Anchor rope system for fixing an offshore device to a subsea floor, comprising:
- at least one anchor rope surrounded by at least one sheathing, and
- at least one condition sensor formed by at least one fiber optic cable,
- wherein the at least one fiber optic cable comprises at least one optical fiber,
- wherein the at least one optical fiber is arranged in a tubular element of the fiber optic cable,
- wherein the fiber optic cable comprises an armoring layer surrounding the tubular element,
- wherein the armoring layer comprises a plurality of armoring ropes formed from fiber composite material and/or metal.
Anchor rope monitoring system for monitoring the condition of an anchor rope system that fixes an offshore device to a subsea floor, comprising at least one anchor rope surrounded by at least one sheathing, and at least one condition sensor formed by at least one fiber optic cable, the anchor rope monitoring system comprising:
- at least one monitoring device connectable to the at least one fiber optic cable of the anchor rope system to be monitored,
- wherein the monitoring device comprises an evaluation unit configured to evaluate at least one sensor signal receivable by the fiber optic cable,
- wherein the evaluation unit is configured to compare the received sensor signal with at least one reference criterion,
- wherein the reference criterion is based on at least one historical sensor signal of the anchor rope system to be monitored,
- wherein a plurality of sensor signals are recorded for each anchor cable system after installation and the at least one reference criterion is determined based on these sensor signals,
- wherein the reference criterion is stored in a data memory of the anchor cable monitoring system.
