Publisher's Synopsis
Intermediate foundations are used for anchors, as foundations for tension leg platforms and 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, and can be embedded into the seafloor with embedment ratios L/D of between 0.5 and 10.
The first chapters introduce the foundation type, compare shallow, intermediate and deep foundation models and design, state the unique design issues which make intermediate foundations radically different from shallow and deep foundations, and list their hazards which can mainly occur during installation. Later chapters cover installation, in-place resistance and in-place response, then miscellaneous design considerations.
There is no general agreement as to which design methods / models are appropriate, and a theme of this book is that models should only be as accurate as the data. Hence a number of reasonably accurate models are provided, together with comprehensive discussion and advice. Several example calculations and over 200 references are also included.
This is the first ever book dedicated to the geotechnical design of intermediate foundations book, and it will appeal to professional engineers specialising in the offshore industry.
