Riser monitoring system

Why riser monitoring?

Riser and conductor analysis, when completed before an operation occurs, will use environmental data based on previous trends. This will often include conservatisms due to uncertainties in the planning operations, such as wave data being based on representative conditions, rather than real-time data. This conservatism can sometimes lead to unnecessary downtime for your operation.

Aquaterra Energy’s riser monitoring system has been developed to overcome these challenges. It’s a digital offshore solution that uses wave radars at the surface and accelerometers and aquadopps mounted along the riser system, to provide operators with real time data from their offshore operations via sensors.

Viewable data

This data is retrieved when the riser system is pulled and sent electronically back to shore, where our team of experienced riser analysts interpret the data and refine models to match the exact offshore conditions. This allows for increased operational windows and reduced fatigue for your system.

Accelerations (including power spectral density plots)
Rig and platform displacements (including relative rig to platform)
Fatigue damage accrued

Benefits of the riser monitoring system

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
Monitored data can be used for future riser analysis, improving the analysis models for future operations
Choice of sensors, giving flexibility to client requirements
Provides an engineered process that links the outputs of the riser analysis with the actual environmental conditions offshore, in an auditable and transparent way

Well access for offshore decommissioning: What operators need to consider

Well access needs to be considered early in offshore decommissioning, particularly where ageing infrastructure or legacy equipment can constrain the abandonment programme. Understanding the condition of existing wells helps operators select suitable access systems and offshore units, while our well access engineering and partnership with James Fisher supports coordination from planning through to delivery.
