Zlnlnll'1 man Centre for Frontier Engineering Re~earch Edmonton, Canada Abstract The Centre for Frontier Engineering Research (C-FER) has just completed a research program devised to assess the shear capacity of a particular composite wall configuration subjected to combined in-plane and transverse loads...

The system consists of a moored body that is completely submerged, and a arbi- trary number and orientation...

... for the overall configuration cases and frequency and of the spatial direction of the possibilities. Starting from the 1st case of oscillations (Chung,1977). In Chung (1976) as square cylinders, the study has been after- far as the floating structures are concerned, wards generalized to the case of circular...

... for a number of configurations. Prellminary experimental results are also discussed. KEY WORDS: Catenary mooring; Mooring dynamics; Moortng experiments INTRODUCTION The importance of taking into account dynamic phenomena in deep water moortng applications has recently led to a revision of the required design...

... seabeds or sediment instability and erosion give rise to critical configurations where pipeline lengths are suspended and exposed to on-bottom currents. The unsup- ported span may respond to cyclic excitation caused by the regUlar shedding of vortices or by wave induced loads. Under unfavourable...

... presents unusual difficulties as a dynamical system because t is a mechanism rather than a simple structural member. As a result It accommodates external loads through substantial shape changes. Thus, the cable configuration is itself an unknown and simulation is nonlinear and very complex. In this work we...
