Paper Number: OTC-31259-MS
... on the operating condition during the life of field including fluid contents and top tension. One solution to reduce this uncertainty is to deploy a fatigue monitoring system to assure the long-term integrity and performance of these riser systems. This paper presents results from a recent TTR monitoring campaign...

... of the riser systems and explore the possibility of life extension in a structured and systematic way. A Deep Draft Caisson Vessel (DDCV), has been keeping up its class services for the past 17 years since it was installed in 2000. It was expected to extend the riser design life by 10 more years. This paper...

... Abstract In case of conventional shallow-draft semisubmersibles, unacceptably large riser stroke was the restricting factor for dry-tree-riser-system development. Many developments to address this issue have focused on using larger draft and size with extra heave-damping plates, which results...

... on every floating platform and on every riser system attached to the vessel. This is due to the high perceived capital or operational costs of direct subsea monitoring when deployed on every riser to reliably monitor over the entire service life. Furthermore, monitoring devices are typically installed...

Abstract Fatigue damage to mooring lines and riser system components due to current driven Vortex Induced Motions (VIM) governs the design of deepwater floating platforms, especially in the Gulf of Mexico (GoM). Fatigue estimations based on scaled model testing were traditionally used for VIM...
