Improving the ability to detect small leaks prevent more severe accidents plays an extremely important role in safe operation of pipelines. To tackle issue low diagnostic accuracy associated with single sensors for detecting leaks, a multisource multimodal feature fusion method gas pipeline leak detection was proposed. First, collected data from multiple were transformed into 2-D time-frequency images input extraction network. Then, dual-information (DIF) module introduced, incorporating...
Natural gas pipelines are an important mode of transportation. How to quickly and accurately detect abnormal signals that occur during pipeline operation is crucial judging the status. In this article, signal detection method based on improved YOLOv7 (YOLO-PD) was proposed address low accuracy dependence manual segmentation scale setting in operation. First, a new refined channel attention (RCA) module enhance network feature extraction. Second, MaxPooling (MP) with RCA designed strengthen...
An innovative and complicated strand jack lifting technology was applied to floatover installation of DPP integrated topsides in South China Sea. Due initial failure lower the four outer support legs, an unfortunate chain events occurred thereafter, thus yielding a complete never happened history. A rescue operation carried out two following days successfully salvage both barge stranded inside jacket slot extraneous circumstances. This paper presents systems low-deck technology, as well...
Abstract. In urban areas, the None-Line-Of-Sight (NLOS) and Multipath (MP) signals are major issues degrading GNSS position accuracy. Signal reception type should be identified before correcting NLOS or MP induced errors. features, i.e., signal strength, change rate of received difference between delta pseudo-range rate, have been explored in classification. this letter, with aim to improve classification accuracy, we propose a new NLOS/MP/LOS method using correlator-level measurements....
At present, PE pipelines are widely used in urban gas pipeline networks. As safety is of great importance to the supply, this paper focuses on and reliability pipes during service. First all, analyzes aging factors materials failure forms mechanisms pipes. Second, performance testing methods summarized, including pressure tests, condition inspections, welded joint mechanical physical tests. In addition, life prediction for introduced analyzed. The applicability tensile experiments DSC based...
This paper makes a study on the technology of grouted clamp which strengthens and consolidates impaired pipe, in order to solve problem insufficient strength local damaged structure offshore platform. By building mechanics experimental platform for reinforcement pipeline, we made an experiment uniform axial compression pipeline installed clamp, getting data stress before after installation clamp. We use buckling theory under external pressure compress internal formula shows effects And...
To ensure safe ship navigation, true water depths should be deep enough with respect to the corresponding on a chart. Therefore, set of basic quality indices, including an index probability adequate depth, were developed evaluate digital depth model (DDM) navigational safety. In addition, these methods are proposed for assessing and percentage acceptable probabilities, deep-bias displacement. Theoretical analysis experimental comparisons presented in this paper demonstrate that defined...
