Kurt Lawson is director of Facility & Pipeline Services for DNV Columbus. While at DNV Columbus, The Ohio State University, and Armco Steel, Inc., Mr. Lawson has had extensive experience and training in corrosion science. He has specialized in the application of AC and DC electrochemical techniques to aqueous corrosion, soil corrosion, the corrosion of reinforced steel in concrete and cathodic protection. He has performed work for developing new and innovative electro-chemical test methods involving the application of polarization resistance methods for cathodically protected carbon steel in soil and the application of electrochemical impedance spectroscopy and harmonic impedance spectroscopy for cathodically protected carbon steel in concrete containing chloride ions and condenser water boxes. Other work includes evaluation of magnesium sacrificial anodes for cathodic protection; evaluation of passivating treatments and coating systems for automotive brake line tubing; evaluation of long-term atmospherically exposed coated building panels; assessment of microbiological influenced corrosion and chloride induced pitting in natural waters; and cathodic protection assessments on buried pipelines.
He has also conducted extensive research in underground corrosion and corrosion control, including such topics as the use of coupons for monitoring cathodically protected structures, cathodic protection in DC stray current areas, and various programs on pipe-soil potential measurement techniques and analyses.
Mr. Lawson has over fifteen years of field experience in the corrosion testing and evaluation of buried structures including reinforced soil structures, pilings, reinforced concrete structures, and cathodically protected tanks and pipelines. Work on these structures has covered a wide range of techniques including basic potential surveys, application of advanced AC and DC electrochemical methods, advanced potential surveys utilizing digital storage oscilloscopes, and complex finite element computer modeling of cathodic protection systems and their effectiveness. Other field work includes the inspection of flue gas desulfurization systems; the design, installation, and evaluation of novel test probes for the monitoring of the corrosion within various process systems; the design installation and evaluation of an atmospheric test program for establishing causes of spotting on automotive finishes; the design, construction, and installation of test panels for evaluating candidate materials for fresh water lock and dam construction; and general metallurgical and failure analyses of materials.
