We are confident these tests have helped provide reassurance and technical evidence to the public on the safe operating condition of Line 9. The safe operation of the pipeline is our top priority.
The Turkish parliament recently ratified the document, which provides a legal framework for the construction and operation of the pipeline.
The 4-to-0 decision on Monday had been widely expected since the commission's staff concluded in March that the construction and operation of the pipeline would not pose significant environmental hazards.
The staff members, who held hearings last fall on a draft report in which they recommended approval of the project, have ultimately deemed construction and operation of the pipeline "an environmentally acceptable action".
However, continuous leak-detection methods of require a lot of manpower, marterial resources and financial supports, while other detecting activities break the normal operation of the pipeline.
Parameter studies reveal a limit to the temperature difference for safe operation of the pipeline, in the sense that for higher temperature differences a localised buckling mode has lower total energy than the straight unbuckled pipe.
The excessive lateral deformation from lateral buckling may risk safe operation of the pipeline due to local axial strains that potentially could be severe enough to cause fracture failure of welds or collapse of the pipeline.
If a long-distance gas pipeline is unavoidably buried under a planned high-filling road, the high fill subgrade setting will result in the change of the pipe's mechanical shape and the local stress concentration on the pipe, which will pose threats to the safe operation of the pipeline.
This paper discusses the principles and criteria for the zonation and assessment of the frozen-ground environments and conditions of engineering geology for the design, construction, and operation of the pipeline system based on an extensive and in-depth summary and analysis of the survey and exploration data.
The DEIS concluded that construction and operation of the pipeline would have minimal impact to the environment.
