Quimby & Associates has provided significant support to pipeline projects.  Most of the work has been relating to diagnosing problems with and designing repairs for existing petrochemical pipelines.  The following a few of the more significant projects:

Allison Creek Flow Enhancement. 
Conducted feasibility study and preliminary design for a siphon to be installed at Allison Lake, near Valdez, to enhance winter flow in Allison Creek.
PS1 Pipe Releveling, EWR P-4652A. 
Constructed mathematical models and executed analysis of deformed piping at Pump Station #1.
Valdez Pipe Settlement Investigation, EWR T-5259. 
Initiated investigation into possible settlement of 48" header pipe at the Valdez Terminal East Tank Farm.  Collected field data and conducted pipe stress analysis in an effort to estimate the extent of settlement before excavation was accomplished.
FGL Exposure Repair. 
This project required extensive support over two seasons.  Developed theory of mode of failure (included use of large deflection and material non-linear analysis), assisted in development of procedure to move and rebury 10" natural gas pipeline in permafrost in mid winter with the pipe still in service, and provided field support during reburial operations.
LPVR Main Header Piping. 
Provided structural evaluation of piping supports and design of new structure for a large diameter piping replacement project.
