The origin and limitations of the Morison-O'Brien-Johnson-Schaff (MOJS) equation, the nature and decomposition of the time-dependent in-line force, the speculative generalizations of the MOJS equation to body shapes other than circular cylinders, to yawed cylinders, to wave-current combination, and to dynamic response of structures are discussed in detail. The background and the limitations of the existing data are reviewed and the data from sinusoidally-oscillating planar flow about smooth and rough circular cylinders are chosen to critically assess the MOJS equation. Six methods are examined to delineate the limitations of the MOJS equation and to devise a new force expression. The final method used (the Fourier analysis of the residues) led to the formulation of a three-term and a four-term MOJS equation. It is shown through numerous examples that the new MOJS equation reduces the residue significantly for both smooth and rough circular cylinders, particularly in the drag inertia dominated regime. Finally, the applicability of the new equation to the ocean conditions and the effect of spanwise coherence are discussed and numerous research projects are recommended for consideration. The suggestion is made that further improvement and understanding of the MOJS equation rest not only with carefully conducted laboratory investigations but also with additional ocean test designed to shed light on several complicating influences such as the spanwise coherence of vortices and vortex interactions.

Unique, cutting-edge material on structural dynamics and natural forces for offshore structures Using the latest advances in theory and practice, Dynamics of Offshore Structures, Second Edition is extensively revised to cover all aspects of the physical forces, structural modeling, and mathematical methods necessary to effectively analyze the dynamic behavior of offshore structures. Both closed-form solutions and the Mathematica(r) software package are used in many of the up-to-date example problems to compute the deterministic and stochastic structural responses for such offshore structures as buoys; moored ships; and fixed-bottom, cable-stayed, and gravity-type platforms. Throughout the book, consideration is given to the many assumptions involved in formulating a structural model and to the natural forces encountered in the offshore environment. These analyses focus on plane motions of elastic structures with linear and nonlinear restraints, as well as motions induced by the forces of currents, winds, earthquakes, and waves, including the latest theories and information on wave mechanics. Topics addressed include multidegree of freedom linear structures, continuous system analysis (including the motion of cables and pipelines), submerged pile design, structural modal damping, fluid-structure-soil interactions, and single degree of freedom structural models that, together with plane wave loading theories, lead to deterministic or time history predictions of structural responses. These analyses are extended to statistical descriptions of both wave loading and structural motion. Dynamics of Offshore Structures, Second Edition is a valuable text for students in civil and mechanical engineering programs and an indispensable resource for structural, geotechnical, and construction engineers working with offshore projects.

The subject of hydrodynamics applied to offshore structures is vast. The topics covered in this book aim to help the reader understand basic principles while at the same time giving the designer enough information for particular designs. Thus, results are given with derivations, and applications are discussed with the aid of examples, with an overview of the advantages and limitations of the method involved. This makes the book suitable as a text for undergraduate and graduate students specializing in offshore and ocean engineering.

In a unitary way, this monograph deals with a wide range of subjects related to the mechanics of sea waves. The book highlights recent theoretical results on the dynamics of random wind-generated waves, on long-term wave statistics, and on beach planform evolution. A fresh approach is given to more traditional concepts. For example, new evidence from a recent series of small-scale field experiments is used to introduce some crucial topics like wave forces. Also, the book gives some worked examples for the design of offshore or coastal structures. An exciting subject dealt with in the book is the quasi-deterministic mechanics of three-dimensional wave groups in sea storms, and the loads exerted by these wave groups on offshore structures. The text is intended for researchers and graduate students in ocean engineering, but may also be understood by undergraduates. The more complex concepts are explained with examples or more extensive case studies.
