Part of the offshore navigation path is far away, and a complete living system and a complete power system are required to be equipped on the rolling ship; the living system comprises equipment such as fire fighting, lighting, air conditioning, public broadcasting and the like; the power system comprises power equipment such as a propeller, a diesel generator and the like.
Conventionally, if a roll boat is configured as follows: class 3 passenger ships, class 2 sailing areas, 385 people with passenger quota and double-engine double-propeller, wherein the power of a main engine is transmitted to a distance propeller through a middle shaft and a propeller shaft, the loading capacity of fuel oil can reach 30 tons, and the endurance of the current passenger ship when the passenger ship meets the full-load state and the service sailing speed (Vs=14.0 sear/hour) is 580 sear; because the installation interval of the double paddles is far, two corresponding power oil tanks are usually arranged for storing diesel oil in order to meet the normal operation of the double paddles; in addition, in order to meet the normal operation of living systems on the passenger ro, a corresponding daily oil tank is arranged for storing diesel oil.
Because the volume of the daily oil tank is generally smaller than that of the power oil tank, the diesel oil in the daily oil tank is more quickly lost, and when the diesel oil in the daily oil tank is consumed, the oil quantity detection device in the daily oil tank can send a low oil consumption early warning instruction to the central control platform; the central control platform can randomly transfer diesel oil from any power oil cabin to the diesel oil in the daily oil cabin based on the low-oil consumption early warning instruction, so that the living system can continue to operate.
The inventor finds that if the diesel oil stored in the daily oil tank is too little in the navigation process of the ferry, the central control platform needs to convey the diesel oil into the daily oil tank for multiple times; therefore, how to reasonably allocate the diesel oil storage of the power oil tank and the daily oil tank becomes a problem to be solved.
