Pipelines Division Technical Committees Working to Advance the Practice in Pipelines Engineering

Thursday, August 18, 2016

TC on Sustainable Design of Pipelines Sign At this year's Pipelines Conference in Kansas City , more than a dozen UESI Pipelines Division technical committees convened for meetings, along with the UESI Board of Governors; Pipelines Division Executive Committee; Surveying & Geomatics Division Executive Committee; and the Utility Risk Management Division Executive Committee.

The Pipelines technical committees that met were the As-Built Standards Committee , Design of Liners for Gravity Pipes, Pilot Tube & Other Guided Boring Methods , Pipelines Location & Installation, Trenchless Installation of Pipelines , and the Manual of Practice 112 - Pipe Bursting Committee . The task committees that convened were the Task Committee on Pipe Bedding, Backfill, and Trench Shoring Systems ; Seismic Design of Buried Pipelines ; Sustainable Design of Pipelines ; and Thrust Restraint Design for Buried Pipelines .

The task committees on Manual of Practice for Horizontal Auger Boring Projects (MOP 106), Manual of Practice for Water Pipeline Condition Assessment , and Manual of Practice for Water Pipeline Condition and Pressure Pipe Prioritization, Inspection, Assessment & Management , each held half-day workshops prior to the start of the conference.

Sri Rajah, Ph.D., P.E., P.Eng., ENV SP., F.ASCE , the Chair of the Pipeline Location and Installation (PLI) Technical Committee, which the task committee belong to, stated:

"The meetings at Pipelines 2016 were productive and the conference was another great conference. We thank all of the committee members for their hard work and dedication. They are advancing the vital work and practices in the field of Pipelines engineering."

Stephen Shumaker, P.E., M.ASCE , Chair of the Task Committee on Thrust Restraint Design of Buried Pipelines remarked:

"We have 45 members on this task committee.  The task committee has so far prepared a white paper, organized two workshops, and published 16 technical papers.  The committee is working on the refinements of an analysis model developed to study the thrust restraint design for all pipeline materials and the development of a draft manual of practice (MOP).  The target completion date for the MOP is later this 2016 to early 2017, for publication in 2017." 

Walt Schwarz, P.E., F.ASCE , Chair of the Task Committee on Sustainable Design of Pipelines stated:

"The SDP task committee has 40 members.  Based on the task committee work completed to date, one white paper (draft) and two (2) conference papers have been published and two (2) pre-conference workshops have been held (See completed work below).  The committee is currently finalizing the draft manual of practice for submission to the Blue Ribbon Committee for review.  

The committee has held working meetings the past two years, to further develop the chapters.  Due to the potentially contentious nature of the general subject, progress has been slower than expected, however it now appears that most of the conflicts have been resolved and the MOP is moving towards completion.  A Blue Ribbon Committee has been identified and contacted.  A qualifications package is being prepared for the Pipeline Location and Installation (PLI) Technical Committee for review and approval.  The target completion date for the MOP is late 2016, early 2017, for publication in 2017."

David Peters, P.E., M.ASCE , Chair of the Task Committee on Seismic Design of Buried Pipelines:

"This committee is being jointly supported by the Pipelines Division CTA/IRD. It was formed by the joint efforts of Pipeline Location and Installation Technical Committee and Infrastructure Resilience Division (IRD).  The objective of the task committee is to develop a new manual of practice on the subject of "seismic design of buried pipelines" for buried water/waste water pipelines.

This committee has more than 40 members consisting of national seismic experts, representatives from large utilities, representatives from different pipe material trade associations, and pipe manufacturers.  This group has completed two conference calls and will have an all-day meeting at the 2016 Pipelines Conference in Kansas City, on July 17th.  This group is currently working on finalizing an outline for the MOP.  The target completion date for the MOP is 2019.  This committee is also planning to have interim items delivered consisting of panel discussions at the 2017 and 2018 conferences and a final workshop at the 2019 conference." 

Marty McCabe, Ph.D., P.E., M.ASCE , Co-Chair of the Task Committee on Pipe Bedding, Backfill and Trench Shoring:

"This task committee conducted two national surveys on 'Current Practices on Trench Bedding, Embedment, Backfill and Shoring' and published the findings in two (2) conference papers.  The committee work is currently in the planning phases of developing a manual of practice (MOP) on the subject.  This committee has 8 members, and a proposal for reorganization of the committee officers is being considered by Pipeline Division ExCom.  The target completion date proposed for the MOP is 2019."

Stephen McKelvie, P.E., M.ASCE , Interim Chair of Task Committee on Revision of MOP 117 - Inspecting Pipeline Installation:

"The task committee is currently working on the update of the manual of practice (MOP) 117.  This group has developed a revised outline for the updated manual.  This committee has about 10 members, and a proposal for reorganization of the committee officers is being considered by Pipeline Division ExCom. The target completion date proposed for the MOP is 2019."

The MOP 106 workshop introduced a recently completed revision and update of ASCE MOP 106-Manual of Practice for Horizontal Auger Boring (HAB) Projects. The update is the result of four years of effort by the ASCE Pipeline Division Task Committee for the revision of MOP 106. The task committee members reviewed topics covered in the manual including HAB project planning, design, geotechnical investigation, construction, and documentation. The discussions included HAB system innovations, design examples, and case histories.

The Underground Pipeline Asset Management (UPAM) Technical Committee of the ASCE Pipelines Division established a Task Committee to develop a manual of Practice for Water Pipeline Condition Assessment. This committee has essentially completed its effort and the printed manual should be available shortly following the workshop. This workshop was provided by members of the task committee with the purpose of explaining the process of developing a condition assessment program, the issues associated with the various pipeline materials, tools available to provide assistance and the recommendations that can be anticipated from the program.

The workshop on Manual of Practice for Water Pipeline Condition and Pressure Pipe Prioritization, Inspection, Assessment & Management  addressed the key components of pressure pipe asset management: how to prioritize, inspect, assess, and manage (e.g. do nothing, periodic inspections, dig & replace, rehabilitate) pressure pipelines. The workshop focused on wastewater force mains and drinking water lines. Workshop speakers included the task committee members providing balanced information on pressure pipe asset management. The workshop concluded with a panel discussion where presenters and audience participated in an open forum.

The task committees plan to host and expand on additional workshops at the 2017 Pipelines Conference in Arizona .
