What is the grave dock?
Graving Dock is a device where people can float ships and draw water away to expose the entire body of the ship for maintenance and repair. Also known as dry docks, the tombs are located in shipyards and ports around the world. The technology for their creation was developed separately in several regions of the world, including ancient Greece and China. Although there were some modern improvements, today it would be a grave dock for sailors who lived and worked centuries ago. Ships and ships hover over the gate from the harbor or other waterway. The gate is closed, the blocks are placed under the salary for support and the water is pumped away. The location of the blocks is critical because the ships are designed to float, not to sit on the blocks, and if the blocks are incorrectly shape or size or placed in incorrect places, they can damage the ship. If the ship is not supported by Enough, framing can weaken, or blocks can break through the sides of the ship. Ships are also commonly supported by Graving Dock.
As soon as it is exposed, the ship can be checked. If repairs are needed, it is much easier to do in the grave dock than in the water. The ship can also be lasted to remove algae, Barnacles and other organisms that tend to accumulate, and can be redrawn to protect the torso. Special colors are used on parts of ships that are routine underwater to help resist rot, resis and other problems.
The size and shape of the Graving dock varies. Many early devices were built very narrow to minimize the amount of water to be drawn. Modern docks of graving are larger to suit a number of boat designs. The device can also be covered if there is a need for confidentiality, as with the repair of a military boat. Allitaries may not want to draw attention to people that they are repairing or want to keep the features of their ships hidden for security reasons.
besides that pThey are used for maintenance and repair, grave docks are also used during the boat construction process. The ship is built inside the graving dock and as soon as the hull is completed, it can be floated and mounted, except that it is admitted for the sea tests to confirm that it is eligible for the sea and determines the performance specifications of the ship.
