Keywords: Riser, seabed, fatigue, random waves, soil stiffness Developer Documentation The developer guide is targeted towards users wishing to extend the functionality provided within Open-FAST. Also included are instructions for using the automated test suite, which serves as a suite of examples. The results indicated that the SCR responses were highly separated in terms of fatigue performance especially for weak to normal soils. of the OpenFAST and its underlying modules, as well as theory and verication documentation. Model (IV) which represents a very stiff seabed, had a minimum fatigue life of about 6.5 percent of the model (I). This paper presents a curved floating bridges dynamic behaviors under the wind, wave, and current loads. Model (I), which represents weak soils with very low stiffness, could resist on continuously applied harsh environmental condition for 139.6 days. A floating bridge is an innovative solution for deep-water and long-distance crossing. Results show that the seabed stiffness makes considerable differences in dynamic and fatigue responses of SCRs in the touch down zone (TDZ) and reveal the importance of proper seabed stiffness modeling. Also, the effect of seabed stiffness on the structural behavior of the SCR is studied.
So in this study, the significance of SCR-seabed interaction is investigated. It is needed to have more understandings of SCR behavior. Steel Catenary Riser (SCR) connected to Floating, Production, Storage, and Offloading unit (FP SO), is a preferred and commonly used solution to the challenges. Offshore platforms and marine risers, as the main parts of this industry, have many challenges and design issues.
