Since the inception of the shipping industry, the leakage in hatch covers results in serious and massive commercial destruction. The claims made by the wet cargo and shipping industry has perplexed the customers, ship owners, cargo handling companies, their managers and insurance companies. No matter whatever they do or how hard they try, the manual methods and testing techniques, failed to provide complete protection and security against the leaks and cracks which results in the destruction of valuable cargo and goods on board. This often results in the shipping industry paying the millions of dollars in lieu of insurance claims and law suits by the goods companies for the destruction of their cargo due to water. In addition to this, the delays in the shipments, schedule disruptions and sometimes even sinking of ships, are the other factors that cause significant loss to the industry. Sometimes the ships have been even left in the ocean all alone and the crew has to board another ship due to life threatening leaks or cracks in the ship.

All this has resulted in different attempts to control these outcomes due to leakages or cracks in the ships. This lead to the invention and the use of hatch cover ultrasonic tightness testing for checking and verifying the integrity of the hatch covers. This technique has yielded fabulous and promising results. With the invention and formulation of modern techniques and gadgets for this purpose, the ultrasonic testing has gained control over much of the problems associated with hatch leakage at less amount of cost.  The outward shinning and dazzling body of the ship, no matter how heavy and bright it might look, it is bound to get weaken from the site  where it is connected with the other moving parts inside the ship. With the passage of time, the doors, windows, hatch covers, etc, starting developing holes or cracks, which can allow the water seepage in the lower parts of the ship. Due to extensive contact with water and humidity, the protective layering provided by the manufacturers of the ship starts to erode allowing the metal to be directly exposed to the water and humidity.

Therefore, it is a vital duty of the ship manager to maintain the ship and to keep check and balance of the areas which are getting affected by corrosion. It is his responsibility to keep every area of the ship well maintained and well checked for any kind of damages or cracks on regular basis. For this purpose, checking the Tightness of hatch with Ultrasound provides reliable and credible outcomes in less time and spending less amount of energy. The ultrasound scan of the whole ship can be conducted in few hours or if the ship is too big or damaged, it takes one or two days. It does not need large number of men to conduct a test. A single individual can easily conduct it. This saves a lot of money to the shipping company, which might be required otherwise.
