REYES-CASIMIRO, María; FELIX-GONZALEZ, Iván e PEREA, Tiziano. The effect of the design variables of the semi-submersible platform hull geometry on the hydrodynamic response. Ing. invest. y tecnol. [online]. 2021, vol.22, n.3. Epub 03-Ago-2021. ISSN 2594-0732. https://doi.org/10.22201/fi.25940732e.2021.22.3.017.
This research shows the effect of the design variables of the hull geometry of a production semisubmersible platforms on their hydrodynamic response. Hull design variables that are evaluated in this parametric study include: distance between columns (L), column width (B), column height (H), pontoon width (BP), pontoon height (HP), and draft (D). Thus, in this parametric study, 2916 models are analyzed considering three different production volumes (100, 150 and 200 MBD), for each one the amplitude response operators are calculated with the HydroD module of the SESAM computer program. The results show that the draft (D) has a high influence on the amplitude of the semisubmersible response, while the column width (B) has a high effect on the natural period of the system. Additionally, the most probable maximum responses were calculated for different sea states associated with an environmental contour with a return period of 100 years, where it is observed that indeed the variables considered have an important effect on the hydrodynamic response of semisubmersible platforms.
