Offshore containers play a crucial role in the logistics and operational effectiveness of industries operating in maritime environments, particularly in the oil and gas sector. These specially manufactured shipping containers are used to transport materials and equipment to offshore structures, such as oil rigs and wind farms. They are not similar to standard shipping containers because they can be transported from one container ship to another, or from a ship to a platform, and can withstand the force of banging during transfer.

This blog will explore various applications of these containers, with a primary focus on their importance in the maritime industry and the security standards that govern their design, manufacture, and use.

What is an offshore container?

Offshore containers are a specialized type of container designed to withstand the rigors of complex marine environments. Unlike the standard containers, their resilience helps endure extreme weather conditions, rough seas, and heavy loads. A variety of container types serve different purposes. For instance, cargo containers for general goods, tailored units for specific equipment, and specialized containers for hazardous materials.

These units are entirely portable, and their design ensures continuous use during transportation from one container port to another, ensuring secure operation. These containers come in various designs to serve various specific operational requirements. Here are the major types of containers in the shipping and logistics industry: 

1. Offshore service containers: These are the customized containers built for temporary uses—for instance, workshops, offices, temporary accommodations, labs, power plants, or control stations.
2. Offshore freight containers: These containers transport a variety of goods, including general cargo containers, bulk containers, cargo baskets, gas cylinder racks, and specialized containers. Additionally, portable offshore tanks transport hazardous goods offshore and must also comply with the International Maritime Dangerous Goods (IMDG) Code. 
3. Offshore waste skip: This type of container is mainly used for holding waste, which can be opened or closed whenever needed. They are termed as skids in the oil and gas community, helping to transport various constituents, such as production rigs and drilling equipment, in containers.

Therefore, they also reduce the need for full-fledged on-site construction. This will also reduce labor expenses and time. 

Offshore container certification process

The certification process for the container involves several steps, as it operates outside the country’s borders. Here are the steps in the certification process of offshore containers:  

1. Design appraisal: The design appraisal of the offshore tenants consists of reviewing the infrastructural drawings to ensure adherence to the standards set by the International Maritime Organization. Here are the key aspects of the appraisals:

• The drawing must signify the container size and its maximum load capacity to ensure that it can securely carry the intended cargo.
• The design must also show the corner fittings and closure mechanisms, with the aim of the offshore container manufacturers and constituents to verify the quality and accuracy.
• A comprehensive dataset is required regarding the materials used in container construction, including their grades and properties.

2. Survey: A qualified surveyor inspects the container to ensure that it meets the specific needs. The container inspection includes the following measurements: 

• First is material verification, which means checking and testing the materials.
• Then, the welding is to ensure that welders are appropriately certified.
• After that, you need to review and accept the welding procedures.
• Accept the nondestructive testing procedures.
• At last comes the Identification and Marking Verification for proper categorization of the containers.

3. Testing: Load testing for offshore container type approval needs to be created, and a prototype must be tested according to the approved designs using the same material that will be used for production. 

• The four-point lift test examines the container using all the offshore container lifting equipment. 
• The two-point lift test verifies two opposite lifting points.
• The vertical impact test evaluates the containers’ ability to withstand vertical impacts.
• Lastly, complementary tests for toxic substances are required to adhere to the IMDG code.

Applications of offshore containers 

Offshore containers, a crucial part of logistics that help promote trade across borders, offer several benefits to businesses. Here are some applications of these containers:

1. Maritime research: You can utilize these containers in construction projects, providing a secure storage space for string materials and temporary workspaces. You can also repurpose these containers as office spaces, living quarters, and workshops.
2. Oil and gas industry: The primary application of these containers is in the oil and gas offshore industry. Here, you can use them for transporting tools and supplies to the production platforms, as well as the drilling rigs and equipment.
3. Waste management: These containers collect and dispose of waste, ensuring the secure storage of waste materials and proper disposal. This minimizes pollution risks.
4. Construction and maintenance: You can also utilize these containers for construction projects, providing safe storage for materials and serving as temporary workspaces. Their durability makes them the best structures for temporary housing.

Security standards for the offshore containers

Offshore containers are subject to several security standards to ensure the efficient and secure transportation across borders. Here are the primary security standards for these containers: 

1. International Maritime Dangerous Goods (IMDG) Code: The marine freight containers transfer hazardous materials, adhering to various IMDG regulations. Different safety sets are available to protect various materials.
2. DNV 2.7-1: Det Norske Veritas (DNV) developed this standard, which focuses on the design, manufacture, and certification of offshore accommodation containers. DNV containers also ensure that containers can survive the harsh marine environments.
