Platform & Rig Monitoring

When drilling a well over a platform from a jack-up rig, environmental motion will mean that the rig is moving relative to the platform. Your pre-project riser analysis report will have provided the maximum allowable relative offset for the riser system, but there is no way of knowing whether the motion is within allowable bands. Plus, there is no way or correlating this motion with the environmental data for your exact offshore conditions.

Aquaterra Energy’s Platform and Rig Monitoring system has been developed to overcome these exact challenges – it’s a modular, real-time digital solution which incorporates accelerometers and operational sensors. When combined in our system they provide operators with real-time wave, motion and current data for the platform, rig and riser system.

Real-time data provided:

• Wave height and period
• Current profile with depth
• Accelerations (including power spectral density plots)
• Rig and platform displacements (including relative rig to platform)
• Fatigue damage accrued

Our Platform and Rig Digital Monitoring System records offshore via sensors and sends this data back to onshore operations. The delivery of the real-time wave, motion and current data for your operation allows for increased operational windows, reduced fatigue and improved overall project efficiency.

Benefits and advantages:

• Removes conservatisms that are embedded in traditional riser and conductor analysis approaches, leading to better decision making offshore and increased operational uptime
• With the right system, operators can make informed decisions on using up-to-date and more representative data
• Choice of sensors, giving flexibility to client requirements
• Data is viewable both offshore and onshore, allowing for critical decision making with up-to-date data
• Fatigue monitoring is based on the actual environmental conditions, rather than estimates in traditional riser analysis. This improves the fatigue predictions and removes conservatisms
