... and the reaction forces on the legs as output parameters. Subsequently, optimization is performed to determine the appropriate spring stiffness coefficients for the footing legs. To better understand hull deformation mechanism during diagonal preloading, a schematic model is introduced. With that, potential...

... ABSTRACT The safety of propulsion system which is regarded as the heart of ship receives more and more attention by the industry and academia. During the operation of the large vessel, the flexible ship hull could be deformed by the wave excitation more easily than before. The hull deformation...

... of the ships propulsion system and threaten the safety of the ship navigation. Therefore, this paper focuses on the vibration characteristics of the ship propulsion shaft excited by the hull deformation. An experimental test of real ship for the shaft propulsion is taken. During the navigation of the large...

... some peculiarities in the design procedures. The hull deformations due to still water and wave bending moments as well as FPSO motions are important imposed loads to be considered in those structures, besides functional loads. Care should be taken relating to hull deformations in process plant decks...
