Equipment Cooling With Sea Water

The heated fresh water coming from the engine and the sea water circulating in plate heat exchangers are cooled and sent back to the engine and other equipment.

Equipment Cooling With Sea Water method used for temperature reduction. Using seawater for equipment cooling is a widely preferred method, especially on large ships. Seawater has a large cooling capacity and can be used as a natural coolant.

There are two basic methods of cooling equipment using seawater: direct seawater use and closed-loop cooling with seawater.

1. Direct Seawater Use: In this method, the equipment is cooled directly by seawater. Sea water is brought to the equipment with the help of a pump and heat transfer is provided. In this method, the seawater must be filtered and cleaned because the salts and sediments found in the seawater can damage the equipment. In addition, appropriate precautions must be taken to ensure that organisms present in seawater do not damage the equipment.
2. Closed Circuit Cooling with Seawater: In this method, seawater circulates in a closed-loop system and indirectly cools the equipment. As the seawater passes through the equipment with the help of a heat exchanger, heat transfer takes place. In this method, problems caused by salt and sediments are minimized since the equipment does not have direct contact with sea water. In addition, appropriate measures must be taken to prevent organisms found in seawater from entering the system.

Equipment cooling with seawater can be an environmentally friendly option because it uses seawater, a natural coolant source. However, the use of seawater also has some potential disadvantages. These include factors such as salts and sediments in seawater can damage equipment, seawater can cause corrosion, and the need for seawater infrastructure to be installed and maintained. Therefore, careful consideration and appropriate precautions should be taken when selecting the method of equipment cooling with seawater.
