Why do ships dump ballast water?
Ships dump ballast water to counter any weight they take on, or to decrease their draft.
Are marbles useds for ships ballast?
yes
Toronto Ontario is about 1300 miles from the seayet oceangoing ships can reach its harbor How?
It is conected through the Saint Laurence River
Toronto is about 1300 miles from the sea but oceangoing ships can reach it harbor How?
It can reach the harbor, through the St. Lawrence waterway.
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.
Do ships in the great 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.
Why are zebra mussels located primarily in areas in the eastern US rather than in the western US?
It is generally agreed upon by scientists that zebra mussels entered the Great Lakes from ballast water dumping by large ocean-going vessels from Europe. Ballast water is used to keep ships stable in the water.
Importance of the river?
The Yangzi serves as China's east-west highway. Oceangoing ships can navigate some 600 miles inland to the city of wuhan.
What is permanent ballast in ships?
Permanent ballast in ships refers to the fixed-weight materials (such as concrete or lead blocks) placed at the bottom of a ship's hull to provide stability and proper trim. Unlike removable ballast, which can be adjusted or removed as needed, permanent ballast remains in place for the ship's entire lifespan. It helps maintain the ship's balance and prevents excessive rolling or listing.
Toronto Ontario is about 1300 miles from the sea yet oceangoing ships can reah its harbor how can they do so?
Because the St Lawrence river, the St Lawrence seaway as it is known, is wide & deep enough for ships to navigate the waterway.
What is ballast condition?
Ballast condition refers to the status and functionality of ballast, which is material used to stabilize structures such as railways, ships, and buildings. In railways, it consists of crushed stone or gravel that supports the tracks and facilitates drainage, while in ships, it often involves water or other materials used to ensure proper weight distribution and stability. Proper ballast condition is crucial for safety and efficiency, as inadequate or compromised ballast can lead to structural failures or operational issues. Regular inspections and maintenance are necessary to ensure ballast remains in optimal condition.
What liquid makes ships lower?
Ballast tanks contain water, usually sea water.
