Oil ship

Abstract

The invention relates to an oil chip, which comprises shell and several oil chambers. The invention is characterized in that: the oil chamber has water cell and oil cell; the oil cell is arranged with oil tube; the water cell is arranged with water tube; the oil chamber has mover to alternatively select water cell and oil cell. The invention is based on present single-dual shell oil ship, to reduce cost. And since the oil cell and water cell are soft, it can buffer the impact of accidence. The oil cell can be used repeatedly without washing chamber, to reduce pollution. And the mover can fully use space, to improve economic benefits.

Description

technical field [0001] The invention relates to a transport ship, in particular to an oil tanker. Background technique [0002] The existing oil tankers are basically empty one-way transportation. The distance from China to the Middle East is more than 4,300 kilometers. The oil price is 3,500 yuan / ton, and the cost of an empty oil discharge is 3,500×50×15=2,625,000 yuan; according to China’s annual import of 125 million tons of crude oil, the average distribution of the Middle East with 200,000 tons of oil tankers as the standard, a total of 63 oil tankers are needed each year, one-way The total cost of transportation is 63×2625000=1.64 billion yuan, that is, there is a waste of 1.64 billion yuan in the cost of emptying oil every year; in addition, seawater must be pressed into the cargo oil tank on the way back after the cargo oil is emptied to ensure the necessary draft and On the balance, the tank needs to be washed with crude oil for reloading.

[0002] The existing oil tankers are basically empty one-way transportation. The distance from China to the Middle East is more than 4,300 kilometers. The oil price is 3,500 yuan / ton, and the cost of an empty oil discharge is 3,500×50×15=2,625,000 yuan; according to China’s annual import of 125 million tons of crude oil, the average distribution of the Middle East with 200,000 tons of oil tankers as the standard, a total of 63 oil tankers are needed each year, one-way The total cost of transportation is 63×2625000=1.64 billion yuan, that is, there is a waste of 1.64 billion yuan in the cost of emptying oil every year; in addition, seawater must be pressed into the cargo oil tank on the way back after the cargo oil is emptied to ensure the necessary draft and On the balance, crude oil needs to be used to wash tanks for reloading. On the one hand, it increases the cost, and on the other hand, it also increases the chance of crude oil entering the sea, causing pollution to the marine environment.

In order to solve the existing problems, double-hull oil tankers have been developed, and special ballast water tanks have been opened in the space between the double-hulls, which has solved the problem of marine environment pollution, but it still cannot be solved. The problem of transportation cost caused by one-way empty discharge

[0003] In the Chinese invention patent specification CN02122755.1 issued on July 12, 2006, a method for using the hull structure of a tanker for transporting oil and fresh water is disclosed. The tanks are all used as fresh water tanks. In addition, two dual-purpose tanks for ballast seawater tanks and fresh water cargo tanks are set in the center of the hull, which can transport oil cargo on the outbound journey and transport fresh water on the return journey. However, this method only changes the original ballast tank into a fresh water tank, and the space of the cargo oil tank is not used during the return journey, and the available space of the fresh water tank is relatively small, resulting in little economic benefit, and This structure is only suitable for tankers with double hulls, and the application range is not wide
