Why is RPD Monitoring Important?

Uneven seabed conditions, soil resistance variations, and other factors can cause unequal forces on the chords during jacking operations. This can lead to a situation where one chord extends or retracts at a slightly different rate compared to the others. While these differences might seem small, even minor variations can accumulate and cause significant stress on the leg structure.

The Role of RPD Systems

Rack Phase Differential Systems are designed to continuously monitor the RPD during jacking operations. These systems typically comprise:

Sensors
Attached to each chord, these sensors measure the position of the rack teeth, providing real-time data on individual chord extension/retraction.

Processing Unit
This unit analyses the sensor data to calculate the RPD value (the absolute sum of the individual chord variations).

Control and Display Unit
This unit provides the operator with a clear visual representation of the RPD for each leg. It can also trigger alarms if the RPD exceeds pre-defined safety limits.

Benefits of Using RPD Systems

Enhanced Safety
By providing real-time monitoring of RPD, these systems enable operators to identify and address potential issues before they escalate into structural problems.

Improved Efficiency
Continuous monitoring eliminates the need for manual measurements, saving time and allowing for faster jacking operations.

Reduced Risk of Downtime
Early detection of RPD issues helps prevent equipment damage and unplanned downtime.
