The invention relates to a self-propelled trailing suction offshore ore mining ship. The ship is provided with an offshore ore mining operation system. The self-propelled trailing suction offshore ore mining ship comprises a single suction pipe, an underwater ore suction pump, an ore screening box, a loading device, an ore hold, a dehydration system and a dry unloading system; and ore is mined through the single suction pipe, sucked in by the underwater ore suction pump, roughed by the ore screening box and then loaded into the ore hold through the loading device, the ore is washed with washing fresh water after being precipitated, then dehydrated through the dehydration system at the bottom of the ore hold, and after the ship runs to a designated ore unloading place, the ore is conveyed to an ore field through the dry unloading system consisting of a grab machine and a belt conveyor. A full-electric driving system is adopted, power distribution of a power device can be flexibly carried out in different environment conditions and different operation working condition ranges, a generator set can reach a proper power load state, proper power storage is achieved, fuel consumption is low, and environmental protection and energy saving are achieved.

    本发明涉及一种自航耙吸式近海矿砂开采船,船上装有近海砂矿开采作业系统,包括:单耙管、水下吸砂泵、矿砂筛选箱、装舱装置、矿砂舱、脱水系统、干式卸载系统;通过单耙管开采矿砂,并由水下吸砂泵将砂矿吸入,经矿砂筛选箱粗选后再通过装舱装置装入矿砂舱,矿砂沉淀后用冲洗淡水对矿砂进行冲洗,再通过矿砂舱底部的脱水系统进行脱水,行驶至指定的卸矿地点后,通过由抓斗机、带式输送机组成的干式卸载系统将矿砂输送至矿场;采用全电力驱动系统,在不同环境条件、不同作业工况范围中,均能够灵活地进行动力装置功率分配,使发电机组达到合适的功率负荷状态,并有适宜的功率储备,燃油消耗低,环保节能。
