There are the following differences between a 10FT DNV 2.7-1 offshore refrigerated container and an ordinary refrigerated container:

Design standard

10FT DNV 2.7-1 offshore refrigerated container: follows the DNV 2.7-1 standard, which has strict regulations on the structural strength, material selection, and lifting methods of containers to adapt to the harsh offshore environment, such as stipulating that the design temperature is not higher than -20℃.

Ordinary refrigerated container: Generally designed according to standards such as ISO 1496, mainly considering the versatility in conventional land and sea transportation environments, and the requirements for structural strength are lower than those for offshore refrigerated containers.

Structural design

10FT DNV 2.7-1 offshore refrigerated container: usually adopts a more solid structure, and the key parts such as the lifting lugs are designed with higher strength and can withstand greater lifting stress. Some open-top containers also need to add a hard top or a flexible top cover. The hard top should be non-slip and able to withstand a certain amount of pressure. The flexible top cover should also be able to withstand the corresponding weight. There is a warning on the edge of the top of the container.

Ordinary refrigerated container: The structural design mainly meets the conventional transportation and loading and unloading requirements. The lifting method is usually through corner pieces or fork grooves. There is no special reinforcement of offshore refrigerated containers for the harsh offshore environment in terms of strength design.

Material selection

10FT DNV 2.7 - 1 offshore refrigerated container: In addition to considering general strength and corrosion resistance, it pays more attention to the low-temperature toughness of the material to prevent brittle fracture in low-temperature environments and possible collisions. Stainless steel and low-temperature resistant steel are often used.

Ordinary refrigerated container: The materials used have relatively low requirements for low-temperature performance. They consider more costs and performance in conventional environments. General corrosion-resistant materials can meet the requirements.

Refrigeration system

10FT DNV 2.7 - 1 offshore refrigerated container: In addition to having good refrigeration performance, the refrigeration system must also adapt to the vibration, turbulence and other environments at sea, and have higher stability and reliability. Some models are equipped with a microprocessor-controlled fresh air exchange system, which can accurately control the air exchange rate according to the cargo and environmental requirements and record relevant data.

Ordinary refrigerated container: The refrigeration system mainly meets the conventional temperature control requirements, is relatively weak in stability and resistance to harsh environments, and usually does not have such precise fresh air exchange control functions.

Application scenarios

10FT DNV 2.7 - 1 offshore refrigerated container: Mainly used in offshore oil and gas industries, between offshore platforms, and offshore fisheries, etc., to transport goods that require refrigeration such as daily necessities, medicines, seafood, etc.

Ordinary refrigerated containers: Widely used in land and sea transportation around the world, including long-distance international trade, inland transportation, etc., serving various cargo transportation scenarios that require refrigeration and preservation, but less specifically for special offshore environments.
