Stiffness and stress efficiency of periodic reinforcing pads for FPSO's hull

Abstract

The hull of FPSO units (Floating Production Storage and Offloading units) suffers from accelerated corrosion. It becomes now mandatory to restore the original thickness of the hull by means of reinforcing pads. For large areas, the pads follow a periodic pattern and are not connected together. Hence, in this work, we apply plate homogenization techniques coupled with finite elements simulations for assessing the behavior of the pads. It is found that, for most geometric configurations studied here, the pads do not provide sufficient strength reinforcement and requires their mechanical connection.
