The cargo ship ballast tank is arranged in the middle area of a bulk cargo ship, the bulkhead of the cargo ship ballast tank is perpendicular to the broadside of the bulk cargo ship, the bulkhead of the cargo ship ballast tank is of a double-shell structure, the surface of an outer shell of the double-shell structure is flush, and an inner shell of the double-shell structure is used for containing ballast water. The bulkhead of the cargo ship ballast tank, the cargo hold channel and the bulkhead of the cargo ship ballast tank are sequentially arranged in the width direction of the bulk cargo ship. A traditional groove type ballast tank bulkhead is replaced with the ballast tank bulkhead of the double-shell structure, so that the ballast tank can effectively resist the hydrostatic bending moment value of the middle arch of the bulk cargo ship under the normal light ballast working condition, compared with the groove type ballast tank bulkhead, the ballast tank can resist the hydrostatic bending moment value of the middle arch of the bulk cargo ship larger, and the ballast tank bulkhead of the double-shell structure can effectively resist the hydrostatic bending moment value of the middle arch of the bulk cargo ship. And the structural strength of the ballast tank and the bulk carrier is improved. Ballast water is loaded through the bulkhead of the double-shell structure, the ballast water amount is increased, and the requirements for minimum bow draft and propeller immersion under the ballast working condition are met.
本发明公开了一种货船压载舱,货船压载舱设置于散货船的中间区域,货船压载舱的舱壁与所述散货船舷侧垂直设置,且货船压载舱的舱壁为双壳结构,其中,所述双壳结构的外壳表面平齐设置,而所述双壳结构的内壳用于容纳压载水,沿所述散货船宽度方向上,所述货船压载舱的舱壁、货舱通道和所述货船压载舱的舱壁依次设置。通过将传统的槽型压载舱舱壁替换为具有双壳结构的压载舱舱壁,以使得压载舱能够在正常轻压载工况下,有效抗散货船中拱的静水弯矩值,相比于槽型压载舱舱壁来说,能够抗散货船中拱的静水弯矩值更大,提升压载舱及散货船的结构强度。通过双壳结构的舱壁装载压载水,增加压载水量,满足压载工况下最小艏吃水和螺旋桨浸没的要求。
