D. J. Nyman & Associates, Houston, Texas, Principal Engineer and Owner, March 1985 Present. Mitigation of natural and manmade hazards for oil and gas pipeline systems, nuclear power plants and industrial facilities. PROFESSIONAL PRACTICE Dr. Nyman has 30 years experience in the areas of structural engineering, stress analysis, engineering mechanics, failure investigations, testing, and instrumentation systems. His consulting services typically relate to pipelines, equipment, piping and structures, subjected to extreme or unusual load conditions, Page 1 of 10

2 including earthquake ground shaking, forced vibration and impulsive loading. His client base principally includes the pipeline industry, oil and gas production facilities, electric power plants, and heavy industry. Dr. Nyman s broad practice, related mainly to earthquake engineering, has required him to form multidisciplinary teams composed of leading practitioners and academicians nationwide having 20 to 50 years experience each to conduct various projects. Disciplines represented include earthquake geotechnical engineering, geology, fracture mechanics, nonlinear finite element stress analysis, structural design, pipeline design, equipment qualification, field measurement systems, and custom software development. Much of the project work requires consensus building among highly qualified project participants, including both project team members and client representatives. EXPERIENCE PROFILE An abstracted summary of Dr. Nyman s professional highlights follows: Trans-Alaska Pipeline. During his employment with the Trans-Alaska Pipeline System (TAPS) in the mid-1970's, Dr. Nyman was principally engaged in earthquake engineering. This effort involved the application of seismic design methodology to the pipeline system and pump station and terminal facilities. Included in this work was the seismic qualification of mechanical equipment, instrumentation, control systems, and computer hardware. He also conducted numerous engineering and design studies and interacted closely with regulatory agencies reviewing the design. As a consulting engineer, Dr. Nyman conducted a comprehensive program in the mid 1990s to revalidate the seismic design of the Trans-Alaska Pipeline System, a requirement that ensued from a Federal government audit of pipeline operation. This work consisted of the reassessment of seismic design criteria and preparation of a seismic design basis document, validation of operating systems seismic integrity, and evaluation of pipeline access road bridges. In 1998, Dr. Nyman directed a project to develop, fabricate, install and test a state-of-the-art computer-based seismic monitoring system along the 800-mile pipeline route. More recently, he assisted the Alaska Pipeline Project in the resolution of technical licensing issues related to the renewal of the pipeline right-of-way permit after 25 years of operation. Since the 2002 Denali Fault Earthquake in south-central Alaska, he has served as member of a seismic advisory panel charged with identifying post-earthquake investigations, engineering, and retrofits needed to assure continued seismic integrity of the pipeline system. The advisory panel is made up of nationally known experts two engineers and five geologists with combined experience totaling about 275 years. Currently, Dr. Nyman is directing a project to update seismic design criteria and seismic design specifications for TAPS and assisting TAPS with technical issues related to strategic reconfiguration of the pipeline system to improve operational efficiency at flow rates that are approximately one-half the amount accommodated by the original system design. He is currently collaborating with the USGS and the University of Alaska a new-generation seismic monitoring system for Alaska using the USGSdeveloped ShakeMap computer system for rapid post-earthquake determination of ground motion intensity. Sakhalin Island, Russia. Dr. Nyman currently provides seismic engineering consultation, guidance, and analytical support for design of a two pipeline projects on Sakhalin Island, Russia. These two engagements have included the development of a seismic design basis, analysis and design of active fault crossings for several sizes of line pipe, reconnaissance of a pipeline route for potential liquefaction and landslide hazards, and design of crossings of liquefaction zones. Many of the fault crossings involve reverse faults, which present considerable concern due to the compressive loading imparted to the pipeline at the crossing and the potential for buckling or wrinkling of the pipe wall. This work has required extensive communication and interaction with leading USA and Russian geologists and seismologists, as well as with oil company project management. Page 2 of 10

3 Large-Diameter Oil and Gas Pipelines in Azerbaijan, Georgia and Turkey. Dr. Nyman is currently engaged as seismic design consultant for a large diameter crude oil pipeline project in Turkey. For this project, he has conducted field reconnaissance of pipeline fault crossings, liquefaction and landslide areas, specified design requirements for seismic hazard mitigation, and performed design validation analyses of fault crossings. He is also conducting fault crossing evaluations and designs for crude oil and natural gas pipelines passing through Azerbaijan and the Republic of Georgia. In the field reconnaissance portion of this work, Dr. Nyman was the sole engineering representative on a consulting team composed of himself and six prominent geologists from Turkey, the United Kingdom and the USA. Offshore Baja California. Dr. Nyman is serving as a seismic consultant for preliminary engineering of a large-diameter natural gas pipeline crossing active faults offshore of Baja California and has directed the design validation of various crossing options. Other Pipeline Assessments. Dr. Nyman has conducted studies of the behavior of buried oil and gas pipelines subjected to large ground deformations associated with ground faulting, mining subsidence, intentional lowering and lifting, differential settlement, and mudslides. He conducted an evaluation of the effects of quarry blasting within 100-ft of a large diameter high-pressure gas pipeline. In this assignment, Dr. Nyman worked closely with a geotechnical engineering professor specializing in construction blasting vibrations. He has also investigated the effects of external loading on buried pipelines and designed a buried structure to protect a high-pressure gas pipeline from loads imposed by heavy mining equipment. Dr. Nyman has performed piping vibration measurement programs and analysis studies and has performed static and dynamic analyses of large diameter piping systems. He has also conducted studies and field measurements of the effects of wind-induced vibrations on above-ground pipelines on the North Slope of Alaska. Dr. Nyman has conducted a seismic vulnerability assessment of a large diameter crude oil pipeline that traverses the New Madrid seismic zone in the central United States. The objective of the study was to provide a general assessment of the seismic hazard for the pipeline and to chart a cost-effective course of action for improving its seismic resistance. Emphasis was placed on damage mitigation rather than on improved design or retrofit concepts that were likely to be cost prohibitive. Dr. Nyman recently provided consultation on seismic hazard mitigation for the conversion of an existing natural gas pipeline passing through the New Madrid area to liquid products service. These assignments required association with two nationally known university professors specializing in liquefaction hazard assessment. Dr. Nyman investigated the adverse vibration of large diameter piping in a high-pressure relief system. The investigation involved field measurement of dynamic response and pressure transients, dynamic response analyses, and hardware retrofit. He conducted a model subsidence test with soft clay soil to simulate thaw settlement conditions for pipelines underlain by permafrost or ice lens. He also developed instrumented steel pipe test piles for measurement of frost jacking forces in the Alaska. Penstocks and Surge Tanks. Dr. Nyman directed the investigation of the potential for brittle fracture of large diameter penstocks and surge tanks at four major dams on the Missouri River in Montana, North Dakota, and South Dakota: Fort Peck, Garrison, Oahe, and Fort Randall. Riveted construction was used at Fort Peck, and welded steel fabrication was used at the other three locations. The focus of the investigation revolved around the quality of the steel, welding and welding imperfections, and load rate. Two nationally known experts in brittle fracture, both professors at leading universities, were engaged as key consultants on this assignment. At one location, the load condition was exacerbated by the formation of thick ice inside the surge tanks during periods of winter temperature extremes, a condition that required special evaluation through a strain-gage measurement program. Offshore Oil and Gas Industry. Dr. Nyman has performed and supervised analyses of deepwater offshore platform connections and joints using linear and nonlinear finite element approaches. Page 3 of 10

4 Representative projects consisted of pile-to-jacket connections, launch cradles, and tubular joints. In conjunction with this activity, he conducted an instrumentation project that involved the monitoring of strains in a 700-ft water depth offshore platform during load-out and towing. Dr. Nyman has also served as a consultant for structural design of drilling equipment and substructures on offshore platforms to withstand seismic loading. Dr. Nyman directed the design an innovative 90-ton floating structure that was used to seal the bottom of a 39-ft diameter drill-ship moon-pool to permit dewatering for repairs without the need for a dry dock. This project was fast-tracked within a one-month period to permit repairs to be made in a coastal bay between drilling operations. This project included the stress analysis and engineering evaluation of a hang-off structure to hold a disconnected 7,000-ft long riser pipe above the seafloor during storm conditions. The project required intense, daily contact with oil company project managers and technical representatives, as well as the fabricator, who was cutting and welding steel plate almost in lock-step with the design. Nuclear Power. Dr. Nyman served for four years in an essentially full-time structural engineering consulting role on a multi-disciplinary team to assist a major nuclear power utility in its efforts to obtain an operating license. This assignment consisted of the review of design criteria and procedures for adequacy, review of design implementation, evaluation of proposed corrective actions, and preparation of reports to support licensing positions. In the end, virtually the entire plant was independently validated for design loads, and numerous retrofits were necessary to achieve regulatory compliance. Licensing was successful, and the plant has been in operation over 15 years. Professional Activities. Dr. Nyman has participated in professional activities related to seismic design of pipelines. During the early 1980's, he was principal investigator for a project to develop the first comprehensive guidelines for the seismic design of oil and gas pipeline systems. This work was performed during a three-year period under the auspices of the American Society of Civil Engineers with funding provided by the National Science Foundation. This seminal work is considered by many to be the authoritative guide for earthquake engineering of pipelines, and it has been used worldwide for nearly 20 years. In the past several years, Dr. Nyman has been engaged as a coauthor of new pipeline seismic guide scheduled for publication by the Pipeline Research Council of the Gas Research Institute in This document will serve to update the previous work published through ASCE. In the early 1990 s, Dr. Nyman was selected by the Federal Emergency Management Agency (FEMA) to draft a plan for the development of national earthquake standards for gas and liquid fuel lifeline systems. The plan was submitted to the Office of Management and Budget and for use as a guide for the development of seismic standards for oil and gas transmission lines, gas distribution systems, oil storage tanks, and refineries. Dr. Nyman also served as a member of an assessment team to review the effectiveness of the National Earthquake Hazards Reduction Program in mitigating seismic hazards to the built environment. His review scope pertained to lifeline systems (electric power, transportation, communications, energy pipelines, and water and sewer systems). In 2003, Dr. Nyman was a member of an expert panel formed by the National Research Council of the National Academies to develop a longterm research agenda for the Network for Earthquake Engineering Simulation (NEES). He recently completed a two-year term as a member of an external advisory panel for the Cornell University NEES test facility for buried pipelines. Page 4 of 10
