Proceedings of the IUTAM Symposium on Fluid- Structure Interaction in Ocean Engineering, held in Hamburg, July 23-26, 2007. The study of gravity driven water waves interacting with fixed or freely floating objects is an active and important field of research in ocean engineering. The accurate prediction of large amplitude ship motions or of marine structures in severe seas is still a delicate problem in the field of fluid-structure interaction. While three-dimensional panel methods have reached the state of maturity in linear sea-keeping analysis, the original problem, governed by strongly nonlinear boundary conditions, is far from being solved efficiently. The principal nonlinearities are associated with the variable wetted surface of the ship hull or the floating body and with the nonlinear hydrodynamic conditions on the free surface. Moreover, marine structures often must be modelled as multibody systems rather than a single body. This causes additional problems due to wave slamming on floating and fixed structures. Furthermore, problems such as coupled structural behavior of submerged or floating systems as well as various wind effects have to be considered for the proper design of offshore systems. This book collects contributions from leading scientists working on the following topics: Ocean waves, probabilistic models of sea waves, fluid-loading on structures including pipes, cables, drill-strings etc., behavior of floating systems, stability and capsizing of ships, coupled structural behavior, sloshing in tanks, CFD validation and verification.

Two previous NATO Advanced Study Institutes (ASI) on berthing and mooring of ships have been held; the first in Lisboa, Portugal in 1965, and the second at Wallingford, England in 1973. These ASls have contributed significantly to the under standing and development of fenders and mooring, as have works by Oil Companies International Marine Forum (1978) and PIANC (1984). Developments in ship sizes and building of new specialized terminals at very exposed locations have necessitated further advances in the combined mooring and fendering technology. Exploration and exploitation of the continental shelves have also brought about new and challenging problems, developments and solutions. Offshore activities and developments have in fluenced and improved knowledge about both ships and other floating structures which are berthed and/or moored under various environmental conditions. The scope of this ASI was to present recent advances in berth ing and mooring of ships and mooring of floating offshore structures, focusing on models and tools available with a view towards safety and reduction of frequencies and consequences of accidents."

Newly updated and translated into English for the first time, this standalone handbook perfectly combines background and theory with real-world experiments. All key topics are covered, including environmental conditions, wave theories, hydrostatics, and wave and current loads, with emphasis on nonlinear wave body interaction. Focus is given to model testing, an important component in the design of offshore structures. Recent results on the hydrodynamics of perforated structures, moonpool and gap resonance, and third-order interaction effects, have been added to this updated version. Based on practical experience from multiple industry collaborations, combined with lectures that have been honed and improved over more than 30 years, the pedagogical, real-world approach in this book make it an ideal companion for graduate students and researchers as well as ocean engineers.

HYDRODYNAMIC PROPULSION AND ITS OPTIMIZATION ANALYTIC THEORY Hydrodynamic propulsion has been of major interest ever since craft took to the water. In the course of time, many attempts have been made to invent, develop, or to improve hydrodynamic propulsion devices. Remarkable achievements in this field were made essentially by experienced individuals, who were in need of reliable propulsion units such as paddle wheels, sculling devices, screw propellers, and of course, sails. The problem of minimizing the amount of input energy for a prescribed effective output was first investigated seriously at the beginning of this century. In 1919, BETZ presented a paper on air-screw propellers with minimum consumption of energy which could be applied to ship-screw propellers also. Next, attempts were made to optimize hydrodynamic propulsion units. Ensuing investigations concerned the optimization of the hydrodynamic system: ship-propeller. The first simple theory of ship propulsion which was presented considered more or less only thrust augmentation, wake processing and modification of propeller characteristics when operating behind the ships hull. This theory has been little improved meanwhile and is still useful, particularly with regard to practical ship design and for evaluating results of ship model tests. However, this theory is not adequate for optimization procedures necessary for high-technology propulsion, particularly for ship propellers utilizing propulsion improving devices such as tip end plates or tip fins at the propeller blades, spoilers in front of the propeller, asymmetrical stern etc.

It is a pleasure to introduce to the reader this new Marine Painting Manual. The previous edition, entitled Ship Painting Manual, was published in 1975. Since then a number of new technological developments have taken place. Also, standards with regard to safety, health and the environment have become more severe. These changes called for a thoroughly revised and updated Marine Painting Manual. I believe that the editor should be congratulated on having completed this task in such a commendable way. I hope that this new volume will find as enthusiastic a response among those concerned with maritime affairs as its predecessor did some fifteen years ago. Dr. Jan Raat Director Netherlands Foundation for the Co-ordination of Maritime Research INTRODUCTION The "Marine Painting Manual" sets out to provide clear guidelines for the effective protection of marine structures, ocean-going vessels and offshore platforms. Painting is a high cost procedure and is a crucial factor in determining the life and subsequent maintenance of steel structures in the marine environment. The book is a follow-up to the "Ship Painting Manual" published in 1975. It has been completely revised, partly rewritten and an additional chapter on offshore structures included. The present volume contains detailed and up-to-date information on all aspects of the preparation and painting for the protection of marine structures. The following chapters are included: 1. The protection of different parts of ships under construction. 2. The protection of different parts of offshore structures under construction. 3. Surface preparation.

The Channel Tunnel is a huge construction project, employing over 14,000 people at peak, and costing over <156>11 billion of private money. It has succeeded in spite of great financial, political and techncial difficulties, and a fundamentally flawed contract. This book tells the story of the project, based on the coverage in Construction News and with commentary taken from recent interviews with key project sources.

engineers into a single volume whilst concentrating on two important research control design problems: autopilots with rudder-roll stabilization and fin and combined rudder-fin stabilization. He has been guided by some of the leading marine control academics, in particular Mogens Blanke and Thor Fossen; indeed Chapters 3 and 4 on kinematics and kinetics of ship motion are jointly authored with Professor Fossen. There are some 240 cited references - an invaluable resource for interested readers. The volume is likely to appeal to a wide range of readers who will each be able to extract something different from the various parts of the monograph. Part I has some four chapters on the modelling fundamentals including kinematics, dynamics and actuators. Part II is a very useful survey of the ship roll stabilization problem and how ship roll performance is measured and assessed. This clearly motivates the human necessity for roll-reduction and roll stabilization. Parts III and IV move on to the control systems aspects of the various stabilization designs. Valuable material here includes a study of system performance limitations as caused by the presence of non-minimum phase characteristics and actuator saturation. Chapter 10 has an interesting historical review of these marine control problems stretching back some thirty-years into the 1970s.

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 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.

1. 1 Introduction As offshore oil production moves into deeper water, compliant structural systems are becoming increasingly important. Examples of this type of structure are tension leg platfonns (TLP's), guyed tower platfonns, compliant tower platfonns, and floating production systems. The common feature of these systems, which distinguishes them from conventional jacket platfonns, is that dynamic amplification is minimized by designing the surge and sway natural frequencies to be lower than the predominant frequencies of the wave spectrum. Conventional jacket platfonns, on the other hand, are designed to have high stiffness so that the natural frequencies are higher than the wave frequencies. At deeper water depths, however, it becomes uneconomical to build a platfonn with high enough stiffness. Thus, the switch is made to the other side of the wave spectrum. The low natural frequency of a compliant platfonn is achieved by designing systems which inherently have low stiffness. Consequently, the maximum horizontal excursions of these systems can be quite large. The low natural frequency characteristic of compliant systems creates new analytical challenges for engineers. This is because geometric stiffness and hydrodynamic force nonlinearities can cause significant resonance responses in the surge and sway modes, even though the natural frequencies of these modes are outside the wave spectrum frequencies. High frequency resonance responses in other modes, such as the pitch mode of a TLP, are also possible.

Essays explore the world of Michael of Rhodes, examining the historical context, the discovery of his manuscript, and Michael's knowledge of mathematics, shipbuilding, navigation, and other topics. In the fifteenth century, a Venetian mariner, Michael of Rhodes, wrote and illustrated a text describing his experiences in the Venetian merchant and military fleets. He included a treatise on commercial mathematics and treatments of contemporary shipbuilding practices, navigation, calendrical systems, and astrological ideas. This manuscript, "lost," or at least in unknown hands for over 400 years, has never been published or translated in its entirety until now. In volume 3, nine experts, including the editors, discuss the manuscript, its historical context, and its scholarly importance. Their essays examine the Venetian maritime world of the fifteenth century, Michael's life, the discovery of the manuscript, the mathematics in the book, the use of illustration, the navigational directions, Michael's knowledge of shipbuilding in the Venetian context, and the manuscript's extensive calendrical material.

New Tools, Old Tasks explores how Integrated Operations (IO) will influence the safety of offshore drilling operations. The book is based on several years of practical experience combined with a research study on the safety of IO within the drilling domain. The overall objective of the book is to explore how safety can be understood in the change process of Integrated Operations, and to provide recommendations for how IO may be developed and implemented in a way that will benefit both safety and efficiency of the operations. A crucial thread throughout the book is that the understanding of normal work processes is key to understanding the conditions for safe operations. This is reflected in the book's structure and content; the nature of normal drilling operations is the focus, including how technologies and work processes are aligned to meet the dominating challenges of the industry (these challenges need not be directly linked to safety/risk). It is argued that the influence of IO on the safety of drilling operations depends more on how IO relates to the existing fundamental challenges of drilling operations than on the design and properties of the different IO technologies and work processes as such.
