An improved numerical method is used to simulate the dynamic behavior of a two part towing cable
systems during turnings. In U turns and full turns, periodical heave motions are found both for the towed vehicle
and for the depressor. Periodic motions of the subsea units and of the cable surface tension are closely related to
the turning parameters, such as turning velocity and turning radius. System parameters, such as length of the
second cable and the vehicle hydrodynamics, also damp turning instability.
