EJSE Special Issue: Loading on Structures (2007) Introduction to the Analysis and Design of Offshore Structures– An Overview N. Haritos The University of Melbourne, Australia ABSTRACT: This paper provides a broad overview of some of the key factors in the analysis and design of offshore structures to be considered by an engineer uninitiated in the field of offshore engineering. Topics covered range from water wave theories, structure-fluid interaction in waves to the prediction of extreme val- ues of response from spectral modeling approaches. The interested reader can then explore these topics in greater detail through a number of key references listed in the text. 1 INTRODUCTION mands in terms of hydrodynamic loading effects, foundation support conditions and character of the The analysis, design and construction of offshore dynamic response of not only the structure itself but structures is arguably one of the most demanding also of the riser systems for oil extraction adopted sets of tasks faced by the engineering profession. by them.
