Title: Seabed flexible connection between tower and foundation - permits access down tower into foundation inside bearing ring
Inventor: RASCH CHRISTFRIED DR ING
IPC: B63B35/44
Filed: 1975-04-29
Abstract: An elastic, accessible hinge for anchoring under-sea structures comprises a laminated rubber, neoprene or similar joint consisting of two rigid metal or other plates with the flexible material sandwiched between them. One plate presents a convex surface to the neoprene the other presents a concave surface. The entire bearing lies on a spherical surface having a centre of rotation outside the bearing in such a way that when the anchored structure rotates (through a limited angle) the movement is predominantly accepted by shear movement in the sandwich bearing and not by normal forces. Pref. the hearing follows an annular course around the imaginary spherical surface so that central access through the bearing to the foundation is possible. This permits, for example, anchor bars for holding the tower of vertical leg down to the foundation. Used in partic. for anchoring underwater towers and other marine structures, where a single foot is held down on a very heavy foundation on the seabed and a certain amt of angular movement must be possible. The arrangement indicated makes this possible while at the same time providing direct access down the centre of the tower to the foundation.
