If you’re keen to learn more about these special tanks, read on to get a complete overview of the LNG ISO Tank and its features.

What is an LNG ISO tank?

Generally, an ISO Tank is a tank container that is built according to the ISO standard (International Organisation for Standardization). And are used to transport various liquids and gasses. More specifically, LNG ISO tanks are designed to efficiently carry liquified natural gas (LNG) in bulk.

These tanks are made of stainless steel. Plus they have multi-layered vacuum-insulated pressure tanks, supported by double-walled transport tanks. Hence, allowing them to hold LNG at temperatures of -162 °C (-260 °F). The maximum pressure level of an LNG ISO tank container is 0.690 MPa.

An LNG ISO tank has two containers — an inner tank containing LNG and an outer tank with insulation materials. Full containment tanks are most common and vary in size based on their purpose. Transporting LNG in ISO tanks is an innovative and effective alternative to conventional natural gas distribution.

What Can You Transport In LNG ISO Tank Containers? 

LNG ISO tank containers are intermodal containers used to move liquids, gases, and powders. It is built in accordance with the ISO standards, making it suitable for different modes of transportation. 

LNG tanks are typically constructed with 4 to 6 tanks arranged in a row down the center. The vessel has a double-hull design because two separate ballast tanks, cofferdams, and voids surround the tanks.

LNG or Liquified Natural Gas is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) converted into liquid form for storage or transportation without the use of pressurized vessels or storage. LNG is odorless, colorless, non-toxic, and non-corrosive gas.

The market is full of companies providing LNG ISO tanks at standard rates. xChange helps you to find the right LNG ISO tank container as per your requirements from a pool of verified suppliers.

Know the difference: Types of ISO containers

There are various types of ISO tanks available in the market and each with its own purpose. So how do you know which one is best for your needs?

Don’t worry! Because here’s an overview of the common types of ISO tanks and the type of cargo they’re designed to carry:



Cargo type

Food grade

20ft, 40ft, 45ft

Ideal for shipping/storing food such as beer, milk, and hot chocolate.


20ft, 40ft, 45ft

These are used to transport powders or grains like wheat, oats, and flour.

Swap body

20ft, 23ft, 24ft

An excellent option for when you need more storage space for chemicals. 


20ft, 40ft, 45ft

Perfect for shipping temperature-sensitive liquids, powders, and gasses.


20ft, 40ft, 45ft

Specifically designed to carry industrial, medical, and natural gasses. Examples: liquified petroleum gas and heliox.


20ft, 40ft

Great if you’re looking to transport various types of liquids, powders, and gasses at the same time.

LNG ISO tanks

20ft, 40ft, 45ft

Intended to ship liquified natural gas (LNG) such as methane and ethane.

Let’s now zoom in on the features of the top ISO tank performers:

Food-grade tank container

These tanks are suited to transport temperature-sensitive cargo, such as milk. Its made of stainless steel with mineral wool insulation. As a result, superior thermal insulation maintains temperature for longer. 

Silo tank container

Silo tanks are made of high-grade steel and are known for shipping all sorts of grains and powders. Anything from maize and flour to cement, this is your go-to tank. They’re also coated with a UV-stabilized outer layer to protect the cargo from harsh climate conditions.

Swap body tank container

Swap body tanks are designed to transport hazardous and non-hazardous and food-grade bulk liquid cargo. These tanks allow for the transportation of larger volumes of up to 35,000 liters. Plus, it can hold a maximum cargo temperature of +130°C.

LNG ISO tank container

These tanks have a working pressure ranging from 100psi to 10 Bar and are ideal for the safe trans­port of LNG. LNG tanks also feature high vacuum insulation, stacking capability of 9 units high, a full set of decals, and various pipework options. All these features offer maximum versatility to the end user and operator.

LNG ISO tank types and their specifications

By now we know that LNG ISO tank containers are the most effective vessels to transport liquified natural gases. There are 2 types of LNG ISO tanks commonly used in the shipping industry. These are cryogenic LNG tanks and the standard 20ft and 40ft LNG ISO containers. To optimally serve their purposes, each type and size has its own unique specification.

Let’s dive into each of their specifications and metrics:



Container Specification

(L x B x H /mm)

Loading Capacity

(in L)

Design Temperature


20 ft LNG ISO Container

6058 x 2438 x 2591

22,000 L


40 ft LNG ISO Container

12460 x 2500 x 3980

25,000 L


20 ft Standard Cryogenic LNG ISO 

6058 x 2438 x 2591

20,200 L


LNG can be transported over longer distances using cryogenic ISO tank containers. This allows for a more cost-effective fuel supply to end-users that are further away from LNG supply sources. A 20ft cryogenic LNG ISO container offers a storage capacity of 22,000 liters starting at a 17 BARG working pressure.

Similarly, two 40ft LNG ISO containers can have different specifications, and they can be leveraged for different purposes. For instance, a 40ft cryogenic LNG ISO container provides an exceptional 45,000 liters of capacity with a total payload of up to 36,000 kg. The working pressures for a 40ft LNG ISO standard container range between 10 BARG to 22 BARG with and without pump options.

With specifications out the way, let’s now explore the safety considerations of LNG ISO tank containers.

Safety considerations of LNG ISO tank container

LNG ISO tanks must be handled with extra care since LNG is highly flammable. Here are some key safety pointers to consider when shipping LNG:

  • When handling natural gas, there’s a possibility that gas will permeate clothing, so avoid smoking near the tank, especially while filling and discharging.
  • In case of a leak, remove any ignition sources and cut off the gas supply. Further, shut off the leaky spot and electrical units and have ample ventilation.
  • Another safety tip is to avoid sealing the vessel containing liquefied gas. If left in a sealed state, gas vaporization may result in pressure rise. This pressure rise can cause injury and damage to equipment.
