Corrosion Control and Cathodic Protection Systems Overview:

In accordance with TI 800-01 Design Criteria, Cathodic protection (CP) is a functional requirement for virtually all military projects involving new aboveground water tanks, direct buried or submerged structures, or the repair or replacement of similar existing structures.  A CP system shall be provided where applicable; project design and construction without considering CP is not acceptable.  TI 800-01 further requires the design of cathodic protection systems to incorporate guidance from TM 5-811-7 Electrical Design, Cathodic Protection, and to be provided as required by ETL 1110-3-474 Engineering and Design, Cathodic Protection.  Some of the specific structures, which are included in many of the projects designed and constructed by the Corps of Engineers, requiring design and installation of cathodic protection systems and other corrosion control measures, are listed in ETL 1110-3-474.  All CP designs and surveys must be performed by a “Corrosion Expert,” which is also defined in this ETL.  For a brief outline of these requirements for military projects, click here.

Additionally, corrosion control and cathodic protection systems are required on many of the Corps of Engineers civil works projects.  Structures such as lock miter gates, spillway gates, powerhouse intake gates, water storage tanks, as well as government owned and maintained buried metallic (or the metallic components of non-metallic structures) fuel tanks and lines, gas lines, etc., are examples of structures requiring the implementation of corrosion control measures.  For a list of some of the specific publications relating to corrosion control on civil works structures, click here.  In addition to these publications, paragraph 6.a of ER 1110-2-8157 Engineering and Design – Responsibility for Hydraulic Steel Structures, states the following requirement; “The Engineer shall ensure that the following types of design requirements are satisfied: strength, serviceability, fatigue and fracture, corrosion and wear.”

The Corrosion Control and Cathodic Protection Systems DX maintains state-of-the-art technical expertise regarding all-types of corrosion control and cathodic protection systems for use on Army, Air Force, and Corps facilities.  This expert knowledge includes, but is not limited to:  equipment, instrumentation, strategies and concepts for design and testing of cathodic protection systems; inspection techniques; specification development; failure analysis; formal training; consulting and

expert witness; as well as environmental, and safety issues relating to corrosion control.

Personnel at the center include electrical and electronic engineers, with NACE certifications as Cathodic Protection Specialists, equipped with many years of corrosion control and cathodic protection systems experience and expertise.  Mobile District has had extensive involvement in the initial development of TM 5-811-7, EM  1110-2-2704, MIL-HDBK-1004/10, and ETL 1110-3-474.  Additionally, the center supports HQUSACE in the development of criteria, research, and technology transfer upon request.  Mobile District provides support to HQUSACE in the technical revisions and updates of the following UFGS (Unified Facilities Guide Specifications) sections:  13110A,  13111A, 13112A, and 13113A.  The publications referenced in this paragraph, along with other pertinent publications relating to corrosion control and cathodic protection, are listed on the web page entitled, Standards, Laws, Criteria, & Publications.
