Abstract:
1. A disconnect and support mechanism for single segment continuous flexible risers and umbilicals between a subsea wellhead and production manifold above the water line on a floating offshore structure, comprising: a. a rigid buoyant main body portion not in contact with the seabed during use; b. a plurality of projections that are rigidly attached to and extend radially outward from said main body portion; c. a convex section extending substantially from the center of said main body portion, said main body portion and convex section having conduits for receiving the risers and umbilicals therethrough and providing support after disconnecting the single segment continuous flexible risers and umbilicals; and d. a plurality of arch-shaped riser and umbilical supports on each of said projections, said supports being shaped and sized such that the risers and umbilicals are not over stressed from bending during installation or operation and the supported risers and umbilicals do not contact the sea floor when disconnected from the floating offshore structure.
