When we leave for an excursion or some long outings, we generally cover our furniture and different valuable things with a material to abstain from being harmed by the dust and moistness noticeable all around. The covers keep the dust particles and the mugginess noticeable all around far from incurring damage to the shine and the surfaces of the things. Likewise when the merchandise is being sent to a far off spot they should be appropriately secured. We take extraordinary consideration in wrapping up the things in plastic or wooden boxes to keep them safe amid the transportation. In any case, by and large where the things are cumbersome, for example, couches, wooden pantries or crude things, for example, wheat (in tons), meat and domesticated animals, wrapping them are impossible.

These immense and cumbersome things are sent through the ocean course in light of the fact that the planes can just convey up as far as possible. Additionally the air passages are nearly too high to be in any way reasonable so it is best to send colossal measures of products through the boats. Transport boats have a gigantic corridor like open space inside where the merchandise are stacked. These corridor like open spaces are known as payload holds and are secured by trapdoor covers which are shut once the load holds are totally filled. They go about as a defensive cover against the very moist sea air furthermore turn into a defensive against the water that could enter because of the high tide or tempests.

Since everything has a breaking point to withstand outside weight, the lid spreads get harmed because of broad utilization. The wear and tear makes gaps of different sizes which then permit the water to leak inside out of the blue. Water leaking inside can make the products get wet and get to be harmed. To guarantee that the seal spreads are okay and there are no openings present in them, the ship's group are encouraged to do a watertight compartment doors testing. The aftereffect of the testing delivers the genuine state of the lid covers. On the off chance that there are gaps present, it implies that there is a high danger of water to enter the load holds.

In such a situation crisis measures are put energetically. The gaps are either secured by a thick plastic or on the off chance that they are not in a position to be secured; the repair group is brought in. They wield new bits of steel on the openings and after that the repair work is affirmed by hatch cover testing with ultrasound. In the event that the gaps are presently totally secured the freight holds are stacked and the boat sets sail.
