Safety and Regulation


Natural gas is nothing new. It has been transported for decades, and new technologies make continuous growth possible.

The LNG industry's highest priority has always been safety and security, which is reflected in the industry's enviable safety record. LNG is not stored under pressure and it is not explosive. Although a large amount of energy is stored in LNG, it cannot be released rapidly enough if released into the open environment to cause the overpressures associated with an explosion. LNG vapors (methane) mixed with air are not explosive in an unconfined environment. A major incident resulting in a large release of LNG could result in a fire, but only if there is the right concentration of LNG vapor in the air (5% – 15%) and a source of ignition.

Ship Safety

More than 135,000 LNG carrier voyages have taken place without major accidents or safety or security problems, either in port or at sea. (The International Group of Liquefied Natural Gas Importers (GIIGNL) – 2011).

LNG ships are double-hulled, with more than six feet of void space or water ballast between the outer and inner hulls and the cargo tanks.  The double hulls help to prevent leakage or rupture in the event of an accident. LNG ships are also equipped with sophisticated leak detection technology, emergency shutdown systems, advanced radar and positioning systems, and numerous other technologies designed to ensure the safe and secure transport of LNG.

Terminal Safety

LNG import and export terminals are designed with multiple layers of protection and must meet rigorous safety regulations. They are equipped with spill containment systems, fire protection systems, multiple gas, flame, smoke and low- and high-temperature detectors and alarms, automatic and manual shut-down systems, video surveillance systems, and highly trained personnel.


The storage of LNG in safe cryogenic tanks and to use it as a fuel is already regulated by European standards such as:

  • EN 13645
  • EN 13458

With its high experience in flammable gas, Prima LNG and the different Business Units of SHV group have developed a standard for LNG satellite plants in order to comply with these regulations, but also to set a high level of safety.

Local regulations, when existing, are also taken into account. Prima LNG can also assist you to get the local approval from authorities, if needed.

Technical standards

As part of its expertise, Prima LNG has developed a European standard for LNG satellite plants - based on the Europeans norms and standards and with a specific focus on the following points:

  • Safety first
  • Low methane emission concept
  • Easy usage for the end customer

Prima LNG and the different Business Units of the SHV group worked with third party specialists in order to challenge this design and to launch this activity in the most sustainable way possible.
