The invention relates to a dual-fuel ultra-large ore carrier, and belongs to the technical field of a ship design. The ore carrier comprises a first cargo hold, a middle cargo hold, an LNG fuel tank and side ballast tanks. LNG fuel tanks are symmetrically arranged in lower areas of ballast tanks on the two side edges of a middle cargo hold area of the ultra-large ore carrier; all or most of the LNG fuel tanks are arranged in an area, close to a tail, of a parallel middle body area of a ship body; and a longitudinal length of each LNG fuel tank is set to be smaller than or equal to the length of a deck between two hatches formed in an upper deck. According to a configuration mode of the cargo hold of the dual-fuel ultra-large ore carrier, under a condition that an extra bulkhead is not added, a huge C-shaped liquid tank can be wrapped in the cargo hold; construction cost of the ultra-large ore carrier is reduced as much as possible, weight of an empty ship is reduced, redundant bulkheads are decreased, and a construction process is simplified; and loading and unloading efficiency of the ultra-large ore carrier is improved, dead corners of the cargo hold are reduced, and one-time loading and unloading of each hatch is achieved.
本发明涉及一种双燃料超大型矿砂船,属于船舶设计技术领域。包括第一货舱、中货舱、LNG燃料罐和边压载舱;超大型矿砂船的中货舱区的两侧边压载舱的下部区域对称设有LNG燃料罐;LNG燃料罐的全部或者大部分设于船体的平行中体区靠近尾部的区域;LNG燃料罐的纵向长度设为小于等于上甲板上设有的两个舱口之间的甲板长度。本发明提出的双燃料超大型矿砂船货舱的构型方式,在不增加额外舱壁的情况下,让巨大的C型液罐得以被包裹在货舱之内;尽可能的降低了超大型矿砂船的建造成本,减轻了空船重量,减少了冗余的舱壁,简化了建造工艺;提高了超大型矿砂船装卸货的效率,减少货舱死角,实现每个舱口均一次性装卸货。
