Abstract: Disclosed is a deep water anchoring system including a structural body floating at the surface of a body of water and with an intermediate floating member directly under and spaced from the floating structural body, the intermediate floating member being submerged below the surface of the water a distance sufficient to be unaffected directly by surface winds and waves. A gravity anchor along the bed of the body of water is coupled to the intermediate floating member via multiple cables which perferably extend angularly outwardly from the intermediate floating member. The anchoring system is provided with at least three separate and rigid rods, each of which are rotatably coupled at one end to the intermediate floating member and rotatably coupled at the other end to the floating structural body.

Abstract: This invention relates to means for protecting nuclear reactors and other structures from earthquakes, explosions, cyclones and other sources of sudden external shock, said means including a support system comprised of a base, a pedestal, hanger-rods and an elastomer element.

Abstract: A structural body such as a nuclear power plant, or the like, can be anchored in an earthquake-resistant manner by supporting the structural body onto a support means so that relative horizontal movement between the body and the support means can take place in all directions. Frictional force generated between the structural body and the support means is less than the force required to move the structural body together with the support means when the latter is subjected to a force having a horizontal component.
