Abstract
Aiming at the installation height optimization requirement of the key equipment for energy dissipation in the 15000 m3 level trailing suction hopper dredger, which is the first self-developed powered by Liquefied Natural Gas clean energy in China, the influence of the installation height of energy dissipation box on loading efficiency was studied from the perspective of water and sediment movement by means of numerical simulation. It is found that for the target soil, as the energy dissipation box installation height decreases, the loading quality and natural soil quality increase, and the total spillage loss decreases. The results suggest that the optimum installation height of energy dissipation box is 9–10.5 m from the center of the box to the bottom of the hopper. The research can provide a theoretical basis for the design of key energy dissipation equipment of 15000 m3 level LNG trailing suction hopper dredger, the improvement of the efficiency of the loading construction and the reduction of environmental pollution, and also provide technical support for the subsequent construction and transformation of the trailing suction hopper dredgers.
