Safe Pipeline transportation of energy resources is a major concern. Every Natural Gas Pipeline Operator’s primary objective is to operate and maintain pipeline network in such a way that it would continuously provide un-interrupted services to customers without any accidents which can adversely impact on the environment and reputation of the organization. Various surveillance methods are being used in Natural Gas Pipelines as a part of direct integrity assessment. Traditionally, surveillance is conducted by line walking and supplemented by vehicular over the linear corridor. This process involves various shortcomings in terms of efficacy, accuracy, cost, and safety. This method purely depend upon Inspector’s ability for detecting anomalies. It is in the interest of any operator to maintain the value of its pipelines and to protect them effectively against damage caused by third parties. As a result of global progress in high-resolution remote sensing and image processing technology, it is possible to use digital surveillance method for monitoring of pipeline Right of Use (RoU). Digital Surveillance is done using Remote Sensing and Geographical Information System (GIS) techniques. Remote sensing based pipeline surveillance refers to the monitoring and detection of changes on RoU and around pipeline networks. This paper elaborates on the development and implementation of a digital solution that uses images from satellites and Unmanned Aerial Vehicles (UAV) to detect instances of encroachments and third-party activities on Pipeline RoU. Such a solution provides capability of running advance analytics on captured images, and will enable to automate detection of anomalies which may often go un-noticed during manual inspection.

Agriculture is most important resources of any country worldwide which is a major renewable source and is dynamic. The study area selected was command area under Basavanna canal which is one of the canals to Tungabhadra river on right side bank. This selected canal for cropping pattern analysis has a command of 1240.00 hectare and is located at Vallabhpur, Bellary district. Basavanna canal has a designed discharge capacity of 125 cusecs for serving the cropping area. Every irrigation project has planned cropping pattern, the crop water requirement (CWR) for which is calculated based on Duty / Delta method. However due to growing population and increase demand for food products crop violation is found in every command leading to more irrigation. Remote Sensing (RS) and Geographical Information System (GIS) techniques have emerged as powerful tools for crop water management. Remotely sensed land use-land cover data was used for analysing the cropping pattern in the area and also to estimate the change in the cropping pattern. This study was performed using ArcGIS 9.3 and ERDAS 9 software. Crop water requirement was calculated using Modified Penman Equation for present cropping pattern. The study finds that, approximately 50% of water could be saved using modified Penmen method compared to crop water requirement calculated using Duty Delta method as adopted in project report and the same water may be diverted to meet other needs

New Criteria

Mechanical damage in the form of dents has emerged as a key safety concern for pipelines. In response, ASME B31.8, with assistance from GTI, undertook a detailed review of industry research and operating experience with respect to various forms of mechanical damage. Revised criteria for prioritizing and effectively repairing damage in natural gas pipelines were developed based on the findings. The criteria address plain dents, third-party type damage, dents that affect weldments, dents affected by corrosion, and strain levels associated with deformation of the pipe section. This paper discusses the generalities of the scientific findings and basis for the changes to the Code.

Desertification is one of the foremost environmental and social-economic problems facing the world. Thus, the observation and early detection of desertification is primary objective for scientific and policy organizations, with geospatial techniques as similar as Remote Sensing (RS) and Geographical Information System (GIS) being a candidate choice for the enlargement of monitoring systems. The present study purposes to assess the desertification caused by Aeolian sand deposits near Vedavathi River in a semi-arid region of Anantapur district, aided by temporal data of satellite imageries of past 28 years (1990 to 2018), were collected and processed. The extent of desertified land for the years 1990, 2000, 2010 and, 2018 is assessed, respectively about 28.22 Km2, 33.86 Km2, 46.30 Km2 and, 58.62 Km2. For the past 28 years, the Aeolian sand desertification is increased into the alarming rates with the land extent of 30.4 Km2.

Even though an excavation is not under the direct control of the utility operators, it is the main cause of third-party damage on the underground natural gas pipelines. Since the damage due to third-party excavation may lead to horrible consequences, preventative techniques that can reduce the third-party damage are needed. The purpose of this paper is to introduce an on-line monitoring system using accelerometer to detect a propagating acoustic pressure pulse that is produced from the third-party damage. Also, in order to verify this system, the corresponding field tests were performed considering many third-party damage sources(breaker, hammer drilling, etc.) and signal transmission ratio of each source. From the tests, signals developed by the third-party damage sources were successfully detected with the digital filter, which can distinguish external noises at the distance of 13km. Therefore, it is expected that the system can be used as a useful tool for the third-party damage monitoring of underground natural gas pipelines

The Individual

The acceptance criteria used in Reliability Based Design and Assessment (RBDA) are defined as a set of reliability targets (where reliability is defined as 1.0 minus the probability of failure). Because of the linear nature of pipeline systems, reliability targets are defined on a per km-year basis. Such targets are directly applicable to failure causes (or limit states) that are equally likely to occur anywhere along a segment of the pipeline (e.g. equipment impact or yielding/rupture of defect-free pipe under internal pressure). They are, however, not directly applicable for design and assessment situations involving limit states that apply at known specific locations. Examples include design for geotechnical loads on a particular unstable slope or integrity assessment of specific corrosion defects based on in-line inspection data. In previous work, reliability targets for natural gas pipelines have been developed on the basis of appropriate societal and individual risk criteria. This paper describes an approach to adapt these targets, and demonstrate compliance with them, for location-specific limit states. The approach is based on using separate checks to ensure that the individual and societal risk criteria underlying the targets are met. An example is included to demonstrate application of the approach to design a pipeline on an unstable slope.

Series Of Experiments

Acoustic reflectometry has been shown to be an effective technique for detecting defects, such as holes and blockages, in relatively short, single lengths of pipe. This paper discusses briefly the physical basis of the technique and then describes the results of a series of experiments that were designed to evaluate the suitability of using this approach for monitoring the health of natural gas pipelines. Such pipelines will typically be many kilometres long, have diameters of up to 1 m and may form part of a complex network of pipelines. Previous studies have demonstrated that acoustic reflectometry techniques can be used to detect pipeline defects in relatively small bore pipelines with lengths of several hundred meters. The results reported in this paper indicate that even when using fairly crude equipment, the technique can be successfully applied to detect defects in single pipelines and pipeline networks with large diameters and lengths exceeding 5 km. Although the results presented in this paper are not conclusive, they do provide the necessary justification for a second phase of experiments to be conducted to extend the scope of the technique further.

Independent Review

The introduction of a national gas access regime has coincided with a rapid expansion in the Australian market for gas transportation services. The threat of regulation and the approach of regulators, however, have influenced both the configuration of pipelines and the nature of transportation contracts. The recent introduction of reforms to the National Third Party Access Regime for Natural Gas Pipelines (Gas Access Regime), and to part IIIA of the Trade Practices Act 1974 (Cth), has the effect of introducing part but not all of the reforms recommended by the Council of Australian Governments’ Independent Review of Energy Market Directions, and the Productivity Commission’s Review of the Gas Access Regime. The principal amendments, relating to the insertion of an objects clause and the introduction of regulatory holidays for certain greenfield projects are also likely to influence the configuration of pipelines and the nature of pipeline contracts. These amendments are precursors to a major restatement of National Gas Access legislation that will, if enacted, have the effect of creating greater uniformity between the National Electricity Law and the regulatory environment that will apply to gas, but, will also open up the opportunity for pipeline owners and operators to submit to a lighter form of regulation.

Future Events

In flood-prone areas, the delineation of the spatial pattern of historical flood extents, damage assessment, and flood durations allow planners to anticipate potential threats from floods and to formulate strategies to mitigate or abate these events. The Chenab plain in the Punjab region of Pakistan is particularly prone to flooding but is understudied. It experienced its worst riverine flood in recorded history in September 2014. The present study applies Remote Sensing (RS) and Geographical Information System (GIS) techniques to estimate the riverine flood extent and duration and assess the resulting damage using Landsat-8 data. The Landsat-8 images were acquired for the pre-flooding, co-flooding, and post-flooding periods for the comprehensive analysis and delineation of flood extent, damage assessment, and duration. We used supervised classification to determine land use/cover changes, and the satellite-derived modified normalized difference water index (MNDWI) to detect flooded areas and duration. The analysis permitted us to calculate flood inundation, damages to built-up areas, and agriculture, as well as the flood duration and recession. The results also reveal that the floodwaters remained in the study area for almost two months, which further affected cultivation and increased the financial cost. Our study provides an empirical basis for flood response assessment and rehabilitation efforts in future events. Thus, the integrated RS and GIS techniques with supporting datasets make substantial contributions to flood monitoring and damage assessment in Pakistan.
