THE PURPOSE. Consider the use of special purpose vessels with a dynamic positioning system. To conduct observations and research operation electrical power systems such for existence problems in them that affect performance technological operations. propose methods means aimed at eliminating situations processes adversely shipboard when laying pipelines. METHODS. For observation research, unifi...

Large deformation causing damage due to uplift force is generated in buried pipeline located in shallow trenches in marshes and saturated soils. In this paper, existing common methods of pipeline anchorage are discussed and considering advantages and disadvantages of these methods, a new method of pipeline anchorage are studied and presented. In this new developed method, geo-textile materials ...

To achieve the principles of reduction, resource, and harmless disposal domestic waste, circular economy prolongs life cycle resources by converting waste into renewable through sorting, recycling, other ways. There are still noticeable problems in recycling China, such as poor classification low recovery rate resource-based with no or economic value. In this paper, Van Waden’s seven-dimensiona...

offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. a safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. while the cost...

background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...
