In the maritime context, "water" generally refers to the bodies of water that ships and boats travel on, as well as the water that is necessary for the operation of those vessels.
Here are some examples of how "water" is used in the maritime context:
-
Seawater: This is the saltwater found in oceans, seas, and other bodies of saltwater. It is often used as ballast to stabilize ships, and it can also be used for firefighting and cooling.
-
Freshwater: This is water that does not contain salt, such as the water found in lakes, rivers, and some underground sources. Freshwater is used for drinking, cooking, and other purposes on ships.
-
Ballast water: This is water that is taken on board a ship to provide stability. Ballast water is typically pumped in and out of the ship as it travels to maintain its balance.
-
Bilge water: This is water that collects in the lowest part of a ship's hull, known as the bilge. It can contain oil, fuel, and other pollutants, and must be pumped out regularly to prevent pollution.
-
Greywater: This is wastewater from sinks, showers, and other sources that is not contaminated with sewage. It can be discharged into the sea, but must be treated to remove any harmful substances.
-
Blackwater: This is wastewater from toilets and other sources that is contaminated with sewage. It must be treated and discharged in a way that minimizes its impact on the environment.
