Be notified when your subsea power cable is exposed and at risk of being damaged from external factors.
ABOUT CABLE EXPOSURE
Detect when your power cable is exposed to the open sea.
Cable Exposure is a valuable service for detecting and localizing submarine power cable exposures in offshore wind farms, allowing operators to organize targeted interventions to mitigate the problem. Avoid loss of energy, undersea cable damage, contact and movement. The algorithm utilizes distributed fiber optic temperature measurements and provides actionable insights to drive smart decisions.
“A dynamic seabed environment can have an impact on the seabed covering the power cable and can lead to gradually exposing the cable.”
Cable exposure monitoring allows you to detect the exposed cable.
Cable Exposure uses distributed fiber optic temperature measurements, obtained by using a Distributed Temperature Sensing (DTS) device measuring on one available fiber optic strand in the fiber optic (FO) cable. In today’s submarine power cables FO cables are already embedded.
Our algorithm uses these temperature measurements as one of its input parameters and translates the output into knowledgeable and actionable insights. The service based upon this algorithm visualizes the risk by means of a traffic light system, representing the cable’s position with respect to the seabed surface.
- Red: the cable is exposed and at high risk
- Orange: the cable is at medium risk and near exposure
- Green: the cable is not at risk
The algorithm relies on the fundamental differences between a convectively cooled cable that is exposed and a conductively cooled cable that is buried. Convective heat transfer is much more efficient and therefore temperature differences following power transfer variations are much smaller.
