Offshore Wind is the first-ever roadmap to successful offshore wind installation. It provides a ready reference for wind project managers, teaching them how to deal with complications on-site, as well as for financers, who can utilize the text as an easy guide to asking the pivotal questions of petitioning wind project developers. These developers' planning stages will be improved by the book's expert advice on how to avoid wasting money by scoping out and mitigating potential problems up-front. Wind turbine manufacturers will benefit from insights into design optimization to support cheaper installation and hauling, thereby incurring lower project costs, and helping developers establish a quicker route to profitability. The book sheds light not just on how to solve a particular installation difficulty, but delves into why the problem may best be solved in that way. Enables all stakeholders to realize cheaper, faster, and safer offshore wind projects Explains the different approaches to executing on- and offshore projects, highlighting the economic impacts of the various financial and operational choices Provides practical, proven advice on how tough challenges can be overcome, using real-life examples from the author’s experiences to illustrate key issues

"This work presents the results of model tests and numerical simulations of shallow foundations subjected to cyclic loads typical of offshore loadings. Small-scale model tests on a shallow foundation, subjected alternately to cyclic loads with large and small amplitudes, have shown that the accumulated rotations due to large amplitude loads reduce during later phases with smaller amplitudes. Numerical simulations have revealed that this behaviour of cyclically loaded shallow foundations is quantitatively influenced by the load amplitude and direction, and number of load cycles. This work concludes with a proposal for foundation geometries that efficiently resist offshore cyclic loads."--Page 4 of cover.

Intermediate foundations are used as anchors for floating platforms and ancillary structures, foundations for steel jackets, and to support seafloor equipment and offshore wind turbines. When installed by suction, they are an economical alternative to piling, and also may be completely removed. They are usually circular in plan and are essentially rigid when laterally loaded. Length to diameter embedment ratios, L/D, generally vary between 0.5 and 10, spanning the gap between shallow and deep foundations, although these are indicative boundaries and the response, rather than the embedment ratio, defines an intermediate foundation. The first chapters introduce foundation types; compare shallow, intermediate and deep foundation models and design; define unique design issues that make intermediate foundations distinct from shallow and deep foundations, as well as list their hazards that mainly occur during installation. Later chapters cover installation, in-place resistance and in-place response, and miscellaneous design considerations. There is no general agreement as to which design methods/models are appropriate, so models should only be as accurate as the data. Therefore, several reasonably accurate models are provided together with comprehensive discussion and advice. Example calculations and over 200 references are also included. This is the first book dedicated to the geotechnical design of intermediate foundations, and it will appeal to professional engineers specialising in the offshore industry.

Offshore wind energy is one of the primary renewable sources of energy. The ongoing development of the capacity and distance to shore of offshore wind turbines (OWTs) lead to more severe loading conditions. The substructures for OWTs are required to be capable of withstanding the combined loads with vertical loads from the weight of upper structures, and relatively high lateral loads and resultant moments induced by waves, winds, ice and currents. Two types of innovative foundations: the suction bucket foundation and monopile-friction wheel foundation are investigated in this dissertation via centrifuge modellings and finite element (FE) analyses.Suction bucket foundations are a promising foundation option for offshore wind turbines. To assess the lateral-moment loading capacity of bucket foundations, a group of 3-D finite element (FE) simulations with different bucket dimensions in sand and clay is carried out based on the centrifuge model tests. The numerical methods are validated by comparisons with the results of centrifuge tests, and assessed by sensitivity analyses regarding the influences of soil properties and soil-foundation interface parameters. The interaction between the bucket and surrounding soil is illustrated in order to demonstrate the bearing behavior and failure mechanism of the bucket foundation. It is shown that in the ultimate state, the maximum passive earth pressure acting on the external skirt in the loading direction is approximately 4 times larger than that on the internal skirt. Furthermore, parametric studies on the L/D ratios (L is the skirt length and D is the bucket diameter) and loading eccentricity are conducted and discussed. Consequently, a modified calculation method is proposed to predict the ultimate lateral-moment loading capacity of bucket foundations in sand. The method is validated by field and laboratory test data.The monopile-friction wheel foundation integrates a wheel to a monopile to improve the lateral performance. Two types of wheels, the solid wheel and gravel wheel, are discussed in this part. A series of tests on the monopile, hybrid foundations with solid wheels of different diameters and thicknesses, and single solid wheel foundation were conducted. The results show that the lateral bearing capacity and stiffness increase significantly by adding a solid wheel to the monopile, and the improvement is related to the diameter and thickness of the wheel. An extensive experimental research regarding to the influential factors such as the embedment of the wheel and the vertical load is also presented. By means of FEM, the load transfer mechanism, interaction between the foundation and soil, and the bending moment in the pile are illustrated to study how the solid wheel contributes to the performance of the foundation system. Moreover, the effects of load eccentricity and vertical load are investigated by FEM analyses.The gravel wheel is a ring frame filled with large particles to potentially utilize the gravel or crushed stones in offshore areas. The results of centrifuge tests and FEM analyses demonstrate that the lateral loading capacity of the monopile increases when combined with a gravel wheel, and the improvement depends on the diameter and thickness of the wheel. By means of FEM, the interaction between the pile and surrounding soils and gravel fill are illustrated to interpret the effect of the gravel wheel on the hybrid system. Furthermore, an equivalent layer method adopting the conventional p-y curves is suggested to predict the lateral response of the hybrid foundation. This method is validated by comparisons with the centrifuge tests results. Finally, a case study of the monopile-gravel wheel foundation indicates that the gravel wheel is less efficient in configurations where the ultimate capacity of the hybrid system is dictated by the bending capacity of structures rather than the strengths of soils.

This book provides an overview of floating offshore wind farms and focuses on the economic aspects of this renewable-energy technology. It presents economic maps demonstrating the main costs, and explores various important aspects of floating offshore wind farms. It examines topics including offshore wind turbines, floating offshore wind platforms, mooring and anchoring, as well as offshore electrical systems. It is a particularly useful resource in light of the fact that most water masses are deep and therefore not suitable for fixed offshore wind farms. A valuable reference work for students and researchers interested in naval and ocean engineering and economics, this book provides a new perspective on floating offshore wind farms, and makes a useful contribution to the existing literature.
