ABSTRACT:
A composite marine riser may be formed, in one embodiment, of a pair of threaded metallic sections having threaded external surfaces. The threaded external surfaces may taper from a larger to a smaller diameter. The composite material may be formed over the threaded external surfaces, which surfaces serve to transfer force from the metallic sections to the composite material.
