DET NORSKE VERITAS (DNV) is an autonomous and independent foundation whose goal is to protect life, property, and the environment at sea and on land. DNV undertakes classification, certification and other verification and consulting services related to the quality of ships, offshore equipment and facilities, and onshore industries worldwide, and conducts research related to these functions.
The DNV 2.7-1 certified offshore container is specifically designed for dynamic hoisting with eye pad devices and DNV certified slings fitted with shackles.
They are checked during the design phase, material procurement, production, and final loading and NDE testing. Not only are prototypes tested, but a specific number of units are randomly selected from each batch for testing at a rate five times the rate of ISO standard container testing.
The containers have a solid steel structure, including floors. They weigh almost twice as much as an ISO container of the same size, which is critical to their ability to maintain an upright position while being transported in rough seas. They must be equipped with DNV approved slings, stronger steel, stricter production specifications and have all the test documentation to prove their reliability in harsh offshore conditions.
