Abstract: The present disclosure relates to an end fitting and method to install the end fitting to a flexible pipe. The method includes disposing a shell mandrel at a free end of the flexible pipe external to a jacket of the flexible pipe and performing a cutback of layers of the flexible pipe to expose an internal pressure sheath of the flexible pipe. An armor layer of the flexible pipe is radially outward from an axial direction of the flexible pipe. At least one internal pressure containment transition component and at least one internal pressure sheath seal are installed on the exposed free end of the flexible pipe. The end fitting is assembled such that the at least one internal pressure containment transition component and at least one seal are assembled with non-radial fasteners having a backward facing direction.

Abstract: In one aspect, the present disclosure relates to a reinforcement stack of a spoolable pipe composed of a plurality of laminates stacked to form the reinforcement stack. At least one of the plurality of laminates includes an alignment feature configured to align adjacently stacked laminates. In another aspect, the present disclosure relates to a method to manufacture a reinforcement stack of a spoolable pipe. The method includes providing an alignment feature on at least one laminate of a plurality of laminates and arranging the plurality of laminates using the alignment feature to form the reinforcement stack. In another aspect, the present disclosure relates to an armor layer of an unbonded flexible pipe. The armor layer includes a plurality of laminates stacked to form a reinforcement stack of the armor layer in which each laminate of the plurality of laminates comprises an alignment feature to align adjacent laminates.

Abstract: In one aspect, the present disclosure relates to a method to manufacture an armor layer of a spoolable pipe. The method includes forming one or more laminates and wrapping the one or more laminates onto an underlying layer of the pipe. At least one of the laminates is composed of at least one reinforcement tape and at least one fabric tape. The laminates may be bonded to an adjacent laminate, thereby forming a reinforcement stack. In another aspect, the present disclosure relates to a method to manufacture an armor layer of a spoolable pipe. The method includes providing a plurality of reinforcement tapes having fibers oriented in a first direction and disposing at least one fabric tape between at least two layers of the plurality of reinforcement tapes. The fibers of the at least one fabric tape may be oriented in at least a second direction.
