Abstract

Provided is a cable hang-off arrangement of an elevated platform including a number of tubular enclosures, wherein a tubular enclosure is configured to accommodate a transmission cable arrangement and includes a vertical section arranged for connection to a supporting structure of the elevated platform; a horizontal section arranged at the level of the elevated platform; and a curved section between the vertical section and the horizontal section. Also provided is a tubular enclosure of such a cable hang-off arrangement; an offshore facility; and a method of securing a transmission cable arrangement to such an offshore facility.

First claim

The claims are as follows:

1. A cable hang-off arrangement of an elevated platform comprising a plurality of tubular enclosures, wherein a tubular enclosure is configured to accommodate a transmission cable arrangement, the cable hang-off arrangement comprising:
a vertical section arranged for connection to a supporting structure of the elevated platform;
a horizontal section arranged at a level of the elevated platform and configured to guide the transmission cable arrangement into the elevated platform; and
a curved section between the vertical section and the horizontal section.

2. The cable hang-off arrangement according to claim 1 , wherein the plurality of tubular enclosures is three tubular enclosures.

3. The cable hang-off arrangement according to claim 1 , comprising a single vertical section configured to accommodate transmission cable arrangements of the plurality of tubular enclosures.

4. The cable hang-off arrangement according to claim 1 , comprising a protective barrel arranged to at least partially enclose the vertical section of the cable hang-off arrangement.

5. The cable hang-off arrangement according to claim 1 , comprising an inverted conical structure at a base of the cable hang-off arrangement.

6. The cable hang-off arrangement according to claim 1 , comprising an end connector configured for mounting to the base of a vertical section of the tubular enclosure.

7. The cable hang-off arrangement according to claim 6 , wherein an end connector is oriented in a direction of a sea cable arrangement.

8. The cable hang-off arrangement according to claim 1 , comprising a mounting means for mounting a horizontal section of the tubular enclosure at the level of the elevated platform.

9. The cable hang-off arrangement of claim 1 , wherein the horizontal section is configured to guide the transmission cable arrangement into the elevated platform through an opening in a side wall of a transition piece of the elevated platform.

10. An offshore facility comprising:
an elevated platform arranged on a supporting structure; and
a cable hang-off arrangement according to claim 1 , configured to accommodate at least one transmission cable arrangement for electrically connecting the offshore facility to at least one further facility.

11. A method of securing a transmission cable arrangement of an offshore facility according to claim 10 using a cable hang-off arrangement, the method comprising:
providing a number of transmission cable arrangements for electrically connecting the offshore facility to at least one further facility; and
arranging each transmission cable arrangement in a tubular enclosure of the cable hang-off arrangement.

12. A tubular enclosure of a cable hang-off arrangement of an elevated platform, the tubular enclosure being configured to accommodate a transmission cable arrangement and the cable hang-off arrangement comprising:
a vertical section arranged for connection to a support of the elevated platform;
a horizontal section arranged at a level of the elevated platform and configured to guide the transmission cable arrangement into the elevated platform; and
a curved section between the vertical section and the horizontal section.

13. The tubular enclosure according to claim 12 , wherein the horizontal section, the vertical section and the curved section have a same diameter.

14. The tubular enclosure according to claim 12 , wherein the tubular enclosure is dimensioned to enclose a plurality of pipes of the transmission cable arrangement.

15. The tubular enclosure according to claim 12 , wherein the curved section subtends an arc of at least 90° between the vertical section and the horizontal section.
