...Stael F. Senra; Marcos Donato A. S. Ferreira; Allan C. Oliveira; Bernardo D. Sena; Vinicius G. Prado; Celso Pupo Pesce The dynamic behavior of risers is highly influenced by the floating production unit (FPU) motions, associated with environmental loads, caused by waves, current, and wind...

...Dimitrios G. Pavlou Production and deep-sea mining risers should have sufficient flexibility to avoid severe loading due to vessel motions. Free hanging catenary is the simplest and cheapest configuration because of the ease of installation and the minimal requirements for subsea infrastructure...

... are then estimated using a least-square method. A nonlinear oscillator with a quadratic stiffness term is introduced, and the methodology is applied to check the applicability and accuracy. The methodology is applied to a more realistic engineering problem of a simplified riser under irregular wave excitation...
