Abstract
A submerged multi-purpose facility is optimally located with respect to lateral forces and hydrostatic forces. Lateral force readings are first observed for the geographic location under consideration at a plurality of depths. From these readings, a lateral force curve is developed which is exponential in shape. The mid-range of this curve and just below the mid-range are the depths where the facility is ideally to be located. The facility can then be structured with respect to wall strength to withstand the hydrostatic forces at the depth location determined by the above technique.
Claims7
A method for establishing the location of a Submerged Multi-Purpose Facility beneath the surface of a body of water for affording a support structure capable of withstanding high lateral forces at and near the water surface, which comprises:
- determining at the geographical location where the facility is to be located the magnitude of existing lateral forces at a representive plurality of depth locations,
- plotting said magnitudes and determining a substantially exponential curve wherein the lateral forces at or near the surface define a relatively linear high-force range and the lateral forces near the bottom of the water define a relatively linear low-force range, the generally curvilinear part of the curve between said high-force range and said low-force range defining the knee range of the curve,
- positioning said facility using buoyancy means and ballasting means at a depth location within or below the knee range of the curve, and
- anchoring the facility to the bottom in such a manner so as to permit a small amount of lateral movement by the small lateral forces prevailing at the positioned depth location for the facility.
Submerged Multi-Purpose Facility apparatus positioned beneath the surface of a body of water having a known exponential lateral force curve for depths below its surface, lateral forces at and near the surface defining a relatively linear high-force range and lateral forces near the bottom defining a relatively linear low-force range, there being a defined knee range of the curve therebetween, comprising
- a watertight compartmentalized facility suitable for housing equipment and personnel, said facility being sufficiently buoyant for causing an upward force for locating said facility above said exponential knee range,
- ballasting means attached to said facility for adjustably opposing the upward force for locating the facility at a predetermined depth position at or below the knee range of the curve, and
- slightly flexible bottom anchor means being sufficiently flexible to permit a small amount of lateral movement by the small lateral forces prevailing at the facility depth position without substantial vertical movement.
