Dynamic Responses of Pontoons Connecting Process of Mobile Offshore Base

The dynamic responses of two pontoons while connected with each other in irregular waves are calculated by means of three-dimensional (3-0) potential flow theory. The computation is to find the optimal status for connection at a certain sea state. On the basis of the relative motion of two pontoons in irregular waves, Visual FORTRAN programming language, as well as OpenGL (Open Graphics Library), is used to develop a set of virtual reality system of the relative motion of two pontoons, which is fully interactive with realistic effect. The transfinite interpolation scheme is applied for the mesh generation of wave surface, and the wave motion is simulated by surface elevation and calculated by 3-D potential flow theory.
