Finding leaks in ships and other
marine vehicles is a very tough task. Because the ship’s lower portion
is submerged in water, it causes even more difficulty when the lower
body has to be tested for any weak spots. Small boats can be easily
carried out of the water for inspection, but what would happen to a ship
that is as huge as a building. Yes you are right; the transport ship is
being referred here which has the capacity to carry thousands of
containers on its deck and a thousand goods in its cargo hatches as
well.
Today we have two methods of checking the integrity of the ship. To find the leaks in the ship’s body is a very tough task and it requires to be done accurately to know about the location of every leak in the ship. The two methods can be classified as the manual method and the other one is by checking the tightness of hatch with ultrasound using the gadgets.
The Manual Method
The manual method is the one that comprises of using the human labor. In this process water is pumped on the ship’s body using high pressure motor pumps. The pressure from the pumps creates enough force on the minute holes to make them big enough for the human eye to see. After the water is thoroughly pumped, it is noted from where the water is seeping inside.
At times chalk is also used for identifying the area having holes in it. Chalk is mixed in the water and then pumped on it. Chalk leaves marks after it flows away, this makes it easy for the staff to see where the holes are. The areas are marked and then the entire ship is washed. This process is not only time consuming, but it is also very expensive because it requires many materials to be used in the process.
Using the Ultrasonic Gadgets
The hatch cover ultrasonic tightness testing method is the simplest and the least time taking one. By using the device every area of the ship is scanned and as the scanner reaches a leaking spot it gives a beep. The area is marked and then the repair crew is called in. using this simple and efficient method the entire ship becomes leak free and ready to be used for the next voyage within a day or two or a week if the repair works get delayed.
