Prediction of flexible riser annulus environment

Challenge

Flexible risers can be subject to aggressive internal environments affecting fatigue and fracture performance and reducing the predicted service life. Currently, there is no generally accepted methodology between flexible riser manufacturers and end-users on how to calculate the composition of the annulus environment in a realistic way.

Benefits

Avoid excessive conservatism by understanding and accurately calculating the annulus environment.

Improve flexible fatigue riser design predictions and avoid premature riser replacement as well as fitness-for-service assessments for upset conditions.

Delivery

A validated computer based model to accurately predict annulus conditions for flexible risers transporting sour production fluids. The model will be used to define realistic (i.e. not over-conservative) environments for sour fatigue and fracture mechanics testing of armor wires.
