COLLAPSE RESISTANT COMPOSITE RISER

摘要

A composite collapse riser especially useful for deep water mineral, oil and gas exploration and production. The riser has a core with a metal liner (34) and metal composite interfaces (18, 20) at each end. A reinforcing layer (38) of dry fiber laminate, composite material or combination thereof is placed over the metal liner (34). Over the reinforcing layer is a shear ply layer (40), and over the shear ply layer is an outer main layer of composite material (42).
