Checking Tightness of Hatch with Ultrasound Hatch Cover Tester Is a Routine on Navy Ships

One of the biggest prized possessions of the United States is its navy. It is one of the biggest among all the other countries and it comprises of the most advanced ships, submarines and staff. Comprising of hundreds of small and many gigantic ships, it houses thousands of troops who spend most of their careers out in the oceans protecting the boundaries from all unwanted menaces. On the governmental note, managing the huge fleet is not an easy task. The ships and all other transports used by the naval staff should be faultless. Because of their nature of work, every machine is at risk of corrosion because of the salty and humid air of the oceans.

The navy ships have hatch covers just like a normal commercial transport ship. The only difference between the two is that the transport ship carries consumable goods in its cargo holds while the navy ships carry missiles and bombs in its cargo holds. Like every other ship out in the ocean, the hatch covers of the navy ships also develop leaks which can be very dangerous especially when the cargo holds are filled with explosives. To stay ahead of any disturbance in their warfare activity, the Hatch Cover Ultrasonic Tightness Testing has been made a daily routine.

A special team has been assigned the task to run the test on every ship on a daily basis. This keeps the ships clean and free from corrosion at all times. Since a navy’s ship is equipped with much more things than a civilian ship, the testing procedure can take a lot more time than on a civilian’s ship. There are a thousand movable parts that need to be checked and oiled regularly to ward of corrosion. The different parts of the ship are tested for leaks, and the cabins are also checked for leaks on a regular basis.

Protecting the explosives is a very crucial task of the crew on board. No leak can be accepted in the cargo hold that comprises of explosives and the fighter planes. Any wetness can easily cause it to malfunction which would be a disaster in times of emergency. The checking of tightness of hatch with ultrasound is even done twice a day if there are any doubts of leaks emerging after the first test has been conducted. Usually leaks occur due to the humid air, water and the cracks that appear from the wear and tear caused by the moving of cargo or loading and unloading. If any cargo is moved from one hatch to another, the officers may ask for the test to be conducted again just to be sure that nothing has been damaged.
