The ocean towing system plays an important role in the ocean development process. The motion of a towed body is closely coupled with the motion of a towing cable. Munk moment coefficient represents the value of Munk moment which is caused by axial flow. Munk moment seriously affects the motion stability of towed body. In this paper, reference to the parameters of a towed body and by using the lumped mass method, the dynamic simulation of a towed cable-array system in single 360° large-radius ship turn has been established by OrcaFlex. With the change of different Munk coefficients, the effect of real-time response of cable tension and towed body underwater con-figuration have been researched. The results show that Munk moment seriously affects the tension and curvature of the towed cable, especially the section close to the towed body. The larger the Munk moment, the larger the maximum value of the cable tension. This means that the ultimate tension on the cable is also larger. The results provide a theoretical basis for the optimal design of the towed cable and towed body.
