Integrated mooring Riser Design: Analysis Methodology

摘要

The integrated design of deepwater risers and moorintgshas the ptential to bring substantial benefits in the terms of overall system response, cost and safety to a offshore development. Existing design methods, with their origin in shallower water design, have typically not considered design integration. The associated design assumptions need to be reassessed in deeper water, where substantial benefits can accrue from integrated design. The justification for integrated design methods lies in the importance of hydrodynamic loads, stiffness, damping, added mass and potential compliant effects of risers as part of a moored system and also in the need to recognise the precise station keeping requirements of riser systems.
