Problems solved by technology

[0007] Purpose of the invention: The purpose of the present invention is to overcome the problem that the silt deposits in the ballast tanks of large ships are extremely serious and not easy to remove at present, and the ballast tanks of the newly designed large ships are divided into compartments, so that the sediment can be deposited in the designated and small places, and is easy to remove, thereby reducing sedimentation in double bottom ballast tanks

Abstract

The invention discloses an anti-sediment type large-size ship with new ballast tank separation. A ballast tank is newly separated on a horizontal girder, and a space positioned between an outer plate and a longitudinal bulkhead is separated top and bottom to form the ballast tank in two parts which are a side ballast tank positioned on a broadside and a double-bottom ballast tank positioned at a bottom respectively; and an opening communicated with the double-bottom ballast tank is arranged below an upper deck positioned on the top of the side ballast tank. The invention greatly improves the sediment yield of sludge inside the double-bottom ballast tank of the large-size ship and the removing method and efficiency of the sludge so as to be beneficial to reducing the sediment yield of the sludge, thereby enhancing the carrying capacity of the large-size ship and greatly reducing the operating cost.

Description

technical field [0001] The invention relates to a ship type, in particular to a large ship. By improving the structural arrangement of the ballast tanks, the ballast water is allowed to settle in the predetermined compartments, and the upper clean ballast water overflows to the double bottom ballast tanks, thereby avoiding the deposition of silt in the double bottom ballast tanks. Background technique [0002] The problem of ballast tank silt is a worldwide problem. Due to the high sediment content in the sea area of ​​some large-scale ships, after the ship is ballasted in the port, the silt deposition in the ballast tank is extremely serious. Due to the long-term deposition of silt, the loading capacity of the ship is reduced, the operating cost is increased, the maintenance cost is increased, and the service life of the ship is shortened. [0003] In particular, the double bottom ballast tank has a large area and a complex structure. The silt is distributed on various pos...
