Cable armour stripping unit

1. A cable armour stripping unit comprising:

a frame configured to accommodate a transmission cable having a plurality of armoured outer layers arranged about an inner jacket enclosing a plurality of conductors and to hold a cutter arrangement comprising at least one cutting tool arranged to cut into an armoured outer layer of the plurality of armoured outer layers of the transmission cable;

a vertical feed arrangement connected to the frame, the vertical feed arrangement configured to engage the transmission cable to vertically move the transmission cable with respect to the frame; and

wherein the at least one cutting tool is controlled to cut into the armoured outer layer.

2. The cable armour stripping unit according to claim 1 , comprising a control unit for controlling a jointed bracket attaching the at least one cutting tool to the frame position the at least one cutting tool at a pitch angle relative to the transmission cable and/or to position the at least one cutting tool at a roll angle relative to the transmission cable.

3. The cable armour stripping unit according to claim 2 , wherein a cutting tool pitch angle corresponds to a pitch angle of the armoured outer layer.

4. The cable armour stripping unit according to claim 1 , wherein the at least one cutting tool comprises a circular cold saw.

5. The cable armour stripping unit according to claim 1 , comprising a pry tool configured to pry a cut armour layer from the transmission cable.

6. The cable armour stripping unit according to claim 1 , comprising a collector unit configured to collect pieces of cut armour.

7. The cable armour stripping unit according to claim 1 , wherein the vertical feed arrangement and/or a pry tool and/or a collector unit are mounted on the frame.

8. The cable armour stripping unit according to claim 1 , wherein the frame is attached to a transition piece located between an offshore support structure and a wind turbine mounted on the offshore support structure.

9. A method of stripping armour from a transmission cable having a plurality of armoured outer layers arranged about an inner jacket enclosing a plurality of conductors, the method comprising:

arranging the transmission cable within the frame of the cable armour stripping unit according to claim 1 ;

actuating a plurality of cutting tools to cut into an armoured outer layer of the plurality of armoured outer layers of the transmission cable;

actuating the vertical feed arrangement to vertically move the transmission cable with respect to the frame; and

controlling a jointed bracket attaching the least one cutting tool of the plurality of cutting tools to the frame to tilt a rotation axis of the at least one cutting tool relative to the transmission cable.

10. The method according to claim 9 , wherein the actuating the vertical feed arrangement is performed during cutting of an armoured outer layer.

11. The method according to claim 9 , comprising a step of simultaneously controlling a first cutting tool of the plurality of cutting tools to cut a first armoured outer layer of the plurality of armoured outer layers and controlling a second cutting tool of the plurality of cutting tools to cut a second armoured outer layer of the plurality of armoured outer layers.

12. The method according to claim 9 , wherein the plurality of cutting tools are controlled to cut the armoured outer layer in a plurality of pieces.

13. The method according to claim 9 , comprising a step of collecting the plurality of pieces of the cut armoured outer layer.
