Mr. Ell has worked in the corrosion control field on a continued basis since 1981; with experience in all phases of corrosion control for buried and submerged structures. Particularly, electrochemical control of corrosion of rebar in concrete, marine structures, storage tank, and pipeline with gas, oil, water, and wastewater systems.Has experience with corrosion control material selection, design, installation, inspection, diagnostic testing. Mr. Ell is also familiar with marine structures such as vessels, docks, piling, sea wall, and concrete/rebar corrosion control. He is familiar with the procedures and instruments required to conduct field surveys related to cathodic protection systems, as well as specialized testing for stray interference in congested areas and induced AC on pipelines in power corridors.Additionally, Light Rail Transit support to include corrosion control design, construction management, construction support including continuity testing,electrical isolation, track to earth testing, diagnostics/trouble shooting and stray current monitoring/testing.Specialties: Mr. Ell is on the NACE International Technical Committee Light Rail Task group 297 & TEG024x. These committees are in communication with ASTM G165 committee to align our efforts with revised standards and test procedures.
