Abstract

A subsea system I provided for mounting a cable to a pipeline ( 1 ), having a holding means ( 2 ) for holding the cable, where the system further comprises a track ( 3 ) around at least parts of the circumference of the pipeline ( 1 ). The holding means ( 2 ) has a sledge element ( 4 ), and the track ( 3 ) and the sledge element are slidably connected such that the sledge element may move along said track.

First claim

The invention claimed is:

1. A subsea system for mounting a cable to a pipeline comprising:
holding means for holding the cable and a track around at least parts of the circumference of the pipeline,
wherein the holding means includes a sledge element, and
the track and the sledge element are slidably connected such that the sledge element is movable along said track,
wherein the sledge and the track element have cooperating ribs and recesses which hold the sledge in place against the track while allowing it to move along the track element around the pipeline, and
wherein said ribs are placed inside and in contact with said recesses so as to prevent the sledge element to radially deviate from the track.

2. The system according to claim 1 , wherein the connection between the track and the sledge element prevents said sledge element from moving in a radial direction in relation to the pipeline.

3. The system according to claim 2 , wherein the connection comprises at least one recess and at least one cooperating rib.

4. The system according to claim 1 , wherein the holding means comprises a clamp.

5. The system according to claim 4 , wherein at least parts of the clamp is pivotably connected to the sledge element.

6. The system according to claim 1 , wherein the connection between the sledge element and the track comprises means for securing the sledge element at a specific position along said track.

7. The system according to claim 1 , wherein the sledge element is secured to the track by a belt being arrangeable around the pipeline.

8. The system according to claim 1 , wherein the track is an integrated part of the pipeline.

9. The system according to claim 1 , wherein the track is a discrete track element.

10. A method for mounting a cable to a pipeline, comprising the steps of:
arranging a track element around the circumference of the pipeline, or providing a pipeline having a track integrated around the circumference of the pipeline;
fastening the cable to holding means having a sledge element, the sledge and the track elements having cooperating ribs and recesses which hold the sledge in place against the track while allowing it to move along the track element around the pipeline; and
slidably connecting the sledge element to the track element, where said ribs are placed inside and in contact with said recesses so as to prevent the sledge element to radially deviate from the track, such that the sledge element is moveable along said track element.
