Abstract:

A free-standing, marine production riser and a method of installing same for use in deep-water areas to conduct fluids between the marine bottom and the surface. The riser system is comprised of a lower rigid section and an upper flexible section. The lower rigid section has a casing extending from a preset base on the marine bottom to a point just below the zone of turbulence which exists near the surface of the water. A variable-buoyant buoy having a curved upper surface and a central passage therethrough is mounted on the upper end of the casing to support the casing in a substantially vertical position when the casing is in position on the preset base. A remotely actuated connector assembly is provided on the lower end of the casing for connecting the casing to the preset base. A plurality of conduits are run through the passage in the buoy and through guide means in the casing and are remotely connected to mating conduits on the base. Each of a plurality of flexible flowlines is connected to a respective conduit at a point within the passage in the buoy.

Abstract:

An apparatus for manufacturing composite parts. An expandable tool with a transfer system may be moved on a surface of the expandable tool into an outer mold line tool with a composite material laid up on the outer mold line tool. The expandable tool may be expanded in the outer mold line tool to change the surface from a retracted state to an expanded state. The transfer system may be transferred from the expandable tool with the surface in the expanded state to the outer mold line tool.
