Pipeline Integrity Services

Specializing in Cathodic Protection


High Quality

High quality, thorough data collection and reporting. This is due to our data research prior to the field survey, good communication with field operations, and to the diligence of our Cathodic Protection Technicians.


New Technologies

Awareness and application of new technologies. Advancements in data collection and in data monitoring have resulted in better, more timely cathodic source monitoring, which in turn results in cost savings and less field exposure to incidents.


Timely Results

Timely and accurate survey reporting. Our routine turnaround time from survey completion to delivery of final report is less than 30 days.                                                                                                                                                               

Here is what some of our clients and contractors have to say...

Elliot and Associates have done an excellent job managing our company’s Cathodic Protection (CP) program since 2007. They have safely and capably handled annual CP surveys for 27 fields that range in age from new to 50+ years old. Also included in their services are tracking CP survey action items, taking regular rectifier readings, providing monthly status reports and completing installations of replacement and new anode beds.Their field personnel are very knowledgeable and organized, they have a strong work ethic and communicate well with our field staff.I’d highly recommend Elliot and Associates to any company that requires management of their CP systems.
