Installation of logger on a drilling riser
Features & Benefits
- Display all relevant parameters on one screen
- Display operation limits of the measured parameters
- Raise alarms upon exceedence of limits
- Fatigue damage tracking of riser components
 The DRILLASSURE™ drilling riser monitoring system provides critical information to support day-to-day drilling operations and integrity management. It monitors two key riser operating parameters:
- Upper flex joint angles
- Lower stress joint angles
The system's functionality can be expanded by incorporating 2H standard or 3rd party instrumentation.
System Description
An INTEGRIpod inclinometer is attached above and below the stress joint to measure angles. The data is sent to a data acquisition system via hardwired cables.
A further inclinometer is attached to the bottom of the riser above the lower stress joint to measure angles.
The angle data is sent to the topside data acquisition system via an acoustic receiver or through an existing electrical umbilical system.
The measurement data is displayed and compared with preset thresholds. When measurements exceed a predefined threshold, alarms are raised by the software.
Options
- Collect additional data from 3rd party systems (current, position, wave height, hook load, tensioner stroke, etc)
- Measure riser base tension using an INTEGRIcollar strain sensor.
- Measure motion along the riser using INTEGRIpod motion loggers to detect vortex-induced-vibration (VIV) and estimate fatigue damage
- Track fatigue damage in strategic areas using dynamic curvature sensor INTEGRIstick
