Abstract
A dynamic submarine power cable having: a conductor, an insulation system including an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer, a metallic water-blocking layer arranged around the insulation system, and a bedding layer arranged between the outer semiconducting layer and the metallic water-blocking layer, wherein the static friction coefficient between an outer surface of the bedding layer and the metallic water-blocking layer is at least 0.4, and the static friction coefficient between an inner surface of the bedding layer and the outer semiconducting layer is at least 0.4.

A dynamic submarine power cable comprising:
- a conductor,
- an insulation system having an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer,
- a metallic water-blocking layer arranged around the insulation system, and
- a bedding layer arranged between the outer semiconducting layer and the metallic water-blocking layer,
- wherein the static friction coefficient between an outer surface of the bedding layer and the metallic water-blocking layer is at least 0.4, and the static friction coefficient between an inner surface of the bedding layer and the outer semiconducting layer is at least 0.4.
An offshore windfarm system comprising:
- a floating structure;
- and
- a dynamic submarine power cable including:
- a conductor,
- an insulation system having an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer,
- a metallic water-blocking layer arranged around the insulation system, and
- a bedding layer arranged between the outer semiconducting layer and the metallic water-blocking layer, and
- wherein the static friction coefficient between an outer surface of the bedding layer and the metallic water-blocking layer is at least 0.4, and the static friction coefficient between an inner surface of the bedding layer and the outer semiconducting layer is at least 0.4;
- said dynamic submarine power cable connected to the floating structure.
