Introduction to Pipeline Leak Detection


Book Description

Pipeline spills occur as pipeline infrastructure ages and more hazardous products are transported. Regrettably, too many leak detection systems fail to detect these leaks, and other leak detection systems are ignored by the operators because they are unreliable. Thus, leaks that should have been small spills become disasters that cost pipeline owners millions of dollars. The key to the successful operation of pipeline leak detection systems is management commitment that assures the allocation of sufficient resources to the ongoing maintenance of leak detection systems and their supporting components. Every pipeline operator should consider a role for a leak detection champion who understands how their system works, continually monitors its performance, and supports the Pipeline Controllers. The leak detection system is not "fit-and-forget" and it requires ongoing management which is best achieved in-house with vendor support. Building a companywide leak detection culture, where pipeline leak detection is understood and valued from the top ranks to the field operators will reduce loss of containment incidents. "Introduction to Pipeline Leak Detection" explains the key leak detection technologies deployed to detect leaks on pipelines today in simple concise language that is easily understood by everyone.

Flow Modelling and Control in Pipeline Systems


Book Description

This book introduces novel methods for leak and blockage detection in pipelines. The leak happens as a result of ageing pipelines or extreme pressure forced by operational error or valve rapid variation. Many factors influence blockage formation in pipes like wax deposition that leads to the formation and eventual growth of solid layers and deposition of suspended solid particles in the fluids. In this book, initially, different categories of leak detection are overviewed. Afterwards, the observability and controllability of pipeline systems are analysed. Control variables can be usually presented by pressure and flow rates at the start and end points of the pipe. Different cases are considered based on the selection of control variables to model the system. Several theorems are presented to test the observability and controllability of the system. In this book, the leakage flow in the pipelines is studied numerically to find the relationship between leakage flow and pressure difference. Removing leakage completely is almost impossible; hence, the development of a formal systematic leakage control policy is the most reliable approach to reducing leakage rates.




Detecting Leaks in Pipelines


Book Description

Over the brief history of automatic leak detection, perhaps 40 years, there has been a great deal of experimentation and conjecture along with the application of real and meaningful science and technology. This is not unusual in a young field, but it has interfered with the development of a broad understanding of the underlying concepts and realities. This book places the need for leak detection on pipelines in a societal context using both a regulatory and a risk-based approach. It develops the applicable science, starting with first principles. It explores the technology available for implementation, shows how to estimate and monitor performance, and discusses how to maintain and ensure consistency over time. This book is an excellent reference for professionals who develop and apply leak detection systems, as it discusses the fundamentals of leak detection science and technology, including the mathematics on which the fundamentals are based. It also includes key information about threats pipelines encounter, along with the underlying concepts, capabilities, and limitations of leak detection technology. This information will be of great value to regulators as well as to petroleum industry executives, safety and technology managers, and operations managers.

Losses in Water Distribution Networks


Book Description

This is a best practice manual for addressing water losses in water distribution networks worldwide. Systems and methodologies are presented for improving water loss and leakage management in a range of networks, from systems with a well-developed infrastructure to those in developing countries where the network may need to be upgraded. The key feature of the manual is a diagnostic approach to develop a water loss strategy - using the appropriate tools to find the right solutions - which can be applied to any network. The methods of assessing the scale and volume of water loss are outlined, together with the procedures for setting up leakage monitoring and detection systems. As well as real losses (leakage) procedures for addressing apparent losses, by introducing regulatory and customer metering policies are explained. Suggestions are made for demand management and water conservation programmes, to complement the water loss strategy. Recommendations are made for training workshops and operation and maintenance programmes to ensure skills transfer and sustainability. The manual is illustrated throughout with case studies. Losses in Water Distribution Networks will appeal to a wide range of practitioners responsible for designing and managing a water loss strategy. These include consultants, operations managers, engineers, technicians and operational staff. It will also be a valuable reference for senior managers and decision makers, who may require an overview of the principles and procedures for controlling losses. The book will also be suitable as a source document for courses in Water Engineering, Resource Management and Environmental Management.




Pipelines 2011


Book Description

Proceedings of the Pipelines 2011 Conference, held in Seattle, Washington, July 23-27, 2011. Sponsored by the Pipeline Division of ASCE. This collection contains 135 peer-reviewed technical papers that discuss new solutions to some of the most critical infrastructure issues involving pipelines. The U.S. water and wastewater infrastructure systems are continuing to deteriorate. The recent economic downturn has increased the gap between current and required levels of funding. These serious financial constraints highlight the urgent need for creative and innovative solutions to improve our water and wastewater infrastructure systems. From the technical perspective, cost effective materials, proper planning, new design methods, innovative construction technologies, and advanced condition assessment technologies must be more aggressively developed, tested, and introduced to the industry. From the management perspective, optimal use of financial resources, smart and carefully crafted decision making processes on maintenance, rehabilitation and replacement activities must be made available, applied by and used by water and wastewater infrastructure agencies.




Evaluation of Pipeline Leak Detection Systems


Book Description

Leaking underground storage tank systems present an environmental concern and a potential health hazard. It is well known that leaks in the piping associated with these systems account for a sizeable fraction of the leaks. EPA has established performance standards for pipeline leak detection systems, and published a document presenting test protocols for evaluating these systems against the standards. This paper discusses a number of facets and important features of evaluating such systems, and presents results from tests of several systems. The importance of temperature differences between the ground and the product in the line is shown both in theory and with test data. The impact of the amount of soil moisture present is addressed, along with the effect of frozen soil. These features are addressed both for line tightness test systems, which must detect leaks of 0.10 gal/h (0.38 L/h) at 150% of normal line pressure, or 0.20 gal/h (0.76 L/h) at normal line pressure, and for automatic line leak detectors that must detect leaks of 3 gal/h (11 L/h) at 10 psi (69 kPa) within an hour of the occurrence of the leak. This paper also addresses some statistical aspects of the evaluation of these systems. Reasons for keeping the evaluation process "blind" to the evaluated company are given, along with methods for assuring that the tests are blind. Most importantly, a test procedure is presented for evaluating systems that report a flow rate (not just a pass/fail decision) that is much more efficient than the procedure presented in the EPA protocol, and is just as stringent.
