Optimization of slope angles of a barge-shaped FPSO from the towing stability and load perspective

In this study, a parametric investigation is performed using CFD for towing stability and loads according to the forward and aft slope angles of a barge-shaped FPSO. The forward slope angle is considered in a range of 30–60° and the aft slope is examined in a range of 20–50°. As a result of a compar...
