A loose ship is a sinkable ship. A ship irrespective of its size and weight can only stay afloat as long as it is completely leak proof and leak free. Leaking ships are sinkable even by the slightest wave that hits it. There is no guarantee how long a ship can stay on the surface as long as its many parts are leaking. Apart from the sinking factor, a leaking ship can be the greatest threat to the condition of goods it carries. When the hatch covers are leaking, water can easily enter the cargo holds and destroy all the goods that are inside the cargo holds.

It is advised to check tightness of hatch with ultrasound whenever the ship has made a tiresome voyage. Most of the ships are gone through many blows and rough treatment because the heavy chains that lower and extract the heavy goods from the cargo holds easily scrape the hatch covers and other areas of the ship. The scraping of the heavy chains clearly damages the paint on the ship’s body. As soon as the ship’s protective paint is worn off, the ship’s iron body is exposed to the air and water. Since the humidity is at the extreme levels at sea, it quickly catches rust.

The rusting process in this climax is very speedy. It quickly eats away the layers of the iron body leaving behind a clear hole. This hole can be of any size there is no restriction to the size of the hole that can be created, it all depends on the layers the rust has managed to access. The presence of holes clearly allows water to enter the ship’s different areas which can easily ignite a spark or a short circuit. The spark can result in a fire inside the ship or it can also blow a great hole in the ship’s body and the result will be nothing less than the ship to sink and be never usable again.

Hatch cover ultrasonic tightness testing allows the staff to learn about the holes and their location. When the intensity of the holes is learned and their locations are also found, it is very easy to apply the repairs and keep the integrity of the ship intact. As the ship is leak proof, there is no way the cargo it carries can be harmed in any way. When the external forces are unable to penetrate the tough walls of the ship’s hatch covers the goods kept inside are safe and can be unloaded without the fear of any damage during the voyage.
