ABSTRACT:
A subsea cable (3) designed to extend from a floating structure (1) on the sea surface down to a subsea structure (2) on the sea floor with a first portion (3a) extending from the floating structure (1) to the sea floor and a second portion (3b) laid in or on the sea floor has an outer sheath and cables and/or conduits inside said outer sheath. The second portion (3b) of the subsea cable (3) is provided with at least one disc-shaped anchor (4) attached to the subsea cable (3b) with clamps. The at least one disc-shaped anchor (4) makes movement of the second portion (3b) more difficult.
