Douglas J. Nyman, Principal Engineer

Douglas J. Nyman is a consulting engineer specializing in the mitigation of natural hazard effects on pipelines.  Most often this relates to the mitigation of permanent ground displacement associated with fault rupture, liquefaction, landslides and subsidence.  Dr. Nyman has over 35 years of professional experience and is recognized internationally as an expert in his specialty area.  His experience includes a career-long association with the Trans-Alaska Pipeline, initially as a member of the engineering staff and later as primary seismic engineering consultant. 

Dr. Nyman’s major strengths include development of project seismic design criteria; working with geologists to quantify fault rupture displacements, probabilities, and locations with minimum confusion and ambiguity; nonlinear analysis of pipeline fault crossings; nonlinear dynamic analysis of pipelines on sliding supports (“unrestrained” pipelines); and design to accommodate or avoid the effects of fault rupture or other forms of permanent ground displacement.  He also has extensive experience working with owners, operators and engineering contractors on major projects in a collaborative and advisory role to solve challenging problems in a timely manner.  His assistance is frequently requested on major pipeline projects in challenging frontier areas. 

Project highlights include recent roles as seismic consultant for two major oil and gas pipeline projects on Sakhalin Island, Russia.  In this role, Dr. Nyman evaluated more than 40 fault crossings, and performed field reconnaissance of liquefaction hazards.  He has also conducted fault crossing evaluations and designs for several oil and gas pipelines passing through Azerbaijan, the Republic of Georgia, Turkey and Papua New Guinea.  Dr. Nyman has also undertaken landslide hazard investigations for a copper slurry pipeline and natural gas and natural gas liquids pipelines in Peru, and geohazard screening assessments in Java and Papua New Guinea (PNG). 

Dr. Nyman has served on government-sponsored panels and committees engaged in the development of seismic design standards for lifeline systems.  He was the principal investigator for a National Science Foundation project to develop guidelines for the seismic design of oil and gas pipelines, which resulted in a seminal ASCE special publication in 1984.  He is a co-author of a recent update of that document prepared for the Pipeline Research Council of the Gas Research Institute. 

Douglas Nyman received a Ph.D. in Civil Engineering from the University of Illinois.  In 2001, he received the Distinguished Alumnus Award from the UI Dept. of Civil Engineering.  He also received the ASCE Charles Martin Duke Lifeline Engineering Award in 2002 and the ASCE Stephen D. Bechtel Pipeline Engineering Award in 2005.
