Abstract

Abstract

In order to analyze the riser deformation in complex sea conditions, the energy method and variational principle were adopted to establish the mechanical behavior model, and numerical analysis was made with the central difference quotient. The 3D deformation diagrams of the marine risers were obtained, and the main factors influencing the marine riser deformation were investigated by numerical tests. The results show that the fluid lift force partly affects the riser deformation. The floating drilling platform offset has a significant effect on the riser deformation, i.e. the riser deformation increases dramatically with the offset. The installation of buoyancy blocks improves the stress condition of the marine riser, although that partly increases the riser deformation. Furthermore, the riser deformation decreases along with the top tension and drilling fluid density to some extent.
