... and numerical simulation of Haiji-1 mega jacket launch process is presented. Field motion measurements are carried out using Global Navigation Satellite System (GNSS) and Inertial Navigation System (INS) placed on jacket and launching barge. The potential flow theory software MOSES is adopted to simulate...

... ABSTRACT Twin-barge floatover method can utilize two barges to install the topsides and is a promising method for the mega topsides installation. However, the complex connections between the twin barges and topsides pose great difficulties for floatover operation. The installation process...

... elastic plate model is adopted for the ice sheet. A boundary integral equation is constructed, in which the Green function satisfying all the boundary conditions apart from that on the ship surface is adopted. Detailed results for wave loads on a barge ship are provided, which are generally highly...

... for suppressing non-realistic high wave elevation between two floating barges in close proximity. The Damping Lid coefficient is determined through comparing the wave elevation between CFD and BEM results. It is found that the Damping Lid coefficient is sensitive to the wave height and directions. Furthermore...

The floating loadout means that the barge is floating in the whole process of loadout, and the floating state of the barge in the loadout process is adjusted by adjusting the ballast water. The grounded loadout means that the barge "sits...
