      Final Report (October 1, 2002 – December 31, 2004)
    • Abstract:
      The technical goal of this project, referred to as the Dual Array Project, was to develop new technology for non-invasive mapping of buried pipelines, down to depths of 10 meters or more, using modern electromagnetic sensors and signal processing. A major proposed innovation in the work was integration of the sensor arrays and software into a mobile system capable of mapping underground utility networks (and other buried infrastructure) efficiently over large areas. Ultimately, the goal is to have a non-invasive system that can produce an accurate infrastructure map of an entire urban or suburban utility network in digital form. This goal requires the development of new geophysical remote sensing technologies to create underground images down to the depths of most buried utilities in the United States and the development of software to extract features from the images to create digital maps that can be archived electronically – for example, in Geographic Information Systems (GIS). Key components of each of these goals were developed and demonstrated during the Dual Array Project. The technical work in the Dual Array Project was done by Witten Technologies, Inc., with contributions from Electromagnetic Instruments, Inc. (a division of Schlumberger), in development of new magnetic field sensors, and from Seknion, Inc., in analysis of the final field tests and writing of the final report. Consolidated Edison Company of New York, Inc. and South Central Connecticut Regional Water Authority (RWA) collaborated on the major field tests. Con Edison was also a cost-sharing partner on the agreement with U.S. DOT and helped with setting the technical goals for the project. The full documentation for the project consists of this final report and the nine quarterly reports supplied to U.S. DOT during the course of the project, which started in October 2002 and finished in December 2004. The final report is organized in five sections. The first three sections summarize the main results of the technical work carried out during the Dual Array Project. Section 1 provides an introduction and discusses the original technical concept and goals for the dual-array system and reviews briefly the history of the project and its accomplishments. Section 2 describes the different hardware and software components of the prototype EMI array, while Section 3 describes the key laboratory and field tests of the new EMI sensors and of the full sensor array. Section 4 covers issues related to a commercialization of technology developed in the Dual Array Project. Section 5 contains a financial summary of the project. Several appendices cover some of the more technical issues related to the project’s goals.
