Experimental and numerical investigation of wave induced motions of partially submerged bodies approaching a fixed structure

Wave Induced Motions of Irregular Shaped Ice Mass close to Fixed Structure

“…Also as the ice mass approaches very close to the platform, the motion slows down in surge direction and the motions in heave direction increase. All these results are consistent with the recent findings by Sayeed et al [19,20] and the ratio of separation distance / wavelength is found to govern the corresponding kinematics of the ice mass.…”

“…The hydrodynamic interaction between the offshore platform and iceberg the in near proximity is an influential factor which effects this impact load. Experimental data [18] on the free floating motions of an irregular ice mass approaching a fixed structure is reanalyzed following the same procedure as [20] which reveals consistent results with all the recent studies. It is evident that the motions of the irregular shape ice mass also follows the same patterns like the spherical and cylindrical models.…”

“…For the rest of the waves, the ice model had either single or multiple impacts with the platform before moving around and passing the platform. Sayeed et al [19,20] identified strong influence of standing wave on the kinematics of ice masses in front of fixed platform. When the incoming wave is obstructed by a vertical wall, the waves get reflected from the wall.…”

“…It was also found that surge RMS forces decreased and heave RMS forces increased when the model was very near to the structure. Sayeed et al [20] conducted free floating experiments with the same models and same fixed platform. The wave induced motion data showed similar trends as obtained in [19].…”

“…The impact velocity and near vicinity hydrodynamic interaction significantly effects the impact load. In recent studies, Sayeed et al [19,20] . [20].…”
