This book provides a comprehensive overview of design methods, addressing system layout determination, wall thickness design, route selection, fabrication, installation and tie-in methods, and pre-commissioning methodologies. The scope includes deep water as well as shallow water installations, with the main emphasis on hydrocarbons (oil, gas or multi-phase) though other media such as water, slurry and carbon dioxide are also covered. It concentrates on pressure containment steel pipelines, including flexible lines.The book is aimed primarily at engineers new to the subject of marine pipelines, but will also supply background reading for students of offshore engineering and for experienced pipeline engineers needing a quick reference.
