The true story about a shipwreck discovery, exciting explorations, broken alliances, and returning a lost piece of Alaskan history. Since its sinking in 1860 while transporting a valuable cargo of ice, the Kad’yak ship had remained submerged underwater and faded in Alaska’s memory, covered by the legend of an experienced but perhaps rusty sailor and a broken promise to a saint. At the time the ship had been under command of the well-recognized Captain Illarion Arkhimandritov, who had sailed in Alaskan waters for years. It seemed a simple task when he was asked to placate superstitions and honor the late Father Herman, or Saint Herman, on his next visit to Kodiak Island. But Arkhimandritov failed to keep his promise, and shortly thereafter the Kad’yak met its demise in the very waters the captain should have been most familiar with—leaving just the mast above the water in the shape of the cross, right in front of the saint’s grave. Presumed gone or else destroyed, it wasn’t until 143 years later that the Kad’yak was found. In this riveting memoir, scientist Bradley Stevens tells all about the incredible discovery and recovery of the ship—deciphering the sea captain’s muddled journal, digging through libraries and other scientists’ notes, boating over and around the wreck site in circles. Through careful documentation, interviews, underwater photography, and historical research, Stevens recounts the process of finding the Kad’yak, as well as the tumultuous aftermath of bringing the legendary ship’s story to the public—from the formed collaborations to torn partnerships to the legal battles. An important part of Alaska’s history told from Stevens’s modern-day sea expedition, The Ship, the Saint, and the Sailor reveals one of the oldest known shipwreck sites in Alaska discovered and its continuing story today.

70 per cent of the planet is covered by water, and 90 per cent of global economic trade is transported by sea. The world's seas and oceans are big business. Based on gross marine product, the ocean can be considered the world's seventh-largest economy, with the total global value of the Blue Economy predicted to rise to $3 trillion by 2030. Grounded in detailed market research, and brought to life through over 250 meticulously researched case studies, Technology and the Blue Economy presents a compelling overview of an inspiring and innovative sector that includes offshore renewable energy, ports and harbours, shipping, maritime surveillance, cyber security, aquaculture and ocean conservation. It tackles questions like these: * With Earth observation satellites providing unprecedented levels of data about the ocean, can machine learning capabilities develop at pace to make sense of all this new information? * How can ships protect themselves when one shipping firm alone records 50,000 daily attempts to breach its cyber security systems? * With floating wind farms now pushing further out to sea to convert natural energy, what role do robots have in managing essential maintenance in these more remote environments? * When passenger ferries are already sailing themselves and self-docking in port without human intervention, are we entering an age where human error is eradicated? * With fish farming predicted to account for 62 per cent of all the seafood consumed globally by 2030, how can 3D imaging cameras and net-cleaning robots help to stop mass deaths of fish that can run into millions in a single incident? * In the age of smartphone ubiquity, how important a role might social media and citizen science play in ocean conservation? * With luxury cruise ships now marketing themselves as 'smart, connected cities', crunching passenger data in real-time, do they now provide the gold standard of customer experience within the tourist industry? * Is optical scanning technology the solution to countering slavery at sea, a real concern in the south-east Asian fishing industry? * Can satellite-enabled tracking and autonomous clean-up systems help to counter one of the greatest conservation issues of the day - the fight against ocean plastic pollution? Technology and the Blue Economy explores how innovators can develop the right business models to capitalize on growth opportunities, and analyses the critical success factors for emerging technologies.

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.

Offshore Risk Assessment was the first book to deal with quantified risk assessment (QRA) as applied specifically to offshore installations and operations. Risk assessment techniques have been used for more than three decades in the offshore oil and gas industry, and their use is set to expand increasingly as the industry moves into new areas and faces new challenges in older regions. This updated and expanded third edition has been informed by a major R&D program on offshore risk assessment in Norway and summarizes research from 2006 to the present day. Rooted with a thorough discussion of risk metrics and risk analysis methodology, subsequent chapters are devoted to analytical approaches to escalation, escape, evacuation and rescue analysis of safety and emergency systems. Separate chapters analyze the main hazards of offshore structures: fire, explosion, collision, and falling objects as well as structural and marine hazards. Risk mitigation and control are discussed, as well as an illustration of how the results from quantitative risk assessment studies should be presented. The third second edition has a stronger focus on the use of risk assessment techniques in the operation of offshore installations. Also decommissioning of installations is covered. Not only does Offshore Risk Assessment describe the state of the art of QRA, it also identifies weaknesses and areas that need further development. This new edition also illustrates applications or quantitative risk analysis methodology to offshore petroleum applications. A comprehensive reference for academics and students of marine/offshore risk assessment and management, the book should also be owned by professionals in the industry, contractors, suppliers, consultants and regulatory authorities.

High loads with high dynamics in severe conditions can only be driven by fluid power mechanisms. Motion Control is often used as a description in various engineering disciplines to refer to a technological solution that is able to control motion, e.g. the movement of at least one part relative to another. This volume describes how drives, sometimes very large, are designed and realised. The book gives a practical explanation of the way in which the different mechanisms described work. A distinction is made between rotating and linear drives. In the case of rotating drives, the choice for an electrical drive is becoming more and more prevalent. Linear drives remain important, because of the large forces and highly dynamic behaviour in the domain of hydraulic drive technology. Both these important technologies are extensively discussed in this book, together with design rules and the many installation requirements for applications in the offshore and dredging industry.

The purpose of this book is to examine the geospatial and temporal linkage between offshore supply vessels and oil and gas activity in the Outer Continental Shelf Gulf of Mexico, and to model OSV activity expected to result from future lease sales. Oil and gas operations occur throughout the world wherever commercial accumulations exist, but no quantitative assessment has ever been performed on the marine vessels that support offshore activity. The OCS Gulf of Mexico is the largest and most prolific offshore oil and gas basin in the world, and a large number of marine vessels are engaged in operations in the region, but tracking their activity is difficult and requires specialized data sources and the development of empirical models. The challenge of modeling arises from the complexity and size of the system, and the particular limitations governing stochastic difficult-to-observe networks. This book bridges the gap with the latest technological perspective and provides insight and computational methods to inform and better understand the offshore sector. Offshore Service Industry and Logistics Modeling in the Gulf of Mexico is presented in three parts.  In Part 1, background information on the life cycle stages of offshore development and activity is reviewed, along with a description of the service vessels and port infrastructure in the region.  In Part 2, OSV activity in the Gulf of Mexico is baselined using PortVision data to establish spatial and temporal characteristics of vessel activity. In Part 3, the analytic framework used to quantify the connection between OSVs, ports, and offshore activity is described, and activity expected to arise from the 2012-2017 OCS lease program is forecast. Providing an invaluable resource for academics and researchers, this book is also intended for government regulators, energy and environmental analysts, industry professionals, and others interested in this often-overlooked sector.

The mathematical description of the properties of a shell is much more elaborate than those of beam and plate structures. Therefore many engineers and architects are unacquainted with aspects of shell behaviour and design, and are not familiar with sufficiently reliable shell theories for the different shell types as derived in the middle of the 20th century. Rather than contributing to theory development, this university textbook focuses on architectural and civil engineering schools. Of course, practising professionals will profit from it as well. The book deals with thin elastic shells, in particular with cylindrical, conical and spherical types, and with elliptic and hyperbolic paraboloids. The focus is on roofs, chimneys, pressure vessels and storage tanks. Special attention is paid to edge bending disturbance zones, which is indispensable knowledge in FE meshing. A substantial part of the book results from research efforts in the mid 20th century at Delft University of Technology. As such, it is a valuable addition to the body of shell research literature of continuing importance. This work can be used for university courses. It also shows professionals how to perform manual calculations of the main force flow in shell structures, and provides guidance for structural engineers estimating stresses and deformations.

The historical importance and archaeological potential of deliberately discarded watercraft has not been a major feature of maritime archaeological enquiry. While research on the topic has appeared since the 1970s as books, chapters, and articles, most examples have been limited in focus and distribution, and in most cases disseminated as unpublished archaeological reports (i.e. the "gray literature".) So, too, has there been a lack of a single source representing the diversity of geographical, historic, thematic, and theoretical contexts that ships' graveyard sites and deliberately abandoned vessels represent. In contrast with much of the theoretical or case-specific literature on the theme of watercraft discard, this volume communicates to the reader the common heritage and global themes that ships' graveyard sites represent. It serves as a blueprint to illustrate how the remains of abandoned vessels in ships' graveyards are sites of considerable research value. Moreover, the case studies in this volume assist researchers in understanding the evolution of maritime technologies, economies, and societies. This volume is intended to expose research potential, create discussion, and reinforce the significance of a prevalent cultural resource that is often overlooked.

This book provides readers with alternative robust approaches to control design for an important class of systems characteristically associated with ocean-going vessels and structures. These systems, which include crane vessels, on-board cranes, radar gimbals and a conductivity temperature and depth winch, are modelled as manipulators with oscillating bases. One design approach is based on the H-infinity control framework exploiting an effective combination of PD control, an extended matrix polytope and a robust stability analysis method with a state-dependent coefficient form. The other is based on sliding-mode control using some novel nonlinear sliding surfaces. The model demonstrates how successful motion control can be achieved by suppressing base oscillations and in the presence of uncertainties. This is important not only for ocean engineering systems in which the problems addressed here originate but more generally as a benchmark platform for robust motion control with disturbance rejection. Researchers interested in the robust control of mechanical systems operating on unstable bases will find this monograph valuable. MATLAB (R) and Simulink (R) programs are available for download to make the methods described in the text easier to understand and to allow readers to experience practical procedures at first hand.

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.

By outlining a new design or the Kuroshio power plant, new approaches to turbine design, anchorage system planning, deep sea marine engineering and power plant operations and maintenance are explored and suggested. The impact on the local environment, particularly in the face of natural disasters, is also considered to provide a well rounded introduction to plan and build a 30MW pilot power plant. Following a literature review, the six chapters of this book propose a conceptual design by focusing on the plant's core technologies and establish the separate analysis logics for turbine design and the relay platforms. This is tempered against the ecological impact of both the construction and operation of the plant. These proposed technologies and plans can be further applied to power generation in other waters such as the Gulf Stream, the East Australian Current the Humboldt Current and the East Africa Coastal Current. Engineers, students and industry professionals are provided with a solid introduction to power plant technology as well as a design with specific real world applications
