  • Patent number: 4880257
    Abstract: A pressure compensation multi tubular safety joint for use with tubular sections is disclosed wherein a weak link is included that causes the joint to separate under axial load before permanent damage is done to the tubular sections but which compensates for pressure changes in the tubular sections. The joint includes two members, one of which has means for permitting the separation under conditions where the load is only partially axial. The joint further includes means for pre-stressing the joint to relieve the load on the weak link while the joint is lowered into position and further means for relieving the pre-stress through the flowing fluid in the sections.

  • Patent number: 4772158
    Abstract: A system is disclosed for setting inflatable packers underwater. The packers are used to seal the annulus between an anchor pile driven into the sea bed through a leg of the platform or through a skirt sleeve attached to a leg adjacent the sea bed to allow grout to be pumped into the annulus to connect the pile to the leg or skirt sleeve. The packer is inflated by fluid displaced from a pressure chamber located adjacent the packer by fluid under pressure located adjacent the packer, such as the ambient water.
