Abstract

The invention discloses an arrangement method for oil tanks of a bulk cargo ship, which is characterized in that the oil tanks are arranged on boards instead of being arranged at the bottom of the ship, and simultaneously, and a plurality of oil tanks in bilateral symmetry are respectively arranged on the boards on two sides of a hull. Compared with oil tanks of a ship in the prior art, the oil tanks of the bulk cargo ship are arranged on the boards instead of being arranged at the bottom of the ship, so that the danger of collision caused by the fact that the ship strikes on rocks is avoided, and further, risks of oil leakage and pollution can be avoided. Simultaneously, the distance of each oil tank from the longitudinal gravity center of the ship is small, floating state and bending moment changes generated by change of the weight caused by fuel oil consumption are smaller, and total longitudinal strength of the bulk cargo ship is improved. The oil tanks need to be heated before use, the single oil tank is smaller in volume after the arrangement of the oil tanks, and only the required small oil tank is heated individually when in use, so that energy consumption is reduced. The oil tanks arranged on the boards are in bilaterally symmetrical distribution and front-back symmetrical distribution, so that the hull is fine in balance, stable running of the hull is ensured, and the arrangement method for the oil tanks of the bulk cargo ship has fine practicality and is capable of producing excellent economic and social benefits.

Description

technical field

[0001] The invention relates to equipment on a ship, in particular to a method for arranging an oil tank of a bulk carrier. Background technique

[0002] At present, the huge volume of bulk cargo shipping in the world makes bulk carriers one of the most important types of ships in the world merchant fleet. Since the mid-1950s, bulk carriers have generally maintained a strong growth momentum. In the international shipping industry, bulk carrier transportation accounts for more than 30% of cargo transportation. Due to factors such as large cargo volume, sufficient cargo supply, fixed routes, and high loading and unloading efficiency, bulk carrier transportation can obtain good economic benefits, and bulk carrier has become the main force of transportation ships. The dry bulk cargo transported by sea in the world mainly includes coal, iron ore, grain, bauxite, phosphate rock and other bulk cargoes. Bulk carriers can be divided into five representative ship ty...

Embodiment Construction

[0011] The present invention will be further explained below in conjunction with specific drawings.

[0012] Such as figure 1 As shown, there are 6 oil tanks in the bulk carrier, 1 in total, which are respectively arranged on the sides 2 of the hull, and 3 are arranged on one side, and the front, rear, left, and right are symmetrical, and the center position is preferred. An engine room 3 is provided at one end of the ship, and a cargo hold 4 is provided between the oil tanks 1 on both sides. In the bulk carrier of the present invention, the oil tank is moved from the bottom of the ship to the side of the ship, which avoids the risk of hitting rocks and impacts, thereby avoiding the risk of oil leakage and pollution. At the same time, the distance between the oil tank and the longitudinal center of gravity of the ship is small, and the weight change caused by fuel consumption The buoyant state and bending moment changes are small, which improves the overall longitudinal stren...
