A specialized consulting engineering firm providing design, quality control, quality assurance, condition evaluation, testing, failure investigation, and repair and rehabilitation engineering services to clients throughout the United States and Canada.
CPI is proud to announce that Dan Gilbert has recently joined our Savannah, GA office as a Welding Specialist. Dan has a B.S. in Welding and Fabrication Engineering Technology from Pennsylvania College of Technology. Coupled with his formal training, Dan also brings years of practical experience as a welder. He will support the Mechanical Integrity service offerings through welding consulting, specification development, and welding process selection. Dan will also focus on field and shop fabrication quality verification to support local client needs
The Georgia office of Corrosion Probe, located just outside of Savannah, continues to grow its services and staffing. In January 2013, CPI expanded to a new office location to better serve area clients. Office growth can be attributed to outstanding personnel, great location and base clientele, and quality of project deliverables. The GA office focuses on mechanical and structural integrity of fixed equipment, primarily serving the pulp and paper industry. Three project engineers and two GA licensed professional engineers on staff provide mechanical, structural, materials, and welding consulting and engineering. This increase in growth coincides with CPI's advancement in tank and vessel fitness for service evaluations and repair planning efforts. Having the multi-disciplines in one office allows quick turnaround service and diversity to deliver expected results.
Kevin Krawiec co-authored an article entitled "FRP Odor Control Dome Failure", published in the Winter 2012 edition of the Journal of the New England Water Environment Association. The article presented the forensic engineering investigation performed when a fiber reinforced plastic dome covering a 70-foot diameter sludge gravity thickener tank failed and collapsed.
Bob Maley and Doug Sherman presented Deterioration of Wastewater Treatment and Collection System Assets: Knowing Where and How to Look (authored by CPI's Randy Nixon) at the recent Biosolids/Odor and Corrosion Conference put on by the Water Environment Association of Texas.
CPI Coating Consultants have been quite busy in 2013, solving lining/coatings problems, domestically from Key West, FL to Portland, OR and from Boston, MA to Phoenix, AZ, and internationally from Trinidad to Newfoundland. Digesters, wet wells, pump stations, and other structures, performing failure analyses, condition assessments, specification preparation, and project management.
Kevin Krawiec will be attending the Fall 2013 convention of the American Concrete Institute in Phoenix, Arizona, in October. He is currently serving as a member of Committee 563 Specifications for Repair of Structural Concrete Buildings, which is in the process of producing a standard specification for repair projects. He is also scheduled to be a speaker at the Spring 2014 convention in Reno, Nevada, presenting the coatings' selection chapter of the ACI Guide to Materials Selection for Concrete Repair.
Randy Nixon and Doug Sherman attended WEFTEC in Chicago in October. CPI staff regularly present papers and serve as instructors at workshops during the Water Environment Federation's annual Technical Exhibition and Conference.
The Massachusetts Water Resources Authority's Deer Island Treatment Plant (DITP) maintains 12 anaerobic, egg-shaped sludge digesters. The configuration of the digesters, while providing for efficient treatment of municipal wastewater residuals, also presents challenges to the performance of the internal inspection and condition assessment necessary for asset management. <more>
CPI is part of a team, led by Green International Affiliates, to perform a large-diameter steel and ductile iron water transmission pipeline condition assessment study for the Boston Water and Sewer Commission. Objectives for the project include developing corrosion-prevention methods and potential rehabilitation strategies for these critical water assets. The assessment includes stray current testing, pipeline continuity testing, and soil corrosivity analysis. While there are no immediate problems for the pipelines, the Commission is taking a proactive approach to avert any future concerns
CPI is currently working on a large asbestos-cement piping study for a large southwestern US city. The project objective is to help the city prioritize replacement of the water piping in a systematic way, based on technical data and statistical analysis. This study includes pH gradient testing, sulfate concentration analysis, EDS/SEM elemental analysis, and microscopy-all performed at CTL-to study failed pipe samples.
CPI and CTL are frequently involved at the design and scale-up phases in the development of new chemical processes. In some recent projects for conversion of wood and agricultural by-products to chemical feedstocks, CPI identified potential problems for the stainless steel materials of construction being considered. In selected cases, corrosion testing was performed by CTL to establish the corrosion limitations with test solutions from the pilot plant or benchtop at design temperatures. Inspection and analysis of damaged components from the pilot plant played an important role in addressing problems before they could occur in a critical start-up phase of the project. CPI's approach to solving such new problems was drawn from extensive experience in a broad range of industries, from food processing to petrochemical manufacture.
