Stability of Offshore Risers Conveying Fluid

“Stability of offshore risers conveying fluid” concentrates on the influence of internal flow on stability of pipes conveying fluid. The book covers both (semi-) analytical and experimental work. The book starts with the explanation of the one-dimensional equation of motion, standard solution techniques and energy considerations of a pipe conveying fluid. In subsequent chapters, more complicated systems are dealt with, including theoretical models of submerged offshore risers conveying fluid. Small-scale experiments of a 5 meter long free-hanging pipe aspirating fluid are treated as well. Striking results of these experiments are compared with theoretical models.

The theoretical and experimental work, as presented in this book, is strongly linked to applications in the offshore industry. For example, new concepts of liquefying LNG offshore require large quantities of cooling water. The pumping of cold seawater takes place through a set of steel water-intake risers, whose top is attached to the vessel, whereas the lower end is free. Axial flow-induced fatigue damage of this kind of pipe systems can be analyzed with the theory as explained in this book.

This book shows the latest state of the art on stability of offshore risers conveying fluid. Parts of the book have been published recently in several international refereed journals.
