Offshore Foundation Cable Protection Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing offshore structure foundation systems with floating foundations face challenges in reliably monitoring the anchoring state, as transmission cables are prone to damage, leading to inaccurate anchoring status detection.
Innovation Solution
The integration of a protection element that guides the transmission cable through sections between the holding element and the anchor or floating body, providing a protective sleeve to safeguard the cable from damage during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission cable is laid between the floating body and the anchor to monitor anchoring state, then the monitoring capability is improved, but the cable is prone to damage from external influences
Solution Approach 1:
A protection element is introduced as an intermediary component between the transmission cable and the external environment. This protection element serves as a mediator that shields the cable from harmful factors such as mechanical damage, corrosion, or abrasion, while still allowing the cable to perform its monitoring function. The protection element acts as a protective barrier without interfering with the cable's ability to transmit signals between the floating body and the anchor.
2Stability of the object's composition
If the transmission cable is fixed together with the holding element on the floating body or anchor, then the connection stability is improved, but the cable becomes more vulnerable to damage during operation
Solution Approach 1:
The connection system is segmented into distinct functional components: the holding element (anchor chain or rope) that provides mechanical connection stability, and the transmission cable that carries monitoring signals. The protection element is introduced as a separate protective segment. This segmentation allows each component to perform its specific function independently - the holding element maintains stable connection while the protected cable transmits signals without being directly exposed to damage risks.
3Ease of operation
If the transmission cable is exposed during operation to allow movement between floating body and anchor, then the mobility is improved, but the cable is exposed to external influences and damage
Solution Approach 1:
The protection element is designed as a flexible protective covering that allows the transmission cable to move and flex during operation while maintaining protection. This flexible shell or thin film structure enables the cable to accommodate the relative movements between the floating body and anchor without compromising the cable's mobility, while simultaneously shielding it from external harmful factors such as mechanical abrasion or environmental damage.

AI summary
Described and disclosed is a foundation structure of an offshore structure, in particular of a wind turbine, with a floating foundation, including at least one floating body for floating on the surface of the sea, at least one anchor for anchoring the at least one floating body the seafloor and at least one holding element for holding the at least one floating body to the at least one anchor. At least one transmission cable extends from the at least one anchor along the at least one holding element to the at least one floating body and/or back. To enable a reliable monitoring of the anchoring of the offshore structure, provision is made for the transmission cable to be guided in sections through at least one protection element provided between the holding element and the at least one anchor and/or the at least one floating body.
