Abstract

Pipe-bursting is a trenchless pipeline replacement method that has primarily been used in the wastewater industry to replace deteriorating sewers. Originally, however, this technology was brought to the US in the mid-1980s as a method for the replacement of gas mains. The process is now being rediscovered by gas utilities for use in specific situations as a means of distribution system renewal. Cinergy Corp. has a program of examining and testing new gas main installation and rehabilitation methods under actual field conditions. As part of these efforts, Union Light Heat and Power Co., a division of Cinergy serving the Covington, KY area, recently used pipe-bursting technology to replace a 400-foot section of 8-inch diameter cast iron main. The new line was then put into service as an additional feeder to customers in the Covington service area. Cinergy engineers have determined that to be considered for pipe-bursting, a main should be the end of a one-way feed or in a two-way feed where there is a sufficient amount of gas to supply customers on other parts of the line. In most cases, the company does not shut off customer service for more than one day`s work, otherwise a bypass system maymore »« less

Trenchless rehabilitation: Which choice for gas distribution pipe replacement?

Journal Article Kramer, S; Gauthier, S - Pipeline and Gas Journal

Replacement or rehabilitation of deteriorating gas piping currently relies largely on open-cut excavation or pipe insertion. Open-cut replacement is satisfactory for communities where adverse environmental impact can be tolerated and road closures and traffic delays are kept to a minimum. However, most of the systems in need of replacement/rehabilitation are in urban areas where environmental impact, traffic delays, and site restoration costs are costly. With these parameters in mind, the Gas Research Institute (GRI); and its member organizations designed a research program to test and evaluate promising trenchless technologies for potential use in gas distribution rehabilitation projects. The programs`s goalsmore »« less
Trenchless rehabilitation of buried pipelines via cured-in-place pipe -- an environmentally friendly solution

Miscellaneous Baldwin, R; Sorrell, P

Refiners and petrochemical producers are faced with a number of issues related to aging infrastructure in their processing facilities. Many of these facilities were initially constructed in the 1960s or earlier and have a large number of plant-wide utilities, general facilities and underground piping systems that are at least 30 years old. Many underground piping systems are approaching the end of their useful life which can be extended only by substantial reconstruction or rehabilitation. This paper will focus on the rehabilitation of underground effluent piping systems such as process sewers, contaminated storm sewers, low-pressure effluent force mains and sanitary sewers.more »« less
Evaluation of Trenchless Installation Technology for Radioactive Wastewater Piping Applications

Technical Report Robinson, Sharon; Jubin, Robert; Patton, Bradley; ...

The U.S. Department of Energy (DOE) Office of Environmental Management (EM) cleanup mission at Oak Ridge National Laboratory (ORNL) includes dispositioning facilities, contaminated legacy materials/waste, and contamination sources and remediation of soil under facilities, groundwater, and surface water to support final Records of Decision (RODs). The Integrated Facilities Disposition Project (IFDP) is a roughly $15B project for completion of the EM mission at Oak Ridge, with a project duration of up to 35 years. The IFDP Mission Need Statement - Critical Decision-0 (CD-0) - was approved by DOE in July 2007, and the IFDP Alternative Selection and Cost Range -more »« less

Evaluation of trenchless renewal systems and techniques for gas distribution mains. Final report, August 1993-March 1995

Technical Report Kramer, S

The report evaluates promising trenchless technologies for their potential use in rehabilitating or renewing gas distribution pipes. Of the commercially available trenchless renewal options, the U.S. gas industry is primarily using the sliplining method of inserting a new pipe within the old pipe and to some extent pipe bursting. Other trenchless methods have seen little use in the U.S. even though many of these technologies have proven successful and cost-effective for gas utilities have proven successful and cost-effective for gas utilities in Europe and Japan.
Do not disturb the animals! or, how Con Edison saved $300,000 using a trenchless technology to renew 3,000 feet of leaking gas main at the Bronx Zoo

Journal Article Bufe, M - American Gas

Every leaking gas main presents a challenge. But when that leaking main follows a series of sweeping bends on its route through North America`s largest urban wildlife park, it presents a special challenge. That was the situation Consolidated Edison Company of New York Inc. recently faced when numerous leaks were discovered along 3,000 feet of a 95-year-old, 12-inch cast-iron main that winds through New York City`s Bronx Zoo. Con Edison knew it needed a long-term solution to this increasingly common problem. Thanks to the cooperative efforts of the utility`s operations and research departments and the Gas Research Institute (GRI), Conmore »« less
