Riser system for shallow water

摘要

Shallow water and high wave induced ship motions create a challenging and harsh environment for flexible risers and umbilicals. In this article two new riser systems are presented and analysed, by Yves De Leeneer, Prosafe Production Pte Ltd. Results of computer simulations for different load cases are presented and compared with the results of model tests. In shallow water riser systems (risers in this text means flexible unbonded flexible risers, subsea hose risers and umbilicals) are subject to a number of environmental and spatial parameters that increase the difficulty of finding a suitable riser configuration as well as creating high loads on the riser system.
