Mechanics Of Offshore Pipelines

Mechanics of Offshore Pipelines, Second Edition, Volume One: Buckling and Collapse gives engineers fundamental knowledge on principles surrounding the mechanical behavior of pipelines and long tubular structures in the oil and gas industry. Addressing common challenges pertaining to buckling and collapse under various offshore loads, the authors go through each challenge experimentally, with supporting and analyzing data to present the main limits encountered. Helpful to both the practicing engineer and the graduate level, the combined effort of analysis supplemented with numerical modeling helps engineers design procedures and guidelines to reproduce the best solution or solve problems using a nonlinear finite element code. Custom formulations are also included to help users gain a deeper understanding of each challenge. Rounding out with helpful appendices, including a glossary of terms, this book continues to deliver critical research and data to engineers that need to design, install and maintain efficient and safe offshore pipelines. Updated to include more practical aspects, such as failure of corroded pipes under external pressure and response of bi-material under bending Delves into cost-effective materials and installation techniques Covers guidelines, practicing methods and recommendations on maintenance and design Recommended as the "bible" for offshore pipelines Explains the full spectrum of classical challenges, such as inelastic structural mechanics and the newest technological demands

Offshore oil and gas production was conducted throughout the entire 20th century, but the industry’s modern importance and vibrancy did not start until the early 1970s, when the North Sea became a major producer. Since then, the expansion of the offshore oil industry has been continuous and rapid. Pipelines, and more generally long tubular structures, are major oil and gas industry tools used in exploration, drilling, production, and transmission. Installing and operating tubular structures in deep waters places unique demands on them. Technical challenges within the field have spawned significant research and development efforts in a broad range of areas. Volume I addresses problems of buckling and collapse of long inelastic cylinders under various loads encountered in the offshore arena. Several of the solutions are also directly applicable to land pipelines. The approach of Mechanics of Offshore Pipelines is problem oriented. The background of each problem and scenario are first outlined and each discussion finishes with design recommendations. * New and classical problems addressed - investigated through a combination of experiments and analysis * Each chapter deals with a specific mechanical problem that is analyzed independently * The fundamental nature of the problems makes them also applicable to other fields, including tubular components in nuclear reactors and power plants, aerospace structures, automotive and civil engineering structures, naval vehicles and structures

Buckle propagation is a problem unique to offshore pipelines, in which the local collapse of a locally weakened section of the pipe initiates a collapse that propagates at high speed catastrophically flattening the line by kilometers. The lowest pressure that can sustain the propagation of the collapse, the propagation pressure, is only a small fraction of the collapse pressure of the intact pipe. The large difference between these two pressures requires that pipelines be designed on the collapse pressure, and the extent of the potential catastrophic damage suffered is limited by the periodic introduction of buckle arrestors to the line. Volume 2 of the book series Mechanics of Offshore Pipelines addresses the major aspects of buckle propagation including its initiation, establishment of the propagation pressure, and the dynamics of buckle propagation. Buckle propagation under tension, in pipe-in-pipe pipeline systems, and confined buckle propagation in tubulars such as grouted casing are examined in dedicated chapters. Three chapters deal with the performance of the most commonly used buckle arrestors under both quasi-static and dynamic buckle propagation. Each of these problems is studied through experiments, analyses, and large-scale numerical simulations. The results are used to provide empirical design equations and design guidelines on how to mitigate the effects of buckle propagation. Buckle propagation and arrest approached from both fundamental and applied points of view Provides data, empirical design formulae, and design guidelines Teaches how to analyze buckle propagation and mitigate its effects through experiment and modeling Based on the 40-year research and practice of the most eminent researcher in the subject

Offshore Pipelines covers the full scope of pipeline development from pipeline designing, installing, and testing to operating. It gathers the authors' experiences gained through years of designing, installing, testing, and operating submarine pipelines. The aim is to provide engineers and management personnel a guideline to achieve cost-effective management in their offshore and deepwater pipeline development and operations. The book is organized into three parts. Part I presents design practices used in developing submarine oil and gas pipelines and risers. Contents of this part include selection of pipe size, coating, and insulation. Part II provides guidelines for pipeline installations. It focuses on controlling bending stresses and pipe stability during laying pipelines. Part III deals with problems that occur during pipeline operations. Topics covered include pipeline testing and commissioning, flow assurance engineering, and pigging operations. This book is written primarily for new and experienced engineers and management personnel who work on oil and gas pipelines in offshore and deepwater. It can also be used as a reference for college students of undergraduate and graduate levels in Ocean Engineering, Mechanical Engineering, and Petroleum Engineering. * Pipeline design engineers will learn how to design low-cost pipelines allowing long-term operability and safety. * Pipeline operation engineers and management personnel will learn how to operate their pipeline systems in a cost effective manner. * Deepwater pipelining is a new technology developed in the past ten years and growing quickly.
