Abstract
ABSTRACTCylindrical structures are widely used in offshore engineering, such as the hard tank of a spar platform, columns of a semi-submersible, jackets, drilling pipes, risers and so on. Interactions between the waves and offshore structures are of great importance for engineering applications. This paper focuses on the inline wave force acting on a truncated vertical circular cylinder. Experimental studies are carried out in the wave tank at Shanghai Jiao Tong University in China. The diameter of the cylinder (D) is 10 cm and five submergence depths (hs), i.e., hs= 0.5D, 1D, 2D, 3D, 4D, are considered, respectively. The inline force is found to be influenced by the submerged depth of the cylinder, wave steepness and scatter parameter. High-harmonic wave forces and the second-load cycle are also discussed in the paper.
