Over recent years, the offshore industry has substantially broadened the duties required from different ship hull forms for marine transportation and oil production. They have required the vessels to carry reasonably large deck payload (as ship shape hull form) and low wave induced motions (as semisubmersibles). Therefore, an unusual floating vessel design, which can be regarded as hybrid of monohull and semisubmersible hull shapes can offer a combination advantages of the low wave induced motions and high payload in terms of both these hull forms.
In this research, we first present a survey of twenty eight (28) vessels whose particular dimensions, payloads and displacements are used to define non-dimensional ratios for each vessel with the ratios plotted against each other to reveal some interesting generic variations. Secondly, a simplified hydrodynamic analysis is derived for wave induced heave forces and motions for the typical semisubmersible, tandem and monohull vessels to illustrate their hydrodynamic behavior. The simplified analysis is complemented by a more representative and complicated diffraction theory (Boundary Element Method) based on hydrodynamic analysis of the hull form to yield wave induced motions and inter-hull forces. The material presented in this report offers the possibility of optimizing a vessel，s payload and motions performance at the early stage of preliminary design by selecting some principal particulars.
