4.3.18.5. Corrosion Prevention and Control
The corrosion of military equipment and infrastructure within the DoD has been documented to cost approximately $23 billion annually. In addition to its significant financial impact, corrosion can also adversely affect system availability and ESOH. Therefore, it is extremely important to plan for and implement corrosion prevention and mitigation as early as possible in the acquisition life cycle (even prior to Milestone A) to minimize the life-cycle impact.
The execution of a program’s Corrosion Prevention and Control (CPC) planning should contribute to reduced corrosion vulnerability with lower life-cycle costs; and improved ESOH, maintainability, and availability.
Section 2228 of title 10, United States Code requires planning and execution of corrosion prevention and mitigation in DoD systems. Accordingly DoDI 5000.02 and 5000.67 require corrosion prevention and control planning for all acquisition programs across the life cycle. Elements of good CPC engineering include, but are not limited to, the following:
- Examination of legacy systems for possible corrosion design improvements
- Open and transparent assessment of alternative materials and processes that offer increased protection against corrosion
- Inclusion of CPC as a consideration in trade studies involving cost, useful service life, and effectiveness
- Incorporation of CPC criteria into relevant contractual documentation
- Identification, planning, resourcing, and acquisition of corrosion-related features for longevity, lowest total ownership cost (TOC), and maximum of effectiveness in support of the program
In the PDUSD(AT&L) memorandum, “Document Streamlining – Program Strategies and Systems Engineering Plan,” April 20, 2011, Program Managers are directed to capture all design considerations relating to CPC planning within the Systems Engineering Plan (SEP) with “hotlinks” to the program’s CPC Plan.
The Program Manager is responsible for ensuring resources, including corrosion engineering expertise, are available throughout the program and that corrosion performance is considered appropriately during design trades. The Systems Engineer, supported by CPC subject matter experts, is responsible for identifying corrosion concerns and developing mitigation strategies within the whole system design and operational construct.
All designated Acquisition Category (ACAT) programs are required to accomplish CPC planning across their life cycle, with ACAT I programs required to formally document this planning in an approved CPC Plan delivered at Milestones B and C. In addition, the DoD has developed the Corrosion Prevention and Control Planning Guidebook as a resource to assist the Program Manager, Systems Engineers, and other program staff in the development of a robust CPC program.
For all ACAT programs, CPC engineering should be reflected in various program documents, including, but not limited to:
- Technology Development Strategy/Acquisition Strategy (TDS/AS)
- SEP
- Test and Evaluation Master Plan (TEMP)
- Life-Cycle Sustainment Plan (LCSP)
- Contract/Request for Proposal (RFP)
- Program schedule – Integrated Master Plan/Integrated Master Schedule (IMP/IMS)
- Funding/budget
- Programmatic ESOH Evaluation (i.e., DFARS Subpart 223.73, Minimizing the Use of Hexavalent Chromium)
- System finish/process specification (add as a Data Item Description (DID) to Contract Data Requirements List (CDRL))
- System Performance Specification design, build, and testing requirements
In the contract and RFP, CPC planning should be addressed in some fashion in the technical content of each contract/RFP Section and subsection, including, but not limited to the Statement of Work (SOW), IMP/IMS, CDRL, and system performance specification (see DAG section 4.1.6. SE Role in Contracting).
