    摘要: A method for governing the elevation, attitude and structural integrity of a pressure-containing vessel in a body of liquid counterbalances flotation and incompressible ballast mediums against each other in separate serial compartments. Varying the quantity of incompressible ballast medium allows control of the elevation and attitude of the vessel. If the flotation medium is compressible, varying the quantity of flotation medium allows control of the ambient pressure of the vessel. The method facilitates floating and towing and laying of an undersea pipeline on, to and at a deep water site.

    摘要: A clamping arrangement 10 of a buoyancy clamp assembly. The arrangement 10 includes three identical arcuate members 12 engageable together to define a ring. Each of the arcuate members 12 has three discrete resilient members 14 engageable on for instance a pipe 68. Engagement members 42 are provided extendable between adjacent pair of arcuate members 12 to prevent relative twisting of adjacent arcuate members 12.
