Abstract
A submarine power cable system including: a dynamic submarine power cable having an element with a first axial section and a second axial section which are joined at a joint location; and a bend restriction device arranged around the dynamic submarine power cable, wherein the bend restriction device extends axially over the joint location, and wherein the bend restriction device is arranged to restrict bending of the dynamic submarine power cable at the joint location.
Claims15
A submarine power cable system comprising:
- a dynamic submarine power cable having an element with a first axial section and a second axial section which are joined at a joint location;
- and
- a bend restriction device arranged around the dynamic submarine power cable;
- wherein the bend restriction device extends axially over the joint location, and wherein the bend restriction device is configured to restrict bending of the dynamic submarine power cable at the joint location;
- wherein the element is a metallic water blocking layer;
- and
- wherein the metallic water blocking layer is corrugated along the first axial section and smooth along the second axial section.
