The 3 Important Standards Set For A DNV Container

Shipping containers play a crucial role in transporting almost all types of materials from one place to the other. But there is always risk surrounding this transportation that may include spill over, exposure or damage that would not be confined to the said consignment but for the humans in and around, the environment and ecology, Sometimes, these may lead to human fatality too. To avoid or drastically minimize these risks a set of standards have been set that needs to be complied with by the manufacturers of the DNV Container and certified by the certifying authority namely DNV. Once this is done, the container is said to be DNV certified and called as DNV Container

But to get this certification there are a whole lot of standards that need to be adhered to and after due inspection the containers would be duly certified. Let us see some of these major standards.

Materials used - Only metals like aluminum, steel, carbon steel, carbon manganese and their composites are to be used. This is the first security measure to ensure that there is no corrosion, wear and tear and the containers are safe enough to retain the goods loaded in them. Once the containers are offshore, there density due to change of surface may increase thereby increasing the load on the containers. These metals would ensure that they do not give up to the increased pressure.

Design specification - There is a set of dimensions and designs set by DNV which needs to be followed while manufacturing an offshore container. After completion of the manufacturing there would be a pre-certification testing that would be conducted called the Prototype Testing. This includes various testing like Preparation and Calibration, lifting test and the vertical impact test. These are very important keeping in mind the adversities that may be faced on an offshore surface. The container should be able to handle a specified amount of excessive mass weight than its current load which is determined by the lifting test. It should also have no negative impact, cracks, bends or distortion when it falls off from a certain height and when there is turbulence and there is a fall it should be able to tilt to a minimum of 50angle to avoid tripping. This is what is ensured in the lifting test and the vertical impact test.

Certification Validation - Once the certificate is issued it is valid for a certain period but there should be regular inspection of the DNV Container. This should be at least once in a year and after completion of the inspection, the inspection report has to be attached with the certificate. If the inspection is satisfactory the plate would be marked as 'Appropriate'. But if there is any damage to the container, a chance would be provided to repair or renew the damaged parts and another complete testing along with other additional testing, if required would be carried out and the container would be re-certified.

But in case the DNV Container has undergone heavy damage and it is rebuilt or renewed it has to go for a fresh certification and the previous certificate would be marked 'Deleted' and a fresh certificate issued.
