Abstract
A hydrodynamic cable deployment system suitable for deploying cable from a oil on a moving underwater vessel is disclosed. The present invention provides hydrodynamic assist means for cooperation with a system for the deployment of a cable tether used for communication between a marine vessel and an expendable or non-expendable device launched therefrom by providing means for generating hydrodynamic pressure to produce a current in the direction of cable deployment, assisting in the process of stripping the cable from the coil. The means for generating hydrodynamic pressure can be implemented via a pump, or via a water intake scoop which utilizes the forward movement of the marine vessel to force water therethrough. Additional pressure can be induced and concentrated in a predetermined direction through directional nozzles. Further hydrodynamic assistance can be provided by inserting interspaced diameter constrictions within the inside diameter of a hose through which the cable is deployed, thereby providing periodic increases in the water velocity along the direction of travel of the cable.
