Meaning
Structural health monitoring ensures the continued functionality of composite cables delivering power, chemicals, signals and fiber optics to offshore wells. Subsea umbilical integrity is maintained through a combination of periodic testing and real-time sensor data. This program protects the connection between the surface facility and the subsea production system from environmental and operational damage.
Hydraulic Continuity
Pressure tests confirm that the fluid lines remain leak-free and capable of operating valves. Hydraulic continuity is a primary indicator of subsea umbilical integrity during the installation and commissioning phase.
Insulation Resistance
Electrical checks measure the quality of the cable shielding to prevent short circuits in the power supply. If subsea umbilical integrity is compromised by water ingress, the resulting power loss can shut down an entire field. Specialized software monitors these electrical properties to detect small changes before a total failure occurs.
Fatigue Life
Mechanical stress from wave action and ocean currents is modeled to predict the remaining duration of the asset. Because subsea umbilical integrity is affected by the constant movement of the riser, engineers use strain gauges to track the accumulation of load cycles. A proactive replacement strategy based on this data prevents the high cost of an emergency repair in deep water.
