Ryzyko związane z operacją instalacji rurociągu w projektach HDD

The success of the pull back operation of horizontal directional drilling can be increased by performance of a risk analysis. The problems, which might occur during a pull back operation, are varying from high pulling forces to uncompleted pull back operations and from slight coating damages to deteriorated pipelines. Consideration of all aspects of the combined pipeline soil behaviour formed the bases of a global risk analysis of the pull back operation. The risk analysis resulted in a series of risk reducing measures for future horizontal directional drillings.
