Pipelines present a unique challenge to monitoring because of the great geographical distances they cover, their burial depth, their age, and the need to keep the product flowing without much interruption. Internal corrosion is an important factor in pipeline integrity management. At present, the methods to assess internal corrosion in pipelines all have certain limitations. This paper describes the status in the development of a floating sensor system that can deposit at locations of water accumulation and communicate the corrosion information to an external location. Although the development and validation of the technology is not complete, the progress in the sensor development and wireless communication technology are described. Further research needs are identified.
