Numerical intact stability evaluation of submerged floating modular habitats

Abstract

In this study, a numerical model of a submerged floating housing system comprising three vertically connected modular ellipsoidal-shaped habitat hulls of different sizes and six symmetrically running tension-leg mooring ropes is theorized using MATLAB and tested for the habitat complex’s hydrodynamic stability using OrcaFlex. The objectives are to design a practicable underwater habitat complex model and evaluate its intact stability against environmental forcings at the nominee offshore installation location near Dokdo island. The stability characteristics of this model underwater housing system, including sufficient buoyancy and angular behavior of each hull as well as their relative displacements between neighboring hulls under acceleration, are investigated with respect to the habitability within the complex
