Designation of the Boundary Conditions for Estimating the Thrust Loss due to Thruster-Hull Interactions

The azimuth thruster is mainly installed on a vessel that requires dynamic positioning (DP) function for special purposes. When the operates DP, thrust loss induced by thruster-hull interaction. This study examined influence of boundary conditions in numerical simulations predicting loss. Wind turbine installation vessels (WTIV) and floating production storage offloading (FPSO) were chosen as target vessels. In this study, two types boundaries defined. first consideration condition was assigned with angle thruster, whereas it fixed regardless thruster. predicted according to these showed difference. observation originated from current load vessel. Therefore, which not need be designated obtain realistic simulation.
