LNG Systems

BSHE will do Engineering, development and manufacture of tanks for the storage of liquefied natural gas LNG and other liquefied gases at cryogenic pressure and temperature. Our technical team for the development and manufacture of tanks for the storage of liquefied natural gas (LNG) and other cryogenic storage gases, collaborates closely with our clients in the design and definition of the products before their manufacture and supply, adapting them to the needs of the project. Our main clients include the most important multinational energy companies, the most prestigious engineering companies and the best professionals in the sector in all international markets, who have BLUE SEA HEAVY ENGINEERING products for all types of projects related to LNG.

Static Tanks for LNG Storage

Static tanks for LNG storage in horizontal or vertical installation up to 320 mcapacity, according to European Directive 2014/68/CE and with CE marking. Upon request, according to ASME VIII div.1 and with ASME marking, or adapted to the regulatory requirements and specific requirements of the place or country of destination.



The LNG tank pressure limit is that which the tank is designed for. This value can be found on the mandatory nameplate of each equipment.

The only mandatory guideline in the manufacture of storage tanks is the European Pressure Equipment Directive (PED 2014/68/EU). The choice of the standard or code for its design and manufacture is the responsibility of the manufacturer. For all LNG equipment that is installed in Spain, the indications of the Spanish regulations on LNG facilities must be observed.

Each fluid has particular characteristics that must be taken into account. In some cases, it will not be possible to store another fluid, or restrictions on the degree of filling must be taken into account. In other cases, it will be possible by making slight changes to the level measurement system.

According to Spanish regulations, a vacuum check is enough (it must be less than 0.6 mbar).

Although the only mandatory inspections are those indicated in the Gas Regulations and the Pressure Equipment Regulations, it is advisable to establish a shorter periodicity to carry out this check. Each maintenance company must mark a maximum period, according to their maintenance plan.

It is a circuit by which fluid is sent in the gas phase to the consumption pipe (normally the liquid phase). In this way, a rapid decrease in pressure in the tank is achieved, which can prevent the opening of safety valves. If there is no consumption, the economizer cannot perform its function.

There is no pre-established criterion. It is recommended to create vacuum (= reduce pressure) before reaching the value of 0.6 mbar
