Storage Solutions

Cryogenic, high-pressure, underground

We design storage and terminal solutions that do more than contain a chemical compound: they enable it to be received, secured, managed through its process interfaces, and transported to distribution centres, the network or for maritime shipment.

Our integrated EPC approach enables us to manage the entire scope of operations, from unloading to dispatch, by securing the interfaces and drawing on the complementary expertise of VINCI Group entities as required by the project.

Pour le GNL, cela signifie des réservoirs cryogéniques full containment et l’ensemble des infrastructures terminales associées, en import comme en export, avec regazéification lorsque le projet l’exige — hors train de liquéfaction.

For LNG, this means full-containment cryogenic tanks and all associated terminal infrastructure, for both imports and exports, with regasification where the project requires it — excluding the liquefaction train.

Cryogenic tanks (LNG / ethane/ammonia)

Our teams master the design and construction of very large-capacity cryogenic tanks for storing liquefied gases (LNG, ethane, ammonia) at very low temperatures (−163°C for LNG).

We deliver full-containment tanks that combine an inner 9% Ni steel tank with an outer prestressed concrete tank, ensuring high safety and performance.

We also offer vacuum-insulated cylindrical horizontal tanks (vacuum-insulated bullets) for compact cryogenic storage (LH2, LNG, LPG) under pressure (up to 8 bar) with reduced boil-off.

31 LNG tanks built over 20 years
Tanks up to 225,000 m³
Mastery of methods: welding processes, concreting sequences

High-pressure tanks (spheres & bullets – LPG, hydrogen…)

We design and build spherical or cylindrical high-pressure tanks for storing pressurised gases, including LPG, hydrogen, propylene, butadiene, and other industrial gases.

Depending on site constraints, we offer aboveground or mounded configurations to enhance protection.

10,800 m³ spheres (USA)
2,350 m³ mounded bullets (Kuwait – 6 units)
20 spheres of 6,935 m³ (Mexico)

Compliance with international codes and certifications

Shalapa

Underground LPG storage in a salt cavern

Shalapa community, municipality of Ixhuatlán del Sureste, near Coatzacoalcos, Veracruz State, Mexico

Strategic LPG storage in a salt cavern within the Tuzandépetl dome, with dedicated surface facilities for injection, withdrawal, treatment, and product transfer.

Underground caverns

Mass storage

In partnership with our sister company Geostock, a global leader in underground storage, we offer bulk storage solutions in salt or rock caverns.

Reference project – Shalapa (Mexico, 2017)

Entrepose Contracting delivered (EPCC) the surface facilities for the storage of 1.8 million barrels of LPG in a salt cavern at a depth of 1,500 m.
