A subsea shuttle tanker (SST) is a pioneering underwater submarine specifically designed to economically transport CO2 smaller hydrocarbon fields. During loading and unloading of the CO2, SST hovers over well experiences extreme heave motions resulting in hydrostatic loading. Sustaining indispensable as it forms dominating load driving factor determining hull's collapse design. Furthermore, SST's surge motion regulates length flowline evade snap loads. This paper focuses on problem these positional responses at one location when aft thruster fails during offloading using data with shorter time record from another SST. scenario could be practical engineering importance either sensors malfunctioning or similar vessel being for same environmental condition. 2D planar Simulink model used generate empirical required study.
