AGENCY: Research and Special Programs Administration (RSPA), DOT.
ACTION: Notice of meeting.
-----------------------------------------------------------------------
SUMMARY: RSPA invites the pipeline industry, in-line inspection
(``smart
[[Page 53485]]
pig'') vendors, and the general public to a quarterly performance
review meeting of progress pursuant to the contract ``Detection of
Mechanical Damage in Pipelines.'' RSPA wants the pipeline industry,
particularly that segment of the industry involved with in-line
inspection, including in-line inspection vendors, to be aware of the
status of this contract. This contract is being performed by Battelle
Memorial Institute (Battelle), along with the Southwest Research
Institute, and Iowa State University. The contract is a research and
development contract to develop in-line inspection equipment using
electromagnetic technology to detect and characterize mechanical damage
and stress corrosion cracking. Battelle's Program Manager will make a
presentation on the status of contract tasks, including a summary of
the activity and progress during the past quarter and the projected
activity for the next quarter.
DATES: The quarterly performance review meeting will be held on October
22, 1996, beginning at 9:00 am and ending around noon.
ADDRESSES: The quarterly review meeting will be conducted at the
Holiday Inn Capitol, 550 C Street, SW, Washington, DC.

SUPPLEMENTARY INFORMATION:
I. Background
RSPA is holding quarterly public meetings on the status of its
contract ``Detection of Mechanical Damage in Pipelines'' (Contract
DTRS-56-96-C-0010) because it recognizes that this in-line inspection
research is of immediate interest to the pipeline industry and in-line
inspection vendors. RSPA plans to make the results available on a
quarterly basis throughout the two- or three-year period of the
contract. The meetings will allow disclosure of the results to all
interested parties at the same time and provide an opportunity for
interested parties to ask Battelle clarifying questions concerning the
research.
The first meeting will be conducted on October 22, 1996, in
Washington, DC. Future quarterly review meetings may be held in
Columbus, Ohio (Battelle); San Antonio, Texas (Southwest Research
Institute); Ames, Iowa (Iowa State University); or Chicago, Illinois
(Gas Research Institute). Each of the future meetings will be announced
in the Federal Register at least two weeks prior to the meeting.
We want the pipeline industry, and in particular, that segment of
the industry involved with in-line inspection, to be aware of the
status of this contract. To assure that the industry is well
represented at these meetings, we have invited the major domestic in-
line inspection company (Tuboscope-Vetco Pipeline Services) and the
following pipeline industry trade associations: American Petroleum
Institute, Interstate Natural Gas Association of America, and the
American Gas Association to name an engineering/technical
representative, to attend the meetings.
II. The GRI/DOT Memorandum of Understanding
The Gas Research Institute (GRI) and the Department of
Transportation (DOT) signed a Memorandum of Understanding (MOU) on June
20, 1996, which formalized a partnership to further the mutual
interests of both organizations in providing public safety, and
environmental protection, and in reducing risks from gas transmission
pipelines. GRI is a cooperative research organization of the natural
gas industry. The MOU's objective is to define and formalize a
structure to exchange information and coordinate GRI's and DOT's
research programs, and to guide research in various areas involving
pipeline safety and environmental protection including nondestructive
testing, data analysis, risk management, damage prevention, and mapping
standards. The research contract RSPA has with Battelle is a
cooperative effort between GRI and DOT, with GRI providing technical
guidance.
III. The Contract
The Battelle contract is a research and development contract to
evaluate and develop in-line inspection technologies for detecting
mechanical damage and cracking, such as stress-corrosion cracking
(SCC), in natural gas transmission and hazardous liquid pipelines.
Third-party mechanical damage is one of the largest causes of pipeline
failure, but existing in-line inspection tools cannot always detect or
accurately characterize the severity of some types of third-party
damage that can threaten pipeline integrity. For example, although SCC
is not very common on pipelines, it usually appears in high-stress,
low-population-density areas and only when a limited set of
environmental conditions are met. Several attempts have been made to
develop an in-line inspection tool for SCC, but there is no
commercially successful tool on the market.
Under the contract, Battelle will evaluate and advance magnetic
flux leakage (MFL) inspection technology for detecting mechanical
damage and two electromagnetic technologies for detecting SCC. The
focus is on MFL for mechanical damage because experience shows MFL can
characterize some types of mechanical damage and can be successfully
used for metal-loss corrosion under a wide variety of conditions. The
focus for SCC is on electromagnetic technologies that can be used in
conjunction with, or as a modification to, MFL tools. The technologies
to be evaluated take advantage of the MFL magnetizer either by
enhancing signals or using electrical currents that are generated by
the passage of an inspection tool through a pipeline.
The contract includes two major tasks during the base two years of
the contract, and one major task (Task 3) being considered for an
option year to the contract:
Task 1 is to evaluate existing MFL signal generation and analysis
methods to establish a baseline from which today's tools can be
evaluated and tomorrow's advances measured. Then, it will develop
improvements to signal analysis methods and verify them through testing
under realistic pipeline conditions. Finally, it will build an
experience base and defect sets to generalize the results from
individual tools and analysis methods to the full range of practical
applications.
Task 2 is to evaluate two inspection technologies for detecting
stress corrosion cracks. The focus in Task 2 is on electromagnetic
techniques that have been developed in recent years and that could be
used on or as a modification to existing MFL tools. Three subtasks will
evaluate velocity-induced remote- field techniques, remote-field eddy-
current techniques, and external techniques for sizing stress corrosion
cracks.
Task 3, if done, will verify the results from Tasks 1 and 2 by
tests under realistic pipeline conditions. Task 3 will (1) extend the
mechanical damage detection, signal decoupling, and sizing algorithms
developed in the basic program to include the effects of pressure, (2)
verify the algorithms under pressurized conditions in GRI's 4,700 foot,
24-inch diameter Pipeline Simulation Facility (PSF) flow loop, and (3)
evaluate the use of eddy-current techniques for characterizing cold
working within mechanical damage.
A drawback of present pig technology is the lack of a reliable pig
performance verification procedure that is generally accepted by the
pipeline industry and
[[Page 53486]]
RSPA. The experience gained by the pipeline industry and RSPA with the
use of the PSF flow loop in this project will provide a framework to
develop procedures for evaluating pig performance. Defect detection
reliability is critical if instrumented pigging is to be used as an in-
line inspection tool in pipeline industry risk management programs.
The ultimate benefits of the project could be more efficient and
cost-effective operations, maintenance programs to monitor and enhance
the safety of gas transmission and hazardous liquid pipelines. Pipeline
companies will benefit from having access to inspection technologies
for detecting critical mechanical damage and stress-corrosion cracks.
Inspection tool vendors will benefit by understanding where
improvements are beneficial and needed. These benefits will support
RSPA's long-range objective of ensuring the safety and reliability of
the gas transmission and hazardous liquid pipeline infrastructure.

Associate Administrator for Pipeline Safety.
