摘要：
This paper discusses the dynamics of a hybrid production riser designed for a water depth of 1500 m in the harsh environment west of Shetland where one of the main design drivers is offshore installation time. To minimise installation time, a free standing riser was developed comprising a carrier pipe, top and bottom taper sections and an integral subsurface buoy connected by flexibles to the moored FPSO. The paper discusses the different dynamic characteristics of the structure during tow out, upending, connection and when installed. The simulation methods used, the design drivers, design compromises and parameter sensitivities are also discussed. It is concluded from extensive dynamic analysis and structural design that the proposed design is feasible and the estimated on-site installation time is 2-3 weeks. (C) 1998 Elsevier Science Ltd.
