Bladed Pump Capstan
Abstract
An apparatus for tensioning a subsurface float line and the like during deployment of the line and thereafter includes a capstan rotatably mounted and located in a liquid medium, the capstan having a bore extending from one end of the capstan to the other end, the bore including a plurality of pump blades for moving the liquid through the bore when the capstan is rotated, the capstan also including turbine blades located around the circumference of the capstan and adjacent both ends of the capstan, the capstan also including a circular surface interposed between the turbine blades for communicating with the line to be tensioned. The pump and turbine blades do work when the capstan is rotated thereby creating a counter rotational (drag) force that tensions the line during and after deployment.
