Compliant offshore structures, by yielding to wave and current actions, avoid unacceptably high hydrodynamic loads leading to economic designs and thus have always been favored for deep sea water operations. As these structures have large displacements with inherent non-linearities, so prediction of behavior of these structures in oceanic environment along with earthquake loads is difficult and...

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 values of response from spectral modeling approaches. The interested reader can then exp...

Maritime structures were traditionally designed for static maximum loads (design loads). However, ship and offshore structures are very much subject to dynamic loads, coming from, Fig.1: propellers and diesel engines excite elastic vibrations in local structures. The number of load cycles is usually much higher than for those due to seaways. Seaways excite local changing pressures. Typical freq...
