Well Integrity Manager
Our structural well integrity services span from design analysis (modelling, simulation and capacity assessment) to structural monitoring with subsequent post-processing of measured data. The services are connected to risers, Xmas trees, wellheads, conductors and casings (down to ~30m below mudline).
Design, verification and re-assessmentDrilling and production systems are often built up of standard components from various suppliers. During the whole system design phase or as a final verification, global nonlinear simulation models are created in order to analyse the system response and to assess the individual components structural capacity.
Re-assessment of system may be required if operational conditions, parameters and/or properties applied in the design phase are changed when the system is installed and put into production.
The deliveries from the work includes structural capacity utilisation for the individual components as well as optionally recommendations for structural improvements (improved structural robustness/reduced utilisation).
Structural monitoringMonitoring systems are made up from a set of sensors, typically accelerometers, inclinometers, strain gauges and displacement sensors, with wired or wireless communication to a computer on the rig for storage, control, processing and visualisation.
Monitoring equipment is applied in cases where:
- The design capacities are limited
- The system or component response is difficult to predict by simulations
- The measurements are, directly or indirectly, used to set operational parameters
- There is a need to monitor fatigue damage due to limited service life
Data and information may also be made available onshore or at other locations on the vessel, and it is essential that sampling of all sensors at sufficient frequencies to reproduce the loads is synchronous.
The monitored responses are either delivered to the client as-is (filtered and quality assured) or they are post-processed where derived quantities are supplied to the client.
