Abstract
This invention provides a system which includes winding apparatus for haug in and paying out a substantially inextensible steel rope tethering a floating vessel to a moorage or towing vessel, and a control system responsive to signals indicative of the tension in the steel rope and of the length of rope paid out for controlling the winding apparatus. There is also provided an energy reservoir for receiving and storing energy from the winding apparatus when the rope is paid out. The control system operates such that the tension in the steel rope does not exceed a predetermined value.
