The immediately previous report regarding risers and pipelines is ISSC2000 Specialist Committee V.5 Structural Design of Pipeline, Riser and Subsea Systems. It represented the sequel to the report of Committee V.7 Structural Design of Pipeline Systems of the 1997 1SSC. The mandate of ISSC2000 report is as follows. "Concern for the development of appropriate principles for life cycle―design of offshore pipeline, riser and subsea systems designed for the conveyance of fluids, including load and dynamic response. Consideration shall be given to inspection and monitoring procedures, and to the influence of operational decisions on safety." Both reports dealt with the issues related to the structural design of pipeline, riser and subsea systems designed for the conveyance of fluids. There were two main factors driving pipeline and riser technologies during the preparation of ISSC2000 report. The first was the requirement of longer but reliable cost-reduced pipelines connecting wells and the production facilities. The second factor was the inexorable increase in water depths between 1700m and 2800m associated with the exploitation of offshore oil and gas. The contents of the report consist of load and load effect, capacity, installation, design criteria and inspection, repair and maintenance. The topics and brief outputs of the report are summarized below: Relatively matured subsea pipeline and riser technology with further work required for reeled steel catenary risers, deep-water flexible pipes, steel tube umbilicals, composite tubes and large bore coiled tubing for pipeline applications. Importance of accurate prediction of hydrodynamic loads with the aid of rapidly advancing Computational Fluid Dynamics (CFD). Attractive steel catenary risers for deep water applications with additional research for the in-service fatigue life of the welded joints. Maturity of global riser analysis except pipe-sea bed interaction. Necessity of challenge to Voltex Induced Vibration (VIV) especially at high Reynolds numbers and in deep water applications.
