Available in PDF, EPUB and Kindle. Book excerpt: The responses of offshore structures are significantly affected by steep nonlinear waves, currents and wind, leading to phenomena such as springing and ringing of TLPs, slow drift yaw motion of FPSOs and large oscillations of Spar platforms due to vortex shedding. Research has brought about significant progress in this field over the past few decades and introduced us to increasingly involved concepts and their diverse applicability. Thus, an in-depth understanding of steep nonlinear waves and their effects on the responses of offshore structures is essential for safe and effective designs.This book deals with analyses of nonlinear problems encountered in the design of offshore structures, as well as those that are of immediate practical interest to ocean engineers and designers. It presents conclusions drawn from recent research pertinent to nonlinear waves and their effects on the responses of offshore structures. Theories, observations and analyses of laboratory and field experiments are expounded such that the nonlinear effects can be clearly visualized.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the development of the two-dimensional time domain solver cBEM for modeling linear hydrodynamic problems is described. The approach was based on Potential Flow Theory and applied Boundary Integral Equations with that the governing Boundary Value Problem was solved and the interactions of body and surface gravity waves were modeled. The embedding of the High-Order Spectral procedure into the Boundary Element Method in the symmetric Galerkin formulation represents an innovative coupling method for the treatment of hydrodynamic problems. The explicit account of a surface discontinuity represented by the body in the free surface boundary domain, the strategy of incorporating the High-Order Spectral approach in the Boundary Element Method, and the development of suited desingularization techniques for kernel functions up to hypersingular order had been considered within this thesis. As higher-order basis functions had been used for the approximation of solution function space and geometry, the results of cBEM in terms of the boundary quantities, the potential and its normal derivative, were of good accuracy. cBEM can be accounted as the foundation of a highly efficient three-dimensional nonlinear Boundary Element Method solver with possible future application e.g. in the research fields of analyzing nonlinear body motion due to nonlinear wave excitation in numerical wave tanks and for the optimization of ship hull geometries in the early design phase. For offshore operations, the deterministic wave and motion prediction would help to increase safety and cBEM was designed to fit into a holistic approach containing wave inversion, nonlinear wave propagation, and motion prediction. The efficient evaluation of the mixed Boundary Value Problem with highly efficient methods would allow predictions over a period of time that meets industry expectations. The work is structured as follows. In the introduction, the scope of the work is highlighted and limitations and innovations are outlined. In the literature review presented thereafter, the Boundary Element Methods used in Marine Hydrodynamics are categorized into three main streams, and related research contributions are summarized. Based on this, the research gap is outlined and a global hypothesis defined. The research hypotheses structure and summarize the main concerns according to the global hypothesis and give the frame for the development of cBEM. In chapter two, the theory of Boundary Integral Equations and numerical tools accounted for in the Boundary Element Method approach are summarized. Furthermore, the Linear Wave Theory and the High-Order Spectral method as well as the basic problems of wave-body interaction are described. On the mathematical foundation and the introduction of the computational methods represented here, the steps for the development of the cBEM solver are presented in chapter three. After an overview of the steps, the Boundary Integral Equations for the different solvers are described. The direct formulation of cBEM is given and the methods accounted for in pre-, post-, and processing are introduced. It follows the verification of the approaches including the free surface solver fsBEM, the coupled solver cBEM, and the transient cBEM solver for the continuous and discontinuous surfaces. The validation section, chapter four, shows the application of cBEM for hydrodynamic problems. The submerged and free surface piercing geometries were considered and linear problems with a forced oscillating body, the free surface elevation over a submerged cylinder, and the diffraction of waves due to a body below were compared with literature references. The final discussion in the review of the research hypotheses follows and the conclusions are drawn. By identifying the status of the work described herein, future steps are pointed out. The extension of cBEM to a three-dimensional solver, equipped with efficient solving strategies and nonlinear extensions is outlined and future applications are given. Their potential is highlighted and the required developments are depicted.

This book was released on 2012-12-06 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Boundary Element Method (BEM) has become established as an effective tool for the solutions of problems in engineering science. The salient features of the BEM have been well documented in the open literature and therefore will not be elaborated here. The BEM research has progressed rapidly, especially in the past decade and continues to evolve worldwide. This Symposium was organized to provide an international forum for presentation of current research in BEM for linear and nonlinear problems in solid and fluid mechanics and related areas. To this end, papers on the following topics were included: rotary wing aerodynamics, unsteady aerodynamics, design and optimization, elasticity, elasto dynamics and elastoplasticity, fracture mechanics, acoustics, diffusion and wave motion, thermal analysis, mathematical aspects and boundary/finite element coupled methods. A special session was devoted to parallel/vector supercomputing with emphasis on mas sive parallelism. This Symposium was sponsored by United Technologies Research Center (UTRC) , NASA Langley Research Center, and the International Association of Boundary Ele ment Methods (lAB EM) . We thank the UTRC management for their permission to host this Symposium. In particular, we thank Dr. Arthur S. Kesten and Mr. Robert E. Olson for their encouragement and support.
