The dynamic behavior of pipelines describes the time-varying continuous response of these structures under extreme effects, that are generated by the surrounding environment (waves and sea currents) and motions imposed by the host floating facility. This book describes all known impacts that affect the behavior and operation of a pipeline conveying an inner flow for underwater applications. "Known Impacts" are those phenomena that are considered important according to practice and experience. Underwater pipelines are typical, unique structures that are attached to unique floating facilities....
