|Title:||Diffracted wave field and dynamic forces on offshore structures||Authors:||Sun, Keming||Issue Date:||1993||Citation:||Sun, Keming (1993). Diffracted wave field and dynamic forces on offshore structures. Proceedings of the Third (1993) International Offshore and Polar Engineering Conference : 143-150. ScholarBank@NUS Repository.||Abstract:||A numerical boundary integral approach is proposed for calculating the diffracted wave fields and hydrodynamic forces resulting from the interaction of first order regular waves with a large arbitrary offshore structure. In this paper, the structure is assumed to be a rigid body with arbitrary shapes of cross section and the solution is explored by a special boundary integral method based on the use of a complete and non-singular set of functions. The use of non-singular set of complete functions reduces the integral only over the structural surface, resulting in a considerable saving in computational effort. The numerical solutions of wave diffraction problems due to large offshore structures in ocean waves have been presented to illustrate the accuracy and the range of applicability of proposed method and those are found to be satisfactory.||Source Title:||Proceedings of the Third (1993) International Offshore and Polar Engineering Conference||URI:||http://scholarbank.nus.edu.sg/handle/10635/74135||ISBN:||1880653087|
