Key Considerations in Renting Offshore Reefer Containers

Also referred to as DNV containers, reefer containers can handle extreme weather conditions during open sea transportation. 

Hence, we see their continual deployment in exceedingly harsh environments like oil rigs since they are designed to withstand very low minimum temperatures. Additionally, they are constructed with corten steel or wrought alloy aluminium—making them both corrosion-resistant and durable.

What are offshore reefer containers?

Offshore reefer containers are specialised storage units enhanced from standard container storage units to transport perishable and temperature-sensitive goods. For example, seafood, vegetables, fruits, dairy products, medicines and pharmaceuticals, beverages, etc. 

They are expressly designed to maintain consistent internal temperatures and prevent condensation via programmed ventilation systems whilst working in a range of -40°C to +35°C.

As large portable refrigerated containers employed to ship temperature-controlled cargo items, offshore reefer containers are designed for repeated use and transportation of sensitive cargo from one shore to another. 

With their strong steel frames that undergo rigorous testing, they are an obvious solution for transporting cargo safely through an arduous transit.  

Additionally, they can be employed as on-site storage facilities at renewable energy and oil plants due to their strength and stability.

Types of reefer containers

There are two main types of offshore reefer containers. 

These are Det Norske Veritas (DNV) certified containers. DNV is an independent and autonomous organisation that aims to safeguard life and the environment on shore and at sea. 

  1. 8 ft Reefer Container: This is a certified DNV 2.7-1 reefer that constitutes a microprocessor to control the fresh air exchange rate. It also possesses the ability to record fresh air exchange data to help assure consistent product quality.
    It maintains the capacity to protect perishable products against highly damaging CO2 levels in order to control food freshness better. Furthermore, it provides ventilation on demand for perishable cargo in response to the continuing changes in respiratory gases.

  2. 10 ft Reefer Container: Typically DNV 2.7-1 certified, this 10-foot reefer shares similar characteristics to the 8-foot reefer with the capacity to continually record fresh air exchange data. It also provides dynamic venting in response to any continual changes in respiratory gases within the container.

Factors to consider when hiring an offshore reefer container

If you are considering hiring an offshore reefer, there are some important elements to consider before signing the lease papers.

What are the dimensions of the container?

The intended use of the reefer will have a significant impact on the dimensions you choose. For example, if you are considering a reefer for transporting or storing food, you might need twin-room reefer containers that have provisions to chill and freeze simultaneously.

Additionally, you will need independent temperature controls to eliminate the need to hire more than one container. Generally, the standard dimensions for offshore reefer containers are typically 10 or 20ft. However, remember that your dimensions choice will depend entirely on your use case.  

What is the reefer container rental price?

Price can considerably affect your bottom line and overhead costs. So, be sure to investigate different price scales and options when considering the rental of an offshore reefer. 

Where can you ship your rented offshore container?

It is imperative to ensure that whoever you rent from has access to an extensive, global network of depots. Furthermore, ensure that they have long-term relationships with reliable transport suppliers in order to ensure that reefers arrive on time, wherever you need them to be.

Are modifications to the reefer container possible?

Reefer containers should possess the versatility to be modified to suit almost any need. For example, they should have provisions to be fitted with lighting, and power sockets to suit any voltage specifications and shelving units. 

Does it come with the latest technology?

Carefully evaluate the reefer supplier to determine if its solutions come with state-of-the-art technology like Satellite, cellular and GPS-based tracking for complete traceability of your cargo.

What certifications are needed? 

Does the reefer supplier maintain up-to-date certifications such as DNV 2.7-1, ISO 10855 & EN12079? Be sure to ask them to share their certification documentation.

Is the reefer container company reputable?

The reefer company that you’re considering should possess considerable repute, with appreciable experience in the industry. This can help provide you with a sense of calm, knowing that you’re in safe hands. 

Is it a new or used reefer container?

The choice between a new or used reefer container is an important one to make as it can affect the rental price. If the condition of the reefer container is optimal, then a used choice should not be a problem to rent. 

Is the stock immediately available?

Some suppliers run out of stock. So, be sure to inquire if stock is available.  Or if you have to wait for a given period to receive your reefer.

Is there a minimum rental period?

Finally, be sure to find out the minimum rental period as some suppliers impose minimum time period requirements for renting their reefers.


Generally, offshore projects in the renewable energy and oil and gas industry need offshore reefer containers to transport cargo safely and store important foodstuffs efficiently.
