Hydrodynamic Interaction Of Waves With A Large Displacement Floating Body

This report describes the analytical method and numerical procedure for the calculation of the wave pressure distribution and resulting induced forces and moments acting on large displacement bodies in the sea. The added mass and damping coefficients for the structure oscillating in all six degrees of freedom is computed. Then, the hydrodynamic coefficients associated with both the wave/structure interaction and the oscillation of the structure are determined by use of a Green's function method using quadralateral elements of constant source strength which applies to large structures of rather general shape. The analysis is based on linear theory and viscous effects are neglected on the basis that the size of the structure is large in relation to the amplitude of the incident wave. Also, the equations of motion for a free-floating body are developed which yields the dynamic response of a floating body with linear mooring line forces. Finally, the computer program capable of carrying out the numerical calculations is outlined and the input/output is discussed in some detail. (Author).

This handbook is the definitive reference for the interdisciplinary field that is ocean engineering. It integrates the coverage of fundamental and applied material and encompasses a diverse spectrum of systems, concepts and operations in the maritime environment, as well as providing a comprehensive update on contemporary, leading-edge ocean technologies. Coverage includes an overview on the fundamentals of ocean science, ocean signals and instrumentation, coastal structures, developments in ocean energy technologies and ocean vehicles and automation. It aims at practitioners in a range of offshore industries and naval establishments as well as academic researchers and graduate students in ocean, coastal, offshore and marine engineering and naval architecture. The Springer Handbook of Ocean Engineering is organized in five parts: Part A: Fundamentals, Part B: Autonomous Ocean Vehicles, Subsystems and Control, Part C: Coastal Design, Part D: Offshore Technologies, Part E: Energy Conversion

Theoretical and Applied Mechanics covers the proceedings of the 16th International Congress of Theoretical and Applied Mechanics, held at the Technical University of Denmark, Lyngby, Denmark on August 19-25, 1984. The contributors consider the significant advances in the thriving field of mechanics. This book is composed of 21 chapters, and begins with an overview of space research contributions in understanding fluid media mechanics. This topic is followed by discussions on some aspects and fundamentals of mechanics, such as chaos, computer application, resonant phenomena, adiabaticity, and nonlinear acoustics. The following chapters explore the various applications of theoretical and applied mechanics, including in marine structures, oil recovery, and ice and snow mechanics. This book also deals with nonlinear wave motion, hydrodynamic systems, ocean wave spectra, and Helmholtz concept. The remaining chapters look into the issues of steady water bifurcation, concept of anisotropic soils, and flow visualization. This book is of great value to physicists and research workers who wish to expand their knowledge in mechanics.
