Hydrodynamic Behaviour of Floating Polygonal Platforms under Wave Action

The hydrodynamic behaviour of floating regular polygonal platforms under wave action was studied by conducting parametric studies. Considering triangular, square, hexagonal, and circular similar size draft, the results show that their added mass, radiation damping, RAOs are similar. However, exciting forces slightly different, particularly horizontal forces. oriented with one its corners in line prevailing direction can lead to a reduction force on platform, feature helps reducing cost mooring system. Moreover, such able disperse waves better multiple directions hence will not pose problems for ships or marine vessels passing platform weather side. Thus, orientation is an important design consideration. From comparison study among different platforms, attenuation performances analyses performed herein studies were sped up considerably using significantly lesser number Fourier coefficient sets series functions define velocity potentials when compared those used previous researchers analytical approaches. adoption radius function defined cosine-type radial perturbation does only generate geometric boundaries but it also simplifies formulation quickens computations.
