And a pump member for generating pressure such that the fresh water moves to the various parts of the marine structure downstream of the filter member in the fresh water supply line.

And a pressurized tank which allows the fresh water supply line to maintain a constant pressure downstream of the pump member in the fresh water supply line.

And a carbon filter for removing fine foreign matter and removing some of the chlorine from the pressurized tank downstream of the fresh water supply line.

And a sterilizer for sterilizing the fresh water downstream of the carbon filter in the fresh water supply line.

The temperature sensor is characterized in that it is formed downstream of the sterilizer.

According to another aspect of the fresh water supply system of the marine structure of the present invention for achieving the above object, in the fresh water supply system of the marine structure, the heat is formed on the outlet side of the fresh water supply line to maintain the temperature of the fresh water It characterized in that it comprises an exchanger.

The heat exchanger is characterized in that it comprises a temperature sensor for sensing the temperature of the fresh water to adjust the amount of cooling water.

According to the present invention as described above, it is possible to reduce the capacity of the cooling device by installing a heat exchanger in the pipe line supplied locally, thereby reducing the cost.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. In addition, the following examples can be modified in various other forms, and the scope of the present invention is not limited to the following examples.

1 is a block diagram showing a fresh water supply system of an offshore structure according to an embodiment of the present invention.

As shown in Fig. 1, the fresh water supply system 1 according to the present invention is a fresh water from the fresh water tank 10 for storing the fresh water to each place 100, such as cabins and engine rooms that require fresh water in offshore structures. The fresh water supply line 20 to be provided, the temperature sensor 30 formed in the fresh water supply line 20 to detect the temperature of the moving fresh water and the temperature sensor 30 downstream of the fresh water supply line 20 It is formed in the heat exchanger 40, the amount of cooling water is adjusted according to the temperature value detected by the temperature sensor 30.

According to the present invention, offshore structures such as drilling vessels and crude oil carriers maintain the temperature of the fresh water supply system 1 at preferably 20 ° C. or lower to suppress microbial propagation in the fresh water, and at the same time, corrosion of the pipes used for the movement of the fresh water. It provides an efficient system to keep the best state to be utilized as drinking water and cooling water supplied to each place 100 of the offshore structure.

The temperature sensor 30 is formed at the outlet side of the fresh water supply line 20 to detect the temperature in the state immediately before the fresh water moving through the fresh water supply line 20 is supplied to the small place 100. do.

The heat exchanger 40 may be a heat exchanger generally used in offshore structures and the like and may use seawater or the like as cooling water. The heat exchanger 40 is formed between the temperature sensor 30 and the outlet of the fresh water supply line 20 so that the temperature of the fresh water immediately before being supplied to the respective places 100 is maintained at 20 ° C. or lower. Heat exchange with fresh water moving the fresh water supply line (20). The heat exchanger 40 increases the amount of cooling water supplied to the heat exchanger 40 when the temperature value of the fresh water detected by the temperature sensor 30 exceeds 20 ° C., so that the temperature of the fresh water is 20 ° C. or less. When the temperature value of the fresh water detected by the temperature sensor 30 is less than 20 ℃ to reduce the amount of cooling water supplied to the heat exchanger 40 to minimize the amount of energy consumption. The heat exchanger 40 is formed of a double tube can prevent the cooling water of the heat exchanger 40 is introduced into the fresh water moving the fresh water supply line 20 even when the tube is broken.
