Deepwater Nonlinear Coupled Analysis Tool

摘要

This paper presents a consistent analytical approach for the prediction of nonlinear-coupled effects among platform, moorings/tendons and risers. The approach is based on a newly launched Deepwater Nonlinear Coupled Analysis Tool (DeepCAT) which is jointly developed by ABS and ABB. DeepCAT, comprised of two existing numerical algorithms within COUNAT (a time domain motion simulation code) and CABLE3D (a time domain cable dynamic analysis code), is able to simulate platform motions and the associated mooring/tendon and riser tensions, including second-order effects due to wind, current and waves.
