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.

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 viewProvides data, empirical design formulae, and design guidelinesTeaches how to analyze buckle propagation and mitigate its effects through experiment and modelingBased on the 40-year research and practice of the most eminent researcher in the subject

Pipelines, and more generally long tubular structures, are major oil and gas industry tools used in exploration, drilling, production, and transmission. This title addresses problems of buckling and collapse of long inelastic cylinders under various loads encountered in the offshore arena.
