A guide system for securing a torpedo pre-set power cable to move within a torpedo tube is provided. The guide system includes a longitudinal keeper and a guide assembly. The longitudinal keeper secures the power cable and includes a protrusion. A channel of the guide assembly connects to a Torpedo Mount Dispenser such that the channel receives the protrusion with the keeper sliding within and along a length of the channel. An alternate channel connects to a torpedo tube land and is configured to pivot to a stowed position and a deployed position where the channel is configured to receive the protrusion of the keeper such that the keeper slides within and along a length of the channel. When using each of the channels, the power cable can move within the torpedo tube when the protrusion of the keeper with the secured power cable slides within each channel.

A suspension system receives an associated cable. The suspension system includes first and second mount arms disposed in spaced relation that receive a collar assembly having first and second collar members dimensioned to circumferentially enclose around the associated cable in a first assembled position, and a second open position, where the first and second collar members do not circumferentially enclose the associated cable. Sheave mount assemblies are provided along the interconnecting posts and various degrees of freedom are incorporated into the modular assembly.

The present disclosure relates to a method for festooning a power cable while deploying it in a deployment site comprising a rail having a start and an end, the method comprising the steps of: providing the cable with a plurality of cable holders slidably movable along the rail, each two consecutive holders being spaced at a holder predetermined distance on the cable; providing a festooning apparatus after the start of the rail, the festooning apparatus comprising a lowering device movable between a raised position and a lowered position; deploying the cable along the rail by repeating the following sub-steps: engaging on the rail one holder after the other and moving them thereon; when one holder oversteps the festooning apparatus, operating the festooning apparatus to move the lowering device from the raised position towards the lowered position, thus engaging the cable at a point between two consecutive holders; when the lowering device reaches the lowered position, obtaining a sagged portion of cable and a shortening of the holder predetermined distance; operating the festooning apparatus to move the lowering device from the lowered position towards the raised position, thus disengaging it from the cable; fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged cable portion; and advancing the sagged cable portion along the rail.
