Multidisciplinary Assessments 

Managed and contributed to a third party independent assessment of cracking of a bilge keel on an FPSO. This project comprised of integrating assessments and inputs from several disciplines including, naval architecture, structural engineering, metallurgy, fatigue, and fracture mechanics and risk and reliability. 

Managed an independent review of the capability of a fabrication shop to simultaneously construct an extra module in addition to the one planned for an offshore drilling platform. This study examined the production risks, scheduler risks and safety risks associated with the side by side construction of two modules on a critical path to meet a weather dictated module deployment window. Inherent constraints considered included those imposed on account of sharing fabrication, quality control, material handling and human resources within the available indoor production space and ramping up production at a brown field idled facility with the need to hire suitable production crews. 

Served as the Project Manager for an independent evaluation of various internal apparent-cause and root-cause analyses for determining the source of unreliability in Reactor Recirculation Pump Seals installed at various boiling water reactors in the Exelon Corporation’s nuclear plant fleet. The results of this study, presented to senior corporate management, provided feedback on the root-cause analysis results and suggested process and equipment improvements. 

Served on a design assurance team assigned to perform a peer review of design documents for a West African natural gas pipeline being developed by a consortium of major oil companies. The work included performing an independent third-party review of documents related to the Pre FEED/FEED trunkline design activities and nearshore and onshore sections—as requested by the team—on a range of topics, such as the fatigue demand report, the Gas Export Regulating Manifold, and geotechnical assessments. The final report provided comments based on an integrated look at a project’s underlying assumptions, decision logic, alternatives, and forward plans. This evaluation, performed on behalf of an entity representing the investors, provided assurance of the design and suggestions for improvement to the oil companies. For example, evaluated design contractor’s update of requirements to be placed on monolithic isolation joint manufacturers to fatigue test their joints to ensure physical integrity under the specified loading conditions expected in an LNG pipeline network. The effects considered included metal fatigue, corrosion, degradation of elastomeric seals, and the cumulative impact of pressure transients on the joint’s structural integrity over its 30-year design life. This study included a review of the Monolithic Isolation Joint Specification, Data Sheet, and Supplier Data Requirements List (SDRL) to assess the impact of aging-related loss of strength and loss of corrosion barriers. 

Served as the project manager to determine the root cause of pump vibration at the Ginna Nuclear Station. This study provided the nuclear plant with the root cause, as well as with suggestions for design improvement and validation, prior to equipment replacement. 

Supported the initial economic evaluation and due diligence of a proposed integrated PTA/PET complex for an overseas investment firm. 

Analysis/Design Component Capability Calculations 

Contributed as a member of Failure Root Cause teams for several nuclear stations, including Ginna, H.B. Robinson, San Onofre, Grand Gulf, Millstone Unit 3, Catawba, Comanche Peak, Susquehanna, Nine Mile Point, Davis Besse, Pickering, Kori, Yeonggwang, Turkey Point, Shearon Harris, Laguna Verde, and Sizewell. These projects enhanced improved equipment reliability and plant availability. 

Example: Applied Computational Fluid Dynamic (CFD) methods to determine the root cause of valve failure by simulating non-testable conditions for a 24-inch feedwater lift check valve that was experiencing excessive wear. Analysis validated the hypothesis that the internal flow geometry was creating an unfavorable pressure distribution within the valve. An optimal disc position was then determined to ensure disc stability and closure on reverse flow without introducing excessive pressure drop during forward flow. 

Served as a project lead/projects specialist for check valve program development at San Onofre, Cooper, River Bend, Waterford 3, D.C. Cook, Callaway, and Wolf Creek. Contributor to INPO SOER 86-03 check valve application reviews for ANO 1, Clinton, Comanche Peak, South Texas, and Davis Besse. These projects generated technically rigorous and well-documented bases that facilitated the prioritization of the components for maintenance and condition monitoring programs. 

Example: Collected component- and system-level data including valve drawings; installation details; operating flow rate, pressure, and temperature data for all modes of plant operation; and valve maintenance histories. Comprehensive valve analyses were then performed on 1,100 check valves to quantify the rate of internal degradation, using the Check Valve and Analysis Prioritization (CVAP) methodology. Analysis results were used to prioritize valve maintenance, select condition monitoring methods, and schedule inspection intervals. Inspection recommendations included acceptance criteria for valve internals and use of non-intrusive diagnostic technologies. 

Served as a project lead for GL 89-10 Analysis of MOV design-basis calculations for all non-testable gate valves at Millstone Power Station Units 1, 2, 3, and gate and globe valves for Palo Verde, to determine thrust requirements and fulfill the requirements of NRC Generic Letter 89 10. This included the procurement of valve internal dimensions from valve vendors; the integration of operating temperature, pressure, and flow data; and the analysis of MOVs using the EPRI GATM methodology to determine thrust requirements. For valves that fell outside the technical specification, justification was developed to support designating the valve either “operable, but out of design” or “unpredictable/inoperable.” These projects enabled plants to develop data required to fulfill the regulatory requirement of ensuring sufficient operating margin. 

Performed Limitorque actuator fatigue life analyses for actuators loaded beyond their specified ratings, using the proprietary LTAFLA software for Carolina Power and Light. This evaluation enabled the utility to estimate the remaining fatigue life of motorized valve actuators. 

Performed detailed thermal stress analysis on a high-temperature, high-pressure steam throttle valve for the Department of Defense. This effort contributed to the design of a valve for a proprietary naval system. 

Contributed to the revision of EPRI/NMAC’s Application Guide for Check Valves in Nuclear Power Stations and provided sections on check valve hinge-pin wear and disc stud fatigue degradation. This document provided plant engineers with state-of-the-art guidance on the proper application of check valves. 

Responsible for all aspects of data gathering, verification, and document control supporting the 86-03 check valve application review for Florida Power and Light Company’s St. Lucie Units 1 and 2 and Turkey Point Units 3 and 4. This project enabled the identification of potential bad actors from the valve population, and a basis to plan their maintenance.

Responsible for all aspects of compilation and analysis of MSSV operating history data used to study the dependence of MSSV degradation on duration of plant operation at diverse power levels for Toledo Edison’s Davis Besse Nuclear Power Station. This effort supported the evaluation of the root-cause analysis of in-service degradation. 

Performed finite-element analyses of down-hole drilling mud motor sealed bearing assemblies of various sizes, and elastomeric hydrodynamically lubricated rotary shaft seals. Also performed structural and fatigue analyses of down-hole subs and bottom-hole assemblies. These projects supported the design of mechanical systems used in oil and gas exploration and production.

Laboratory and Flow Testing

Served as the Principal Investigator on the EPRI MOV PPM butterfly valve design, elbows, and scaling effect 10CFR50 Appendix B incompressible flow testing of butterfly valves, to quantify the effects of an upstream elbow on torque requirements, and to verify torque prediction and scaling equations used by the nuclear industry, published in EPRI TR-103257. This project culminated in the compilation of a comprehensive database on hydrodynamic torque coefficients of quarter-turn valves that is used by nuclear power plants to calculate the valve torque requirements.

Served as Project Lead for the EPRI MOV PPM Borg-Warner gate valves performance validation dynamic flow testing, to determine the root cause of high stem thrust requirements, published in EPRI TR-1032229V1. This project helped explain the cause of the gate valves’ anomalously high thrust requirements.

Served as Project Lead for the Kalsi Valve and Actuator Program (KVAP) model validation 10CFR50 Appendix B testing of quarter-turn valves to verify torque prediction and scaling equations, and to quantify the effects of upstream elbows on torque requirements. These incompressible and compressible flow tests were performed on a variety of valve types, including butterfly valves with symmetric, single-offset, and double-offset discs; ball valves of the full spherical and segmented type; and plug valves. This testing resulted in improved models to perform quarter-turn valve capability calculations for AOV JOG Program/RIS 2000-3 and GL 89-05 MOV JOG Periodic Verification programs.

Served as the Program Manager for the Nuclear Industry Check (NIC) valve trending program, to identify parameters that can be trended reliably to assess check valve internal wear and predict incipient failure. In consultation with the NEC Technical Advisory Group, developed a test plan, facilitated the flow-loop testing, and worked with TAG to prepare a final report for industry-wide distribution. This test program involved compressible and incompressible flow tests on swing, tilt, double disk, and piston check valves. This industry study helped nuclear power plant engineers develop plant condition monitoring programs.

Served on the project team responsible for Small Business Innovation Research/Nuclear Regulatory Commission’s (SBIR/NRC) Check Valve internal wear rate quantification Phase 2 test program. Performed tests and evaluated data gathered during the 18-month Phase 1 study of performance and prediction of degradation in swing check valves. The results formed the basis for the wear and fatigue methodologies provided in NUREG/CR-5583 and the NMAC Check Valve Application Guide, 5479 Rev. 1. This industry study resulted in the validation of first principal’s models and their use to prioritize the maintenance of check valves at several nuclear power stations.

Served on the project team for the EPRI Valve Design Separate Effects Test Program, with responsibility for the design and implementation of a closed-loop servo-hydraulic data acquisition and control system to simulate hydraulic loads on gate valve discs tested on the KEI gate valve design effects test fixture, described in EPRI TR-1032229V2. The test fixture developed under this study was used to evaluate key design features of gate valves in relation to their propensity to result in the unpredictable behavior of gate valves. The results of this study formed the basis of evaluation and modification of gate valves used in nuclear power stations.

Served as the Project Lead for several flow-loop tests that enabled clients to better quantify the performance of their valves and make better design choices, such as tests for Carolina Power and Light Company on 4- and 10-inch Westinghouse check valves to determine Vmin and disc stability. Designed special valve weld end adapters to mount 4- and 10-inch Westinghouse check valves on a KEI test flow loop.
