Book Description
PacWave, with its location in some of the most energetic waters in the nation and a buildout to support grid-connected devices, is poised to become a leader in field testing of wave energy converters (WECs) at high technology readiness levels. As part of the device deployment and testing protocols at PacWave, the client is responsible for providing all mooring system components, since there are currently no mooring system components specified for PacWave. NREL and PNNL have been tasked with conducting a preliminary analysis of permanent or temporary mooring systems at the PacWave South site. Previous work for this task included a global trade study of mooring systems used for WECs, and a site characterization of PacWave South. This current report will use the results of the previous studies to inform the design of various mooring systems to be installed at PacWave, which will allow cost analyses to be performed to compare the costs of acquisition of these mooring systems and the costs of mooring systems designed specifically for clients' devices.

Book Description
The Complete Book addresses anchoring systems, techniques, and permanent moorings for boats from 12 to 80 feet in length. It covers monohulls, multihulls, light displacement sailboats, cruisers, sportfishers, passagemakers, and workboats. In short, it is for all recreational and working boats in this size range. The book deals not only with anchor behavior, but also with the rode assembly, riding stoppers, and the human factors. What formerly was thought of as strength through size (heavy anchors and large rodes) has been refined to decrease weight, lighten loads on the boat, and reduce difficulty in handling. Utilizing a systems approach with respect to equipment and techniques and analytical methods for loads, Earl R. Hinz has made a number of contributions to the state of the art. Among them are bow anchor roller design, chain locker and navel pipe design, elastic anchoring techniques, tandem anchor systems design, and designs for permanent moorings. Sections on ground tackle selection, tandem anchoring techniques, anchoring in coral, and improving hurricane moorings have been revised. Most of these designs and techniques are clearly illustrated in the schematic drawings by Richard R. Rhodes. The latest information on electric windlass troubleshooting, new anchor designs, anchor test data, use of screw anchors for more secure moorings, design of moorings for coral seabeds, and anchoring jurisdictional conflicts makes this second edition a state-of-the-art source book for the boating world.

Book Description
This book provides a comprehensive guide for the analysis and design of anchor systems used for mooring offshore floating structures. Much of the experience is based on applications toward the offshore oil and gas industry, but the substantial potential for offshore renewable energy systems is addressed. The major types of anchors are described with respect to their basic design concept, advantages and limitations, appropriate framework for analysis, and observed performance. This book addresses all aspects of anchor behaviour related to anchor design including the installation performance, load capacity, deformation, and structural integrity of the anchor itself. Coverage is also provided of appurtenant components of anchor systems, in particular of anchor line/chain mechanics in the soil and water columns. Much of the material presented represents relatively new developments, including several new anchors which have been developed within the last decade, so the book will provide a useful compendium of information is largely scattered in journals and conference proceedings. This book is intended for engineers engaged in offshore geotechnics and marine engineers involved in mooring system and floating structure design. While the analytical methods presented in this text have a strong theoretical basis, the emphasis is on simplified computational formats accessible to design engineers.

Book Description
This report presents the development of offshore anchor data sets which are intended to be used to develop a database that allows preliminary selection and sizing of anchors for the conceptual design of floating offshore wind turbines (FOWTs). The study is part of a project entitled "Development of Mooring-Anchor Program in Public Domain for Coupling with Floater Program for FOWTs (Floating Offshore Wind Turbines)", under the direction of Dr. Moo-Hyun Kim at the Texas A & M University and with the sponsorship from the US Department of Energy (Contract No. DE-EE0005479, CFDA # 81.087 for DE-FOA-0000415, Topic Area 1.3: Subsurface Mooring and Anchoring Dynamics Models).

Book Description
It is now widely recognized that there is a need for long-term secure and suitable sustainable forms of energy. Renewable energy from the marine environment, in particular renewable energy from tidal currents, wave and wind, can help achieve a sustainable energy future. Our understanding of environmental impacts and suitable mitigation methods associated with extracting renewable energy from the marine environment is improving all the time and it is essential that we be able to distinguish between natural and anthropocentric drivers and impacts. An overview of current understanding of the environmental implications of marine renewable energy technology is provided.

Book Description
'As a sniper, I've killed more than a few Nazis. I have a passion for observing enemy behaviour. You watch a Nazi officer come out of a bunker, acting all high and mighty, ordering his soldiers every which way, and putting on an air of authority. The officer hasn't got the slightest idea that he only has seconds to live.' Vassili Zaitsev's account of the hell that was Stalingrad is moving and harrowing. This was a battle to the death - fighting street by street, brick by brick, living like rats in a desperate struggle to survive. Here, the rules of war were discarded and a psychological war was being waged. In this environment, the sniper was king - an unseen enemy who frayed the nerves of brutalised soldiers. Zaitsev volunteered to fight at Stalingrad in 1942. His superiors recognized quickly his talent, and made him a sniper. He adapted his hunting skills to the ruins of the city, watching his prey with nerves of steel. In his first 10 days, Zaitsev killed 40 Germans. He achieved at least 225 kills and the tactics he developed are still being studied. Zaitsev was used a symbol of Russian resistance against the Nazis. His exploits, including a famous 'duel' with a Nazi sniper, remain the stuff of legend. His account is absorbing to anyone interested in World War II and seeing how one person could survive in the most extreme of conditions.
