Security equipment is provided in each of the plurality of holds, and each of the security equipment is provided with an attitude control device having a ballast adjustment function, a fire door, a fire extinguisher, an insulated door, and a watertight door. And a central control means are electrically connected to these sensors and the security equipment, respectively, and the central control means determines abnormality contents based on an output signal from the sensor. Then, an operation signal is output to the corresponding security equipment based on the determined abnormality content to activate them. [Operation] The marine vessel control device according to the present invention, by adopting the above-described configuration, concentrates output signals from the respective sensors on the central control means, and based on these signals, the central control means determines the content of the abnormality and the degree thereof. Judgment and output an operation signal to the security equipment directly responding to this abnormal situation and take action, and output an operation signal to all other equipment to be controlled in connection with this abnormal situation and simultaneously output these To control. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes an oil tanker (hereinafter simply referred to as a tanker) as a ship to which the present embodiment is applied. The tanker 1 has a hull section divided into a number of hold spaces (compartment rooms) 3 (3a to 3h) and an engine room 4 by a number of bulkheads 2 and a rear area provided behind the upper deck of the hull section.

The central control means 7 discriminates the content of the abnormality based on the content of the abnormality and outputs an operation signal to the corresponding security equipment 6 based on the content of the determined abnormality. In the present embodiment, each of the sensors 5a to 5j has a function in which a temperature detection function, a smoke detection function, a pressure detection function, and a liquid level detection function are combined. Output. The security equipment 6 includes a posture control device having a ballast adjustment function, a fire door, a fire extinguisher, a heat insulating door, a watertight door, a device operation switching device, and the like. The central control means 7 is installed on the bridge, and includes a CPU 8, a display 9, a keyboard 10, a printer 11
The temperature and smoke in each of the holds 3a to 3h, the engine room 4 and the bow H are detected based on the signals from the sensors 5a to 5j to detect the presence or absence of a fire. And the like, and by detecting a change in the liquid level to detect inundation or leakage, to determine the nature of the abnormality, its occurrence position, and its scale. The central control means 7 is preliminarily provided with a program for the type and procedure of the anticipated abnormal situation, and sends an operation signal to the corresponding security equipment 6 based on the type, location and scale of the abnormal situation. Output. Next, the operation of the thus configured marine vessel control device of the present embodiment will be described as follows, taking as an example a specific example of the abnormal state when water is immersed in an empty ship. For any reason, for example, when a crack occurs in the hold 3b and water is generated in the hold 3b, a rise in the liquid level in the hold 3b due to the flood is detected by the sensor 5b,
The information is output to the central control means 7. When the information regarding flooding is sent to the central control means 7, an operation signal is output from the central control means 7 to the security equipment 6 provided in the hold 3b, and the watertight door is closed, whereby the hold 3b The other hold 3 is isolated in a watertight state. On the other hand, along with the separation operation of the hold 3b, an operation signal is output to the attitude control device, and the ballast adjustment mechanism is operated, thereby correcting a change in attitude caused by flooding. Such attitude control is gradually performed according to a change in the amount of water sent from the sensor 5b, and appropriate attitude control is obtained.
