Experience includes fatigue, fracture, and stress analysis of welded structures involving
pressure vessels, offshore platforms, oil and gas pipelines, bridges, and steel framed
buildings; fracture control procedures for pressure vessels; integration of fracture mechanics,
stress analysis, and nondestructive examination (NDE) for fracture safe design; and
materials selection procedures, welding methods and procedures, and properties of welded
joints.
Project work includes technology development for the Oman-to-India Gas Pipeline focused
on pipeline risk analysis, reliability, and welding and material issues; specifications for
quality control during line laying and issues related to subsea repair; analysis of liquids
pipeline rupture and leaks; design procedures for chilled natural gas lines; gas pipeline
failure analysis and line internal inspections; elastic plastic finite element analysis; the effect
of imperfections on structural integrity; significance and effect of residual and restraint
stresses on structural performance; measurement of residual stresses; selection of welding
procedures for avoiding hydrogen cracking; analyses of defects in linepipe; repair welds and
procedures; prediction of stress corrosion crack growth in austenitic piping; evaluation of
fatigue performance of deep water platforms; fracture controls for chilled natural gas
pipelines; review and evaluation of inspection records; reinspection programs; assessment of
document tracking systems; sampling programs for weld quality assessments; analysis of
inspection requirements for cast austenitic power plant components; development of life
extension programs for LNG plants; evaluation of inspection data for cooling water systems;
analyses of ERW pipeline failures; concrete intake structure damage monitoring schemes;
risk analyses of gas pipelines; risk prioritization of maintenance activities for chemical plants;
inspection program prioritization; licensing hearings; and litigation support.
Dr. Egan has worked on projects in numerous locations around the world including Europe,
the Middle East, Indonesia, South Korea, and Japan. Dr. Egan has worked on projects
involving analysis of project performance and project management including construction
management.
