In pipeline transportation , pigging is the practice of using pipeline inspection gauges, devices generally referred to as pigs or scrapers , to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline.

Multisize pipelines are widely used in offshore oil and gas production system; however, the inspection and cleaning process for these pipelines usually are more complex. The pigs used in Santos basin, such as porcupine pigs for inspection and varipigs for cleanning, require some restricions, like maximum pig speed to guarantee a good cleaning effectiveness and, mainly, to guarantee the pig structural integrity. The main purpose of this work is to evaluate the simulation effectiveness to estimate pig total travel time and pig speed profile, therefore assuring the pig integrity during the pigging process in a gas network with many platforms interconnected. The analysys will compare total travel time and structural integrity of pigs after they arrive in final destination, given the lack of a velocity profile information in these procedures.

Smart Pigging Solutions

Smart pigging solutions — minimize risks, reduce costs and ensure the long term integrity of your pipeline. Pipelines are a safe, efficient method for conveying high value commodities, such as oil and gas. However, they are vulnerable to factors such as corrosion and deposits, which can reduce flow rates and cause expensive failures. Currently, to ensure pipeline integrity, cleaning pigs are used to remove deposits, and then intelligent in-line inspection ILI pigs are used to detect defects. Conventional ILI inspections cannot be performed frequently, as they are costly and disruptive. This means that pipelines can become susceptible to failure during the long period between inspections. Our smart pigging solutions enable your pipeline to be monitored for defect growth on a regular basis, minimizing costs and reducing risks to your operation.

Received: 4 December Accepted: 16 March Pipe cleaning is a common operation in the oil and gas industry. In this paper, the governing equation of the pipeline inspection gauge PIG, lowercase pig is commonly used speed is combined with the gas flow equations. The method of characteristics MOC is used to solve the transient equations of gas flow. And the process of a pig passing over an uphill section of a gas pipeline is simulated.

The pipeline inspection gauge PIG, lowercase pig is commonly used with a bypass valve is widely used in pipeline inspection because it operates at a low speed without reducing the flow rate. Understanding the dynamics of a bypass pig in a gas pipeline would contribute to the design of the pig and the control of pig speed. This paper deals with the dynamic model for the process of a bypass pig travelling through a hilly gas pipeline. The method of characteristics MOC is used to solve the equations of unsteady gas flow. The backward flow of the gas in the bypass valve and pipe is shown by a simulation of pigging for a hilly gas pipeline. Parametric sensitivity analysis of pigging in the horizontal gas pipe using a bypass pig is then carried out.

Хейл понимал, что говорит полную ерунду, потому что Стратмор никогда не причинит ей вреда, и она это отлично знает. Хейл вгляделся в темноту, выискивая глазами место, где прятался Стратмор. Шеф внезапно замолчал и растворился во тьме.

Если мы - охранники общества, то кто будет следить за нами, чтобы мы не стали угрозой обществу. Сьюзан покачала головой, не зная, что на это возразить. Хейл улыбнулся: - Так заканчивал Танкадо все свои письма ко. Это было его любимое изречение.

Джабба решил не обращать на него внимания. - Мидж, - беззвучно выдавил он, - черт тебя дери. В шифровалке все в порядке! - Телефон не унимался. Джабба принялся устанавливать на место новый чип. Через минуту его усилия увенчались успехом, а телефон все звонил и звонил. Христа ради, Мидж. Ну хватит .

Трудно даже представить, что происходит там, внизу. - Я пробовал, - прошептал Стратмор еле слышно. Ей еще не приходилось слышать, чтобы он так .
