12、ed practice on movement of pipelines. A movement operation increases the longitudinal stress in the segment of the pipeline being moved. In most cases this additional stress has caused no significant problems. In 1978, however, a propane pipeline failed after being moved while in service. Although t

13、he movement may not have contributed to the failure, the incident demonstrated the need for uniform guidelines to ensure that the movement of an in-service pipeline is done with reasonable safety. Consequently, the American Society of Mechanical Engineers, the American Petroleum Institute, and the O

14、ffice of Pipeline Safety Regulation of the U.S. Department of Transportation jointly sponsored a study to establish guidelines for safely moving pipelines without taking them out of service. After the release of the “Guidelines for Lowering Pipelines While in Service” by authors at the Battelle Colu

15、mbus Laboratories, the American Petroleum Institute solicited qualified engineers responsible for the design, construction, and operation of petroleum pipelines to review the Battelle work and other available work and to prepare an industry recommended practice on the safe lowering and/or raising of

16、 in-service pipelines.The purpose of this recommended practice is to address the criteria, methods, values, and recommendations that should be considered in the design and execution of practical and safe pipeline-movement operations. However, it is impossible to foresee all possible pipeline-movemen

17、t situations or circumstances. This recommended practice is to be used as a guide for moving pipelines while they remain in service. It is not a rigid standard.This recommended practice is not intended to be an endorsement of moving pipelines as a method for addressing the safety of an existing pipe

18、line at a new road crossing, railroad crossing, foreign utility crossing, or any other crossing. It is merely intended to provide guidance to pipeline operators and contractors who choose the alternative of moving. This recommended practice has been revised to reflect that the methodology used in mo

19、ving pipelines can be used for other pipeline movement operations.API publications may be used by anyone desiring to do so.
