Book SynopsisUnmanned marine vehicles (UMVs) is a collective term commonly used to describe autonomous underwater vehicles, remotely operated vehicles, semi-submersibles, and unmanned surface craft. UMVs are heavily used in the military, civilian, and scientific communities for undertaking designated missions whilst either operating autonomously and/or in co-operation with other types of vehicles. Advanced marine vehicles are increasing their capabilities and the degree of autonomy more and more in order to perform more sophisticated maritime missions. Remotely operated vehicles are no longer cost-effective since they are limited by economic support costs, and the presence and skills of the human operator. Alternatively, autonomous surface and underwater vehicles have the potential to operate with greatly reduced overhead costs and level of operator intervention. An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. UAVs are a component of an unmanned aircraft system (UAS); these include a UAV, a ground-based controller, and a system of communications between the two. Compared to manned aircraft, UAVs were originally used for missions too "dull, dirty or dangerous" for humans. While they originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications such as policing, peacekeeping and surveillance, product deliveries, aerial photography, agriculture, smuggling, and drone racing. Civilian UAVs now vastly outnumber military UAVs, with estimates of over a million sold by 2015, so they can be seen as an early commercial application of Autonomous Things, to be followed by the autonomous car and home robots. Nowadays, UMVs and UAVs are playing an increasingly important role in both controlling community and engineering applications. For example, UMVs and UAVs provide more efficient ways to execute various challenging tasks. However, these systems are usually featured with dynamics coupling, actuator saturation, underactuated structure, time-varying disturbance, etc., thereby resulting in great challenges and difficulties in system analysis and controller design. Recently, by employing intelligent approaches, advanced control methodologies for unmanned systems have been rapidly developed. Note that the dynamic environment is usually changing and the unmanned systems must adapt themselves accordingly. In this context, on one hand, more efforts should be focused on the methodology of the learning system. For example, fast adaptation and self-organizing capability are essentially required. On the other hand, advanced analysis tools should be deployed to enhance the control performance. Towards this end, human-like intelligence should be integrated tightly with nonlinear design for complex control tasks of autonomous systems. The main objective of this edited book is to address various challenges and issues pertinent to the intelligent control of UMVs and UAVs. (Nova)

Book SynopsisThis modern classic of small boat literature details the history of the Nordic Folkboat--a class that enjoys remarkable popularity in some of the world's most beautiful and challenging sailing waters. A clinker design that sails equally fast and well whether it is made from wood or fiberglass, the Nordic Folkboat has been around for 60 years. It has stood the test of time as its minimalism, robustness and sea kindliness have proved resistant to radical design modifications. Loibner guides us through all the layers of the Folkboat community, from those who sail competitively in the many Folkboat regattas worldwide, to the devoted following of recreational sailors who appreciate the sturdiness of the design when out cruising with family and friends, to what he refers to as the "Lunatic Fringe." Any reader who has spent a thrilling afternoon on the dancing prow of a small boat will appreciate the insights and journey of The Folkboat Story.Trade ReviewNow in paperback, this is a modern classic detailing the history of the Nordic Folkboat. Designed during the early years of World War II, the 25-foot Folkboat has gone from cult to classic, maintaining a devoted following. Boats of all ages are still being sailed today. The Folkboat has also inspired spin-offs, such as the Contessa 26 which was sailed around the world by Tania Aebi who wrote the Foreword for this latest edition. * Latitudes & Attitudes *Loibner writes that the Spartan 25-foot Folkboat epitomizes the enduring 'less is more' philosophy, which is, perhaps, an important metaphor for these times. * Sailing *Designed by committee in Scandinavia in the 1940s, the Nordic Folkboat was intended to bring yacht racing to the masses; Loibner explores the vitalility and popularity of the design. * Wooden Boat *Loibner takes us across the world in easy strides--from the Scandinavian base to the San Francisco enclave; from racing to cruising and with a charming chapter he calls the Lunatic Fringe. * Classic Boat *Table of ContentsAcknowledgments Foreword by Tania Aebi Prologue Chapter 1: A Design by Committee Chapter 2: Tord Sunden: Designer or Draftsman?

Book SynopsisIn General Naval Tactics, Naval War College professor and renowned tactical expert Milan Vego describes and explains those aspects of naval tactics most closely related to the human factor. Specifically, he explains in some detail the objectives and methods/elements of tactical employment of naval forces, command and control, combat support, tactical design, decision-making and planning/execution, leadership, doctrine, and training. Vego derives certain commonalities of naval tactics that occurred in recent and distant wars at sea. Many parts of his theoretical constructs are based on works of a number of well-known and influential naval theoreticians such as Admirals Alfred T. Mahan, Bradley A. Fiske, Raoul Castex, and Ren?® Daveluy and influential naval theoreticians. Whenever possible, the author illustrates each aspect of theory by carefully selected examples from naval history--making the theory more understandable and interesting. Vego aims to present theory that is general in nature and therefore, more durable in its validity. The more general the theory, the greater the possibility of accommodating changes based on new interpretations of past events and as a result of gaining fresh insight from the lessons learned.Trade ReviewIn a meticulous, detailed and comprehensive way, Milan Vego provides us with a definitive guide to Naval Tactics which will surely become a standard text on the subject. It also offers a much-needed corrective to the modern tendency to overestimate the extent to which technology dominates the tactical scene." —Geoffrey Till, Emeritus Professor of Maritime Studies, King's College, London"In this original and innovative work, Milan Vego demonstrates convincingly that despite changes in technology and capability over the centuries, an awareness of theory, a broad and deep knowledge of historical precedent, and realistic training can provide naval practitioners with the attributes needed to think tactically and succeed in combat." —Craig L. Symonds, author of World War II at Sea"In General Naval Tactics Dr. Vego provides a comprehensive tactical doctrine from tactical design to training, interwove with supporting instances from past naval battles. Masterfully written, this book is a cornerstone for every naval officer's professional library." —Capt. Jeffrey E. Kline, USN (Ret.) and Professor of Practice Military Operations Research, Naval Postgraduate School

Book SynopsisIn this work, ship hydrodynamics during inland waterway transport and ship manoeuvring are investigated using CFD (Computational Fluid Dynamics) based on OpenFoam. Validation and verification studies are carried out for the mesh convergence, time step convergence, sensitivity to turbulence models and dynamic mesh techniques. A quaternion-based 6DoF motion solver is implemented for the trim and sinkage predictions. Environmental effects on several inland vessels (convoy 1, convoy 2, tanker) are studied using the validated numerical models. Three important aspects, the confinement effect of the waterway, head-on encounter, and ship-bridge pile interaction are simulated. The testing conditions cover a wide range, including various channel dimensions, water depths, ship draughts and speeds. The ship resistance, wave pattern, Kelvin angle and wave elevation at specific positions are investigated as functions of these parameters. Ship manoeuvring is investigated using virtual captive model tests based on the MMG (Mathematical Maneuvering Group) model. An actuator disk is implemented to replace the real propeller. Open water test, rudder force test, OTT (Oblique Towing Tank test) and CMT (Circular Motion Test) of a KVLCC2 model are carried out to obtain the hydrodynamic coefficients of the propeller, rudder and ship hull. Using the obtained coefficients, system-based manoeuvring simulations are carried out and validated using the free running test data. These studies reproduce real ship tests and thus prove the validity of our numerical models. As a result, the numerical solver is promising in ship hydrodynamics and marine engineering simulations.

Book SynopsisWorld trade was revolutionized in the 19th Century when ships went from sail to steam. When did the first steamship cross the Atlantic? Who built it? Where? Several ships have claimed that title, but the true answer lies in Canada where steamboats were plying the rivers and lakes since the 19th century. The Paddle Steamer Royal William, built at the Campbell and Black shipyard in the Port of Quebec, steamed across the Atlantic from Pictou, Nova Scotia, to Portsmouth, England in 1833. That was the first transatlantic crossing under steam. Ships from the US and Holland have challenged her right to the title. This book shows that the PS Royal William's claim is valid.

Book SynopsisLocalization for underwater robots remains a challenging issue. Typical sensors, such as Global Navigation Satellite System (GNSS) receivers, cannot be used under the surface and other inertial systems suffer from a strong integration drift. On top of that, the seabed is generally uniform and unstructured, making it difficult to apply Simultaneous Localization and Mapping (SLAM) methods to perform localization. Reliable Robot Localization presents an innovative new method which can be characterized as a raw-data SLAM approach. It differs from extant methods by considering time as a standard variable to be estimated, thus raising new opportunities for state estimation, so far underexploited. However, such temporal resolution is not straightforward and requires a set of theoretical tools in order to achieve the main purpose of localization. This book not only presents original contributions to the field of mobile robotics, it also offers new perspectives on constraint programming and set-membership approaches. It provides a reliable contractor programming framework in order to build solvers for dynamical systems. This set of tools is illustrated throughout this book with realistic robotic applications.Table of ContentsPreface xi Notations xiii Abbreviations xvii Introduction xix Part 1.

Book SynopsisA new edition of this established text has been expanded and updated, treating this important field in a holistic manner. The structure of the previous book has been retained, but enhanced with new text and illustrations, and more numerical problems with a wider scope. Readers will find much on the background to the industry and details of such centrally important operations as refining, heat exchange, cracking, polymerisation and hydrogenation. There is a chapter on offshore matters, which includes some incidents that occurred since the first edition. National and international standards are considered as these relate to such things as site layout. The coverage of the fire and explosion behaviour of hydrocarbons has been extended, in particular in relation to flash points. The topic of leaked gas detection has been introduced, and there is considerable extension of the coverage of static electricity hazards. There is more on liquefied natural gas (LNG), including details of processes for its regasification. Natural gas condensate features, having grown considerably in importance since the first edition.Re-refining of crude oil products that have previously been used as lubricants or as hydraulic fluids has also experienced growth, and this too has its place in the book from the perspective of safety. Tight gas and coal bed methane feature, as does the controversial matter of hydraulic fracture to obtain them. The chemical processing chapter has been extended to include hydrocracking, hydrodesulphurisation and hydrodenitrogenation. The COMAH (Control of Major Accident Hazards) regulations are covered and sign conventions for hazards are explained with illustrations.Trade ReviewReviews of the first edition: 'A particularly useful feature for the practitioner and student is the inclusion within the text of worked examples... ...is particularly useful through its provision of a well grounded numerical approach to many of the detailed problems arising within process safety. ...provides much useful information on operational practice, which is not often found in such texts, as well as a valuable range of supporting case studies. ...should be relevant to both undergraduates and postgraduates, as well as those in industry approaching the subject for the first time'. Energy '...covers virtually all aspects of hydrocarbon safety...'

Book SynopsisBased upon the author's wide experience in a broad range of projects, this invaluable book sets the scene and places rock installation in the context of the offshore industry today. This is an industry where health, safety and environmental considerations are factored in to a project with the same level of professionalism as regulatory compliance and good design. Full information is provided about planning, preparation, execution and reporting of a rock installation project. Brief but key information is provided about rock types, the nature of the seabed and the relationship between the quarry and the receiving vessel, which together form a system of turning a terrestrial geological formation into a rock berm offshore. Rock installation vessels, their characteristics, equipment and capabilities are examined in outline. This book is based upon personal experience offshore in a series of rock installation projects over the last 16 years. It covers the oil and gas sector, coastal engineering, power and telecom cable projects and draws on practice in the UK, Norwegian and Danish Exclusive Economic Zones where much rock installation takes place. The range in scale is significant, from large oil field development projects to those of a much more specialised nature such as the preparation of sites from which a jackup rig can safely operate. The marine environment is examined in some detail. The author believes that all personnel working in the offshore industry, whether at sea or in onshore positions, need to understand the harsh but majestic, hostile and often unforgiving marine environment. With a number of new operators developing both end of life and new fields, knowledge concerning SRI has been diluted or even lost. This book is a useful enabler for project staff and new client representatives offshore to have a productive rock installation experience from the initial discussions with a contractor to the final results and verification.Table of ContentsPreface; Foreword; Abbreviations; Glossary; Introduction; Health, safety and environmental issues; Quality control and quality assurance; Brief summary of law at sea; A short history of subsea rock installation (SRI); Purpose and uses for SRI; Industry requirements of SRI; The contract; Rock types and uses; Quarries and quarry operations; Rock installation vessels; Operational considerations; The final product; Appendices; Index
