を設は生活物資の補給を行っていた。[Prior Art] As shown in Figure 2, semi-submerged offshore facilities usually use a floating body and ballast tank a submerged in the sea to support the upper structure above the water surface, and in the event of rough weather, the wave height can be adjusted. When the temperature rises, the facility manager or full-time operator drains the seawater in the ballast tank a and lifts the superstructure upwards (arrow C).
), the air gap d is increased and the upper structure is placed on platform e1 (if', etc.) to prevent waves from passing through them, and later, when the weather improves, the air gap d is reduced to keep the superstructure in a good stable state. Therefore, in conventional offshore facilities, it was necessary to always have a manager on site in case of changes in sea conditions, and living facilities were set up for this purpose and replenished with daily necessities.

It was designed to provide a semi-submerged multi-purpose facility that can save on water. In a multi-purpose facility, there is an unmanned receiving device that receives signal radio waves sent from a control facility on land or water and emits an electrical signal, and the floating body and ballast receives electrical signals sent from the receiving device. It is equipped with a control device that automatically operates the tank, drainage system, and related equipment.
