Analysis of Marine Risers Subjected to Shoal/Deep Water in the Installation Process
Polish Maritime Research, 2022 The dynamics of the installation process of marine risers subjected to shoal/deep seawater is studied. The riser is assumed to be a cantilevered Euler‒Bernoulli beam. The upper end of the riser is clamped on the vessel or the drilling platform. The lower
