Yes, There is a solution to ballast water they are helping maintain balance. When the ship pick up cargo at ports in the Great Lakes, their crew dumps the ballast water overboard. Any species in the water end up in the lakes. Answer: Discharge of ballast water in the Great Lakes is conrolled by international accord. In most cases ballast is offloaded to shore side treatment facilities for treatment prior to discharge. On ship treatment is also an option.

Why do ships dump ballast water?
Ships dump ballast water to counter any weight they take on, or to decrease their draft.

What is the difference between segregated and clean ballast tank in tanker?
Clean ballast refers to the ballast stored in a tank not permanently utilized for ballast (see segregated ballast below), but has been cleaned prior to use so clean ballast stored in it, if discharged from a stationary ship into calm water on a clear day will produce no evidence of oil, sludge or emulsion on or under the surface of the water or on adjoining shorelines. Segregated ballast refers to ballast stored in tanks which are permanently utilized for the carriage of ballast, and are completely separated from the cargo oil and oil fuel system.
What is main ballast of a vessel?
Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.
How do you operate ballast pump?
To operate a ballast pump, most commonly you would connect it to a power source, open the appropriate valves to allow water flow, and then turn on the pump to start pumping water in or out of the ballast tank. Always refer to the manufacturer's instructions for specific details on operating your ballast pump.
Why do submarines work?
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.
What is a submarines buoyancy?
A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.
Does ballast water kill the weedy sea dragon?
yes
What is a ballast tank?
A ballast tank is one of several external or internal tanks fitted in submarines, which allow the boat to submerge when filled with water.
Can you use Windshield washer fluid in tractor tires as a ballast?
Hmm, not to sure about that one, but I do know that salt water is usually the best choice. Mix salt, like you would use for making ice cream, and water. Make your solution a heavy salt solution though. This makes for a firmer mix and heavier too.
Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
What changes take place in the ballast tanks when a submarine that has been under water rises to the surface?
The change that takes place in the ballast tank is the chief of the boat flips a switch and pumps the water out of them.
