Performance Technology And Application Of High Performance Marine Vessels Volume One

There has been tremendous growth in the development of advanced marine vehicles over the last few decades and many of these developments have been presented at the International High Performance Marine Vehicles Conference held annually since 1997 in Shanghai, China. This comprehensive first volume covers high speed monohulls, multihulls, hydrofoil craft, air cavity craft and wing-in-ground effect craft. The papers cover a wide variety of hullforms, including deep-V hulls, stepped hulls, axe-bow hullforms, trimarans and pentamarans, foil assisted catamarans and air-lubrication craft. All aspects of design, including resistance, powering, seakeeping and maneuvering performance of these vessels, are covered through theoretical, experimental and numerical investigations.

High Performance Marine Vessels (HPMVs) range from the Fast Ferries to the latest high speed Navy Craft, including competition power boats and hydroplanes, hydrofoils, hovercraft, catamarans and other multi-hull craft. High Performance Marine Vessels covers the main concepts of HPMVs and discusses historical background, design features, services that have been successful and not so successful, and some sample data of the range of HPMVs to date. Included is a comparison of all HPMVs craft and the differences between them and descriptions of performance (hydrodynamics and aerodynamics). Readers will find a comprehensive overview of the design, development and building of HPMVs.

This is a comprehensive two-volume set of books devoted to the hydrodynamics of high-performance marine vessels. These vessels may also be generally referred to as high-speed or advanced marine craft. Types of craft addressed include monohulls, catamarans, trimarans and other multihull vessels, air-cushion vehicles, surface-effect ships and planing craft.The hydrodynamic aspects dealt with are the steady-state resistance, wave generation, sinkage and trim, unsteady effects and motions in waves. Separate chapters are devoted to viscous resistance, transom sterns and the behavior of skirts for air-cushion vehicles and seals for surface-effect ships. Effects of the finite depth of the water and the possible lateral restriction on the width of the waterway feature prominently in the books. In each case, the presentation includes a full analytical development of the theory accompanied by a comparison of the theoretical predictions with extensive experimental data.In the two volumes there is a total of 888 full-color Letter-size pages. The text is accompanied by 433 photographs of ships and ship models, 1155 graphs, 1295 equations and 1249 references.The work represents the author's research, consulting and professional experience in both universities and research centers spanning a period of over fifty years. The books are targeted at university-level students and specialized industry engineers in the field of naval architecture and associated areas.

High speed catamaran and multihull high speed marine vessel have become very popular in the last two decades. The catamaran has become the vessel of choice for the majority of high speed ferry operators worldwide. There have been significant advances in structural materials, and structural design has been combined with higher power density and fuel efficient engines to deliver ferries of increasing size. The multihull has proven itself to be a suitable configuration for active power projection across oceans as well as for coastal patrol and protection, operating at high speedd for insertion or retrieval with a low energy capability. At present there is no easily accessible material covering the combination of hydrodynamics, aerodynamics, and design issues including structures, powering and propulsion for these vehicles. Coverage in High Speed Catamarans and Multihulls includes an introduction to the history, evolution, and development of catamarans, followed by a theoretical calculation of wave resistance in shallow and deep water, as well as the drag components of the multihull. A discussion of vessel concept design describing design characteristics, empirical regression for determination of principal dimensions in preliminary design, general arrangement, and methods is also included. The book concludes with a discussion of experimental future vehicles currently in development including the small waterplane twin hull vessels, wave piercing catamarans, planing catamarans, tunnel planing catamarans and other multihull vessels.

Although the primary audience for this book is undergraduate university students studying naval architecture and marine engineering, the content will certainly be of interest to most designers working with high-speed craft. Author Donald L Blount says, "My intent has been to share the technical information, decision criteria, rules of thumb, and the opinionated experiences which have helped me in making choices for developing marine craft intended to operate beyond displacement speeds." According to Blount, Chapter One is a reprise of his article "Original Speed," (Professional BoatBuilder magazine, June/July 2008) followed by nine chapters of "science, my skewed views of science, a few things I don't understand, definitions of things on which no two naval architects will agree, design criteria which have been my friend, and guidance on design procedures embracing technology." This book also includes numerous graphs, charts, tables, and formulas to clarify the material in the text. He encourages you to personalize your copy with your own notes to make it even more valuable as a reference source and has included ample space for adding comments. ABOUT THE AUTHOR: Donald L Blount is the founder of Donald L. Blount and Associates, Inc. (Chesapeake, Virginia). During his 50-plus year career, he has designed numerous noteworthy vessels including the 67.7 m (222 ft) Destriero, which holds the non-refueled Atlantic crossing record, set in 1992 with an average speed of 53.1 knots earning the coveted Blue Ribband shown here. Registered as a professional engineer in two states, Blount is a fellow of both SNAME and RINA. He has served as Head of the Department of the U.S. Navy's Combatant Craft Engineering Department and also was employed at the David Taylor Model Basin. He has co-authored more than 50 papers and articles.

This set of two volumes comprises the collection of the papers presented at the 5th International Conference on Maritime Technology and Engineering (MARTECH 2020) that was held in Lisbon, Portugal, from 16 to 19 November 2020. The Conference has evolved from the series of biennial national conferences in Portugal, which have become an international event, and which reflect the internationalization of the maritime sector and its activities. MARTECH 2020 is the fifth of this new series of biennial conferences. The set comprises 180 contributions that were reviewed by an International Scientific Committee. Volume 1 is dedicated to maritime transportation, ports and maritime traffic, as well as maritime safety and reliability. It further comprises sections dedicated to ship design, cruise ship design, and to the structural aspects of ship design, such as ultimate strength and composites, subsea structures as pipelines, and to ship building and ship repair.

Air Lubrication and Air Cavity Technology is a major development that has emerged in recent years as a means to reduce resistance and powering for many types of ships, and an efficient design for high speed marine vessels. This book introduces the mechanisms for boundary layer drag reduction and concepts studied in early research work. Air bubble and sheet lubrication for displacement vessels is outlined and the key projects introduced. Generation of low volume flow air cavities under the hull of displacement, semi displacement and planing vessels are introduced together with theoretical and empirical analysis and design methods. Resistance reduction, power reduction and fuel efficiency are covered for both displacement and high speed vessels. Air layer and air cavity effects on vessel static and dynamic stability are covered, linked to regulatory requirements such as IMO. Seaway motions and reduced impact load of high speed craft in waves are discussed including model test results. Integration of propulsion systems for optimum powering is summarized. A design proposal for a wave piercing air cavity craft is included in an appendix. A comprehensive listing of document resources and internet locations is provided for further research.
