Perhaps you might also have this question: "Offshore containers and standard shipping containers look quite similar in appearance, but why is the price difference so huge?" Could it be simply because offshore containers have better corrosion resistance? Next, Container Family will address this issue.

The common standard shipping containers include 20ft and 40ft sizes. Their main function is for transportation. The design is relatively simple, without complex accessories or internal layouts, and they can be stacked multiple layers. While offshore containers are specifically designed for offshore operations, they can be placed outdoors for a long time and have excellent corrosion resistance.

There are build strength and quality differences, but offshore containers must be certified by DNV and are thicker, heavier and have more features as well such as customized interior layout,specialized lift points and shackles as opposed to 'standard' cast corners... it comes down to strength for our applications, but some of the extra cost comes from being certified.

A Table to Show the Differences Between the Two Kinds of Containers:

Item
 Offshore Container
 Standard Shipping Container
Design and Usage Purpose
 Designed for offshore operations, such as oil and gas extraction, etc., it needs to have the ability to withstand harsh marine environments and withstand high-intensity usage.
 Designed for conventional land transportation and maritime shipping, it focuses on the durability of the products and must comply with international logistics requirements.
Size
 Customized for specific offshore operation,usually smaller than the standard shipping containers.
 The common sizes are 20ft,40ft,45ft.
Loading Capacity
 Built to carry heavier load relative to size.(The safe weight is 25000kg)
 Max gross weight is typically 30480kg(20GP).
Lifting and Handling
 The container body is welded with special heavy-duty lifting ears on all sides, equipped with steel wire ropes, and four points are synchronized for soft lifting.
 Standard ISO four-corner fittings, for crane lock lifting at the dock.
Waterproof
 Multi-layer sealing + anti-wave drainage structure, resistant to seawater erosion and heavy rain soaking.
 Single-layer rubber door seal, with basic rainproof and waterproof functions
Anti-corrosion Treatment
NORSOK M-501 multi-layer anti-corrosion sandblasting coating, with a marine service life of up to 10-25 years
 Regular marine anti-rust paint doesn’t easily rust in the short term.
Stack
 At most, only two layers of stacking are allowed, and the lifting devices cannot be dismantled.
 Multi-layer stacking permitted inside holds;extra lashing required for deck stacking
Certificate
 DNV 2.7-1,ISO,CSC
 ISO,CSC


The standard ISO shipping container is a globally standardized land sea freight container that is lifted from the dock using a crane at the four corners; the offshore container is a special anti-shock equipment unit for offshore operation,equipped with dedicated lifting ropes,heavy corrosion prevention,and ship classification society safety certification, is specifically used for lifting between platforms and supply ships.

So why the offshore container is much more expensive than the standard shipping container?The specific lifting ropes,heavy corrosion-resistant coating,DNV certification,more durable material and structure,strong customization,all the features mean the offshore container will be more expensive.
