Offshore Compliant Platforms: Analysis, Design, and Experimental Studies
3. New-Generation Platforms: Offshore Triceratops
Download citation file:
This chapter explains the dynamic response of an offshore triceratops in response to the action of regular and random waves. Detailed numerical studies carried out on a triceratops in ultra-deepwater conditions are presented. The behavior of the structure is also compared to the previous experimental and numerical studies carried out on the offshore triceratops. This chapter also explains the behavior of the triceratops in response to the combined action of wind, wave, and current. The response spectra given different degrees of freedom and sea conditions are explained. A detailed methodology for the fatigue analysis of tethers is also presented,...
