What is a DNV container?
A DNV container is a robust transport container designed and certified according to the strict DNV 2.7-1 and EN 12079 standards for use in the offshore industry.
What does DNV 2.7-1 certification mean?
This is the global industry standard for offshore containers, setting specific requirements for material strength, welding, lifting eyes, and dynamic shock loading.
Why are standard ISO containers unsuitable for offshore use?
ISO containers are engineered for land transport and shipping under mild conditions. They cannot safely withstand the extreme forces (such as drop impact and wave action) on an offshore platform or vessel.
Can DNV containers also be used as standard ISO containers?
Yes, thanks to their standard ISO corner castings and dimensions, they are fully interchangeable within the regular intermodal transport network.
What is the difference between DNV 2.7-1 and EN 12079?
In practice, these standards are largely harmonized; DNV 2.7-1 is the most widely applied and recognized practical standard in the offshore sector.
What is a DNV CSC plate?
This is the official data plate showing both the ISO CSC data, the DNV certification status, and the lifting capacity.
How do I recognize an approved DNV container?
By the official DNV certificate plate, the certified lifting ears, and the unique stampings from a recognized classification society (such as DNV or LR).
What does a Periodic Inspection involve for DNV containers?
Every offshore container must be periodically inspected (usually every 12 months) by a certified inspector to ensure structural integrity.
What steel is used for DNV containers?
Only high-grade structural steel that has been impact-tested at low temperatures (impact-tested steel) is used.
Why do DNV containers have extra heavy corner posts?
To absorb the extreme vertical dynamic forces when containers are lifted or stacked at sea.
What are certified lifting ears?
Reinforced steel eyes welded to the frame and rated for multiple overloading during offshore lifting operations.
Can DNV containers be lifted with a four-leg wire rope sling?
Yes, offshore containers are always lifted using a certified four-leg wire rope sling set combined with certified shackles.
What is the difference between an offshore reefer and a standard reefer?
An offshore refrigerated container features a reinforced DNV frame, ATEX-certified components, and enhanced corrosion protection.
What type of floors do DNV containers have?
Usually galvanized tear-plate steel or hardwood floors, depending on the container type and specific application.
How are DNV containers protected against saltwater corrosion?
By means of a heavy-duty offshore-grade paint treatment (multi-layer coating system with epoxy primer and polyurethane topcoat) or by full hot-dip galvanizing.
What is the maximum stackability of DNV containers?
This varies by type, but they are designed to be stacked multiple highs under dynamic conditions at sea.
What is a DNV Open Top Container?
An open container with a removable tarp or cover, ideal for loading oversized offshore equipment from the top.
What is a DNV Half Height Container?
A reduced-height container specially designed for heavy, compact loads such as drill pipes and heavy tools.
What is a DNV Toolpusher / Workshop Container used for?
As a mobile workshop or office unit on drilling platforms, fully equipped with workbenches, power, and optional overpressure protection.
What is a DNV Mini Container or Cargo Basket?
An open basket structure for the safe transport of smaller, loose goods and gas cylinders to offshore installations.
Are there also DNV Tank Containers?
Yes, these are used for the safe transport of chemicals, fuels, or liquid drilling mud to offshore platforms.
What is a DNV Gas Bottle Rack?
A specially designed and certified frame for safely lifting and transporting industrial gas cylinders at sea.
Does a DNV Reefer Container exist?
Yes, for the temperature-controlled transport of food or sensitive chemicals to remote offshore locations.
Can DNV containers be supplied with internal fixtures or racks?
Yes, they can be customized with lashing points, shelves, and special racks for safe transport.
What is the "Drop Test" in DNV 2.7-1?
A rigorous drop test where a container prototype is tested for impact resistance during a controlled fall..
What should you pay attention to when lifting a DNV container offshore?
Always check whether the wire rope slings and shackles have a valid inspection certificate and whether the sling angle falls within safe limits.
What is the Working Load Limit (WLL) of a lifting eye?
The maximum weight that the lifting eye may safely carry, including dynamic factors at sea.
May personnel be transported in a DNV container?
No, unless they are specifically certified offshore living quarters that meet strict fire and pressure standards.
How are goods secured inside a DNV container?
Through heavy lashing points welded to the inner walls and floor, designed to absorb extreme swaying at sea.
What is a DNV DAF (Designated Anchor Frame)?
A special frame for transporting anchors and heavy offshore anchor lines.
