  • Ballast water system:A ship ballast water system is used to stabilize a vessel by taking on water into ballast tanks, which helps to maintain the ship’s stability and balance. Ballast water is typically taken on when a ship is empty or partially loaded, and it is discharged when the ship is loaded with cargo. However, ballast water can also contain a variety of organisms, such as bacteria, viruses, and small marine animals, which can pose a risk to the environment and to human health if they are introduced into new ecosystems. As a result, international regulations have been established to ensure that ballast water is treated and managed properly to prevent the spread of invasive species and other environmental threats. Ships are required to have ballast water treatment systems installed to comply with these regulations, which typically involve the use of physical, chemical, or biological methods to remove or neutralize harmful organisms and other contaminants in the ballast water. Proper management of ballast water is critical for protecting the marine environment and maintaining the sustainability of the world’s oceans.

 

  • Refrigeration system: A refrigeration system on ships is a vital component that is responsible for maintaining low temperatures for food storage and preserving cargo. Refrigeration systems typically use a combination of compressors, condensers, evaporators, and refrigerants to remove heat from the air or water within the cargo space and discharge it outside the ship. On ships, refrigeration systems are used to maintain the temperature of perishable goods such as meat, fish, fruits, and vegetables. Refrigeration systems can also be used to maintain low temperatures in cargo tanks carrying liquefied gases such as ammonia or liquefied natural gas (LNG). The refrigeration system is typically designed to meet the specific requirements of the ship and its cargo. The size and capacity of the system will depend on the size of the ship, the volume of cargo to be refrigerated, and the temperature requirements of the cargo. The system must be carefully maintained and serviced to ensure it operates efficiently and safely. In addition, refrigeration systems on ships must comply with international regulations, such as the International Maritime Organization’s (IMO) International Convention for the Prevention of Pollution from Ships (MARPOL). These regulations are in place to minimize the environmental impact of refrigerants and ensure the safe and proper handling and disposal of refrigerants.

These are just a few examples of the types of machinery and equipment that can be found in the engine room of a commercial ship. The specific configuration and equipment may vary depending on the size, type, and purpose of the vessel.
