Abstract
We propose new real-time architectures for monitoring underwater oil and gas pipelines by using Underwater Wireless Sensor Network (UWSN). These monitoring architectures combine a real-time UWSN with nondestructive In Line Inspection (ILI) technology. A communication between UWSN and ILI tools adds a meaningful feature that allows the UWSN deliver crucial information regarding pipeline failures within minutes. Currently, there is no established communication system between UWSN and ILI. These suggested architectures will help reduce the pipeline defect detection time, dealing with corrosion, cracks, welds, and pipeline wall thickness through the improvement of data transfer from the pipeline to the processor. Moreover, the extraction of useful information and its timely delivery to the onshore main station will lead to decrease of issue occurrence.
