Pipeline Explorer
Description



Explorer gas pipeline inspection system

In developing Explorer, NREC performed requirements analysis, system simulation, design and engineering, prototype fabrication and field testing. NREC worked closely with natural gas distribution utilities across the country to arrive at a versatile and suitable design. The robot was extensively tested over the 2.5 year development period. This testing included week-long runs of multiple 8-hour days in live explosive environments for cast-iron and steel pipelines across the northeastern U.S.

The system is currently undergoing an upgrading phase, in which NDE sensors are being added and the system improved based on field trial results. Continued development of these new inspection methods will aid in maintaining the high integrity and operation reliability of the nation’s natural gas pipeline infrastructure.
