US 12,126,150 B2 · Method for festooning a power cable

Abstract

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.

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:

providing the power cable with cable holders slidably movable along the rail, each two consecutive of the cable holders being spaced at a holder predetermined distance on the power 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 power cable along the rail by repeating a plurality of sub-steps, the plurality of sub-steps comprising:
engaging, on the rail, one cable holder after the other and moving them thereon;
after one of the cable holders oversteps the festooning apparatus, operating the festooning apparatus to move the lowering device from the raised position towards the lowered position to engage the power cable at a point between two consecutive holders;
after the lowering device reaches the lowered position, obtaining a sagged portion of the power 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 power cable;
fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged portion of the power cable;
and
advancing the sagged portion of the power cable along the rail.

engaging, on the rail, one cable holder of the cable holders after the other and moving them thereon;
after one of the cable holders oversteps a festooning apparatus, moving a lowering device from a raised position towards a lowered position so as to engage the power cable at a point between two consecutive cable holders, each two consecutive cable holders being spaced at a holder predetermined distance on the power cable;
after the lowering device reaches the lowered position, obtaining a sagged portion of the power cable and shortening the holder predetermined distance;
moving the lowering device from the lowered position towards the raised position so as to disengage the power cable;
fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged portion of the power cable;
and
advancing the sagged portion of the power cable along the rail.
