Análise de instalação e desconexão de riser

An investigation of the dynamic behavior of risers under installation or when suddenly disconnected in the presence of extreme excitations from waves currents and, heave and surge motion is performed. General dynamic responses in terms of displacements, forces, and rotations, for different water depth are obtained considering different boundary and special conditions, to simulate systems operated with more security and efficiency. The extensional natural frequencies for rigid and compliant riser to all water depth and the natural frequencies are also presented. The structural dynamics are observed for the same systems considered like rigid and compliant systems.
