Latest Patents
Changshi Mao holds a patent for a riser keel joint assembly. This invention features a tapered riser joint that connects to a larger diameter outer sleeve through a unique connection. This design allows the tapered section and outer sleeve to function as a single unit. The outer sleeve provides the necessary sliding interface between the riser and the guide at the hull's keel while also offering some bending compliance needed for the transition from the riser supported in the hull to the unsupported riser below. The tapered section contributes the remaining bending compliance required for this transition. The connection between the tapered and sleeve sections is achieved through a forged, machined ring plate welded to the bottom end of the sleeve, which serves as a base for bolted or threaded attachment points for the tapered riser joint below the ring plate and the internal riser joint that extends to the surface. This innovative design has the potential to improve marine operations significantly.
