Abstract:
A method and system for monitoring a flexible pipe, including an inline sensor system coupled to the annulus of the flexible pipe to detect corrosion of the flexible pipe. Also disclosed are method and system for monitoring an amount of water being accumulated in an annulus of a flexible pipe, including locating a pressure measurement system proximate to the annulus for measuring pressure of gas inside the annulus; controlling a flow of vent gas with a vent gas valve; positioning a flow measurement system upstream or downstream of the vent gas valve for measuring the flow of the vent gas when the vent gas valve is opened; and collecting with a microprocessor pressure and flow measurement data from the pressure and the flow measurement systems for determining the amount of water accumulated in the annulus based on the collected pressure and flow measurement data.
