Abstract

The three-dimensional singularity distribution or boundary integral method has been demonstrated by many investigators to be the most versatile and reliable technique for the calculation of harmonic oscillation of a truly three-dimensional floating marine structure in potential flow field. -- In the present work, a numerical scheme is presented and a computer program has been developed based on the three-dimensional singularity distribution theory. The program calculates the first order wave exciting forces and moments, hydrodynamic co-efficients and motion responses in six degrees of freedom of any floating marine structure of arbitrary geometry for different angles of heading. Calculations are performed for a floating rectangular box, a vertical circular cylinder and a 130,000 ton dwt tanker. The results are compared with available published results based on the same theoretical model. In general, a good agreement is found between the results. -- To demonstrate the versatility and effectiveness of the program, calculations are also performed for a semi-submersible and the results are presented.
