20.500.12556/RUL-134889 Ships added mass effect on a flexible mooring dolphin in berthing manoeuvre This paper deals with the hydrodynamic effect of the ship on a flexible dolphin during a mooring manoeuvre. The hydrodynamic effect refers to the change in momentum of the surrounding fluid, which is defined by the concept of added mass. The main reason for the present study is to answer the question, “What is the effect of the added mass compared to the mass of the ship during the mooring procedure for a particular type of ship?” Measured angular frequencies of dolphin oscillations showed that the mathematical model can be approximated by the zero frequency limit. This simplifies the problem to some extent. The mooring is a pure rocking motion, and the 3D study is approximated by the strip theory approach. Moreover, the calculations were performed with conformal mapping using conformal Lewis mapping for the hull geometry. The fluid flow is assumed to be non-viscous, non-rotating and incompressible. The results showed that the additional mass effect must be taken into account when calculating the flexible dolphin loads. added mass conformal mapping Lewis mapping hidrodinamika dodana masa konformna preslikava Lewisova preslikava true false true Angleški jezik Slovenski jezik Članek v reviji 2022-02-10 11:21:17 2022-02-10 11:21:17 2022-09-14 04:10:31 0000-00-00 00:00:00 2021 0 0 21 str. iss. 2, art. 108 Vol. 9 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 532.5:656.61 2077-1312 10.3390/jmse9020108 48410115 RAZ_Grm_Aleksander_2021.pdf RAZ_Grm_Aleksander_2021.pdf 1 2664A401AF2969EBBBC2D9F71CABE631 613724ae9afe1fc5e5143cc9e8eeb31ec1d0da9dbcb08fcb12f4bfa54d67e5ce 44e7f805-8a5b-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153616 https://www.mdpi.com/2077-1312/9/2/108 0 18f41516-8a5b-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153615 Fakulteta za pomorstvo in promet 0 0 0
