1.1 This recommended practice provides guidelines for the design and operation of subsea completion/workover riser systems run from a floating vessel. It is to serve as a reference for designers and those responsible for the selection of system components. In addition to basic engineering principles, this RP incorporates the accumulated experience of offshore operators, contractors and manufacturers.

1.2 Section 4 describes the primary functions of a completion/workover riser and defines the various types of risers normally used. Each riser component is described in Section 5 with emphasis on design considerations for each component. Section 6 deals with riser analysis and outlines the data requirements and desired analyses results. Section 7 provides a summary of testing and operational considerations. Materials and quality assurance are discussed in Section 8.

1.3 Risers fabricated from special materials such as titanium or fiberglass/composite materials and flexible risers are beyond the scope of this Recommended Practice.

1.4 Workover Control Systems are beyond the scope of this Recommended Practice.
