outer cylindrical casing 18, an inner cylindrical shell 19, and a plurality of pile guides 32, 33 positioned in the annulus therebetween. The pile guides are both longitudinally spaced along the leg and peripherally spaced about the shell 19. Each pile guide is provided with a guide shoe 28, to assist in guiding the piles 21 through the leg. When the piles are positioned in the substrate, they are retained in position by pumping fluidized cement through conduits 36 and 39 into the space 20 between the casing and the shell, a fluid seal in the form of a resilient ring 40 being provided between the pile guide and the pile.
