Abstract
A condition of a flexible pipeline may be monitored by scanning a section of the flexible pipeline with an ultrasonic scanner and using the ultrasonic scanner to produce a first ultrasonic signal that penetrates the section of the flexible pipeline and is used to create a set of condition data indicative of a condition present near or within an annulus of the flexible pipeline, the condition comprising pressure on or within the flexible pipeline. The set of condition data are used to determine if a flooded section of the flexible pipeline is present within the annulus, and a level of flooding within the annulus of the flooded section, by analyzing the set of condition data to locate areas where there are responses from a first layer of wire reinforcement proximate the flooded section, creating a wet data set using the set of condition data indicative of whether or not the flexible pipeline is most likely in a wet (flooded) condition, and creating a dry data set indicative of whether or not the likelihood is greater that a dry riser condition exists as opposed to a flooded riser.
