Abstract Cross-country pipelines are the safest mode of transportation for petroleum products. A typical hydrocarbon multi-product cross-country pipeline network consists of Dispatch station, cross-country Pipeline, Intermediate Pump Stations, Sectionalizing Valve Stations, intermediate pigging stations and Receipt Stations. Dispatch station, Intermediate Pump Stations and Receipt stations are manned stations to meet the operational and maintenance requirements in the pipeline network. Since pipelines operate round the clock, operations work force are required on 24 × 7 basis at these control rooms. Typically, work force expenses account for more than 25% of total operating cost. Cross-country pipelines are often laid in areas away from Urban and Industrialized areas. Intermediate Booster stations are also mostly located in remote areas. The work force operating these stations have to stay in hardship locations to ensure pipeline operations are unhindered. In order to optimize the work force requirements at Intermediate Pump stations and to ensure seamless and safe operations, it is proposed to construct Smart pump stations. The smart pump stations are intelligent enough with state of the art instrumentation to be monitored / controlled / operated from a remote controlling station which is a non-hardship location. The smart pump stations are designed such that it will have self-sufficient systems which will require minimum human interface from remote controlling stations. HPCL has implemented the smart pump station design philosophy in its ongoing Vijayawada Dharmapuri Pipeline project wherein two Intermediate Pump (IP) stations viz. Donakonda & Kalakada are designed and are being constructed as smart pump stations which are being completely automated and will be remotely monitored / controlled from remote controlling stations at Vijayawada & Kadapa respectively. Design philosophy of Smart Stations entails developing a completely new and a tailor made design philosophy for Process, mechanical, Electrical, Instrumentation, cathodic protection system, SCADA, Telecom & allied systems, fire & safety and accordingly getting all the equipment selected / manufactured / installed / commissioned.

The process to deregulate the pricing of petroleum products kept evolving until July 2015 where fuel prices were completely deregulated, and managed by Bulk Distribution Companies (BDCs) and Oil Marketing Companies (OMCs) under supervision of the National Petroleum Authority (NPA). This phase of the deregulation policy ended the subsidy regime. Deregulation policy was implemented to help stabilise price hikes. As a land mark policy, deregulation has implications. This research assessed perspectives of commercial drivers on deregulation of diesel and petrol pricing in Ghana using Tarkwa as a test case. The methods employed include field visits to lorry stations in Tarkwa; interviews and questionnaire administration; and statistical analysis of data. The study revealed that majority of commercial drivers are aware of the implementation of the deregulation policy in Ghana but do not understand its effects. All the commercial drivers revealed that there are different prices of diesel and petrol at pump stations. Majority were of the view that their choice of a pump station depends on both the price and quality of the fuel, and the proximity of the pump station to their operations. All commercial drivers asserted that the deregulation policy has negatively affected their business. It is therefore recommended that the NPA should insist on price reduction nationwide when prices of fuels are reviewed downwards and also ensure that the right information is efficiently communicated to consumers of petrol and diesel in Ghana especially commercial drivers to minimise the risks of anxiety.

Aiming at the situations that pumps of the same model are used in most pump stations and the price of frequency converter is too high, the reasons are analyzed for the low efficiency of pump assembly operating under the single frequency converter configuration condition. In multipled pump assembly equipped with pumps of the same model, adding an extra pump operating as a transitional pump whose maximum flow rate is half of the previous ones’ will reduce variable-speed pump’s speed regulation ratio. According to this, a model for optimising operation of pump station is constructed with the minimum shaft power being objective function and solved by simulated annealing genetic algorithm. And then a comparison analysis about energy consumption and economical efficiency is made toward these three speed regulation strategies. Energy consumption analysis results indicate that single speed regulation with transitional pump consumes a little more energy than that of all speed regulation, while economical efficiency analysis results show that it cost only one twelfth of all-speed-regulation in extra investment and its payback period is one eighth of the latter’s. The effect of energy saving of this strategy of speed regulation is obvious and solves well the problem that pump station equipped with the same model of pump operates at low efficiency when equipped with a single frequency converter.

The Impact

The development of natural gas pipeline network towards larger scale and throughput has urged better reliability of the pipeline network to satisfy transportation requirement. Previously, studies of optimizing natural gas pipeline network have been mainly focused on reducing operating cost, with little concern on the reliability of pipeline network. For a natural gas pipeline network with a variety of components and complicated topology, a multi-objective optimization model of both reliability and operating cost is proposed in this study. Failure of each component and the state of pipeline network under failure conditions are taken into account, and minimum cut set method is employed to calculate the reliability of the pipeline network. The variables to be determined for the optimization objectives are the rotating speed of compressors and the opening of valves. Then the solving procedure of the proposed model is presented based on Decoupled Implicit Method for Efficient Network Simulation (DIMENS) method and NS-saDE algorithm. The validity of the optimization model is ascertained by its application on a complicated pipeline network. The results illustrate that the optimization model can depict the relative relationship between reliability and operating cost for different throughput, by which the operation scheme with both satisfying reliability and operating cost can be obtained. In addition, the customer reliability and the impact of the failure of each pipeline on the whole network can be evaluated quantitatively to identify the consumers and pipelines of maintenance priority. The pipeline network reliability can be improved through proper monitoring and maintenance of these consumers and pipelines.

Wu-Hao-Gou pump station is one of many pump stations being going to build in order to meet the increasing need of water supply in the Shanghai city. Owing to limited building site, large discharge and multi water outlet direction, the design and arrangement of hydraulic structure become more difficult than usual pump station. In the paper, CFD method is used to simulate the whole inlet flow field and improve hydraulic performance of the pump station. Firstly, the whole hydraulic structure geometric model, combined by Penstock, transition passage, diversion channel, fore bay, suction bay and suction pipe, is built and subdivided with unstructured mesh. Secondly, inlet flow field of the original pump station scheme is simulated and analyzed with the SIMPLEC algorithm, the realizable k-ε turbulence model and the symmetric boundary hypothesis on the free surface. Thirdly, the better scheme is calculated with the same numerical method after taking some effective measurements. Lastly, the better scheme is simulated with the VOF model, as well as the numerical results are compared with the above symmetric boundary hypothesis model to reveal the fact that the main flow character is similar but some flow details differ between the two free surface model. Then, the physical model experiment will be performed to verify the better scheme in the next step.

Abstract Pipeline transport is a commonly utilised method for moving petroleum products from one location to another. It is considered as one of the safest, fastest, and most reliable options for transporting petroleum products. However, the use of pipelines for oil transport is associated with the risk of pipeline failure, a challenge caused by a range of factors including corrosion, ignition of natural gas, accidental damage during excavation work, lapses in maintenance as well as vandalization. Most prevalent in Nigeria is the menace of pipeline vandalization and oil thefts which is a critical factor responsible for most pipeline failures across the country. Varied efforts aimed at addressing the problem of vandalization and oil thefts in Nigeria have, over the years, yielded minimal benefits. Therefore, this review investigates the usefulness and suitability of artificial intelligence (AI) for securing Nigeria’s pipeline network. The review focuses on summarizing available evidence on the use of some relevant AI components such as Image Analytics, Convolutional Neural Network (CNN) as well as Edge-Based AI Solutions, for securing oil pipelines. Based on the findings of case studies and other primary research materials utilized in this review, this paper concludes that while there is need for further research on the subject, AI offers a promising and useful solution to Nigeria’s endemic challenge of pipeline vandalization and oil theft. This is as AI promotes early detection of illicit activities on pipelines and can relay signals to appropriate authorities on the need for urgent action. The use of AI in securing Nigeria’s vast pipeline network will not only minimize the economic losses caused by vandalization but will equally contribute towards mitigating the adverse environmental impact of oil pipeline vandalization in Nigeria.
