Offshore Tank Container vs Offshore Container: What’s the Difference & How to Choose?

Containers are part of various industries that carry all types of material anywhere. When working in offshore industries like oil and gas, marine logistics, or chemical transport, the right manufactured container can offer safety, efficiency, and compliance. Two primary types used in these settings are offshore tank containers and offshore containers. 

Like their quite similar names, many people consider them the same thing, but that’s not the case. Both containers serve different purposes as having distinct features to fulfil the specific needs of the offshore industry. 

Before deciding between offshore tank containers and offshore containers, it’s important to understand the differences to learn which container type will work best for your offshore product transportation needs. We also focus here on the high-quality options provided by NTtank. 

What is an Offshore Container

Offshore environment is always harsh because of exposure to high degrees and saltwater. High-quality containers are big requirements to transport goods through sea. Such quality containers can withstand harsh offshore environments and rough handling during material transportation processes. 

From material to manufacturing methods, manufacturers especially pay attention to each detail. Most containers have a steel or aluminum body and are safe and reliable to use in offshore conditions. They have certification to standards like DNV 2.7-1 and EN 12079 are the only reliable options. 

Key Features

• They are durable enough to work in extreme weather and wrong material handling.
• High-quality to safely transport goods over long distances
• They fulfil international standards of safety like DNV 2.7-1 and EN 12079

Offshore Containers Types 

Offshore containers are of different types, depending on the product they carry. 

• Freight Containers: Carry normal cargo and tools for transporting.
• Service Containers: Customized units designed for specific tasks, like workshops or laboratories.
• Waste Skips: They collect and transport waste materials.
• Basket Containers: Transport large or irregularly shaped items in open containers.
• Refrigerated containers or reefers: Keep and transport things that require a cold temperature.. 

What is an Offshore Tank Container

Offshore tank containers are a specialized type that transports liquids and gases in offshore environments. Intermediate Bulk Container or IBC is another name for such containers. Liquids and gases are mostly hazardous and require tank containers that can safely handle hazardous materials. Industries that require the transportation of chemicals, fuel, or potable water are in dire need of such tank containers. 

Offshore Tank Containers Key Features

• Made from materials like stainless steel to resist corrosion and offer durability.
• Liquids and gases are difficult to handle, so these tank containers are cylindrical in shape within a frame. It prevents spillage of transporting material and facilitates easy handling.
• Adhere to international standards for transporting hazardous materials.
  • IMDG (International Maritime Dangerous Goods)
  • ADR/RID (European Agreement concerning the International Carriage of Dangerous Goods by Road/Rail)
  • DNV 2.7-1
• Tank containers have various safety features, from safety relief valves and overpressure protection to anti-surge mechanisms to handle volatile substances safely.

Tank containers are reliable and extra efficient in transporting hazardous liquids safely. They are highly required in industries like oil and gas, chemicals, and marine logistics.

Offshore Tank Container Types

• Chemicals are hazardous and non-hazardous and need chemical tanks for their efficient and harmless transportation.
• Fuel tanks are safe to carry fuels like diesel or gasoline.
• Carrying potable or industrial water is possible worldwide securely in Water tanks.

Offshore Tank Container vs Offshore Container: Detailed Comparison

Offshore containers and offshore tank containers serve different purposes. A thorough comparison shows there is a big difference between the two container types. 

Purpose

An offshore container carries general goods and tools to and from various locations and offshore ones like oil rigs, ships, and platforms. They can carry almost anything from solid to waste material and personal belongings. 

Offshore tanks carry liquids and gases safely in offshore environments. They are safe enough to carry hazardous or non-hazardous fluids like chemicals and fuels.

Structure

Offshore containers have strong frames and solid walls. It has doors to easily load and unload material. The main aim behind its design is holding and protecting a variety of dry cargo.

An offshore tank is similar to a tank with a body of stainless steel. It has protective frames around the body for easy loading and unloading. It efficiently and safely holds liquids under pressure or temperature-sensitive materials with the help of valves, gauges, and pressure release systems. 

Safe

Offshore containers have material that makes them strong enough to handle rough offshore weather like high winds and saltwater waves. They have lifting points that allow easy and safe loading and unloading of liquid at sea. It complies with all international safety standards for offshore use.

Offshore tank containers also have all these safety features. Manufacturers also added some extra safety features in tank containers as they are handling hazardous materials. Safety valves and emergency vent systems are some of the efforts in this regard. These tanks have pressure relief valves to withstand internal pressure from liquids and gases. The material has a special coating to resist corrosion from chemicals. 

A container carrying tools must be strong, but a container carrying diesel needs extra safety measures in case of leaks, fire, or pressure changes.

Material 

The two containers have different materials in their formation according to their intended use. Offshore containers have carbon steel with heavy-duty paint to resist corrosion. The material and construction make sure the container offers strength and durability during transportation. 

Offshore tank containers have bodies made from stainless steel, which offer resistance to chemical corrosion. They have an outer frame made of steel to protect the tank inside. Some special tank containers have insulated designs for transporting temperature-sensitive liquids.

Safety Standards

Both containers have different safety standards, such as offshore containers, which must have lifting strength. They must be resistant to drops and impacts. Offshore tank containers are built strong and tested for pressure and leaks. 

Cost

Offshore containers carry solid goods that are easy to transport and demand less safety, which makes them less expensive. 

Offshore tank containers cost you a lot of money because of their special materials and safety features. The cost does not seem too high when you know how important it is to carry dangerous liquids or gases safely. 

Maintenance Requirements

Offshore containers require repainting to protect against salt corrosion. You need to regularly inspect the containers to find any dents, rust, or damage to its body.

Offshore tank containers have some important parts, like safety valves and pressure systems, which require detailed inspections. Immediately repair any minor damage that occurs to the tank body to prevent leaks. You have to test tank containers regularly for pressure and leaks. 

Offshore Tank Container vs Offshore Container: Key Differences

You know your specific offshore needs, and after reading this thorough difference, you can select the appropriate container.

How to Choose the Right Container for Your Offshore Operations

Which container will work best for your task depends upon several factors:

Assess the Nature of Your Cargo

The first important thing is the item you need to carry and transport in the container. An offshore tank container is necessary to carry and transport liquids and gas substances, like chemicals, fuels, or water. You can use an offshore container for general cargo, which is solid, like tools and equipment. 

Consider Environmental Conditions

It is necessary to understand environmental conditions before selecting your cargo container. The sea environment is different from land, and containers have to bear harsh weather conditions there, like high and low temperatures and strong winds. Saltwater and sea sprays further add up in tough conditions. You can pick your container depending on your cargo nature, like 

• Temperature-sensitive materials need containers with insulation or refrigeration capabilities
• Volatile liquids and gases need tank containers 
• Hazardous materials need tank containers.

Regulatory Compliance

The best container meets all necessary certifications and standards relevant to cargo and destination. This includes compliance with international regulations like IMDG and ADR/RID for hazardous materials.

Size and Capacity

What’s your cargo volume and dimensions? When you find the correct numbers, you can pick the right container—overloading or underutilizing a container results in inefficiencies and potential safety hazards.

Customization Needs

Every industry and every business has its own requirements according to its cargo material and size. These requirements bring the need for containers with specialized features such as heating systems, insulation, or specific fittings. A customized container can meet your operational needs. 

Check Safety Features

One must check the safety features when selecting offshore containers. However, they are most important when transporting hazardous liquids and volatile gases in offshore tank containers. 

Check Your Budget 

It is important to check the budget but remember that both containers have different purposes. Cargo containers are best for solid materials, but you need offshore tank containers to transport liquid and gas.
