Regasification terminal & cryogenic tanks

Our engineering teams have developed cryogenic tank designs that meet the strictest requirements and achieve superior construction outcomes. By optimizing structural calculations, materials, and boil-off gas management, we provide tanks that are robust, safe, and efficient over decades of operation. This proprietary know-how has been applied in landmark projects such as BBG and Gate Terminal, giving Sener a unique position in the global LNG market

Why choose us 

Our track record includes benchmark references that highlight both scale and innovation. At Gate Terminal in Rotterdam, one of Europe’s largest LNG projects, we participated in major expansions that included the construction of a 180,000 m³ tank and additional throughput capacity. In Spain, the BBG expansion saw our engineers design, procure, construct, and start up a 150,000 m³ tank—the first in the country to comply with EN 1473 and EN 14620 European standards. At the German LNG project in Brunsbüttel, we are responsible for delivering two 165,000 m³ tanks as part of a strategic terminal with a planned capacity of 8 BCMA. These references show our capacity to combine large EPC scopes with proprietary innovations that set new benchmarks for safety and efficiency.

How we work 

We manage the full lifecycle of LNG infrastructure. In assessment, we study demand, marine conditions, regulatory requirements, and opportunities for fuel transition. In design, we apply advanced modeling and our own gas engineering services to optimize cryogenic tanks, vaporisers, compressor layouts, and jetties. Implementation is carried out under EPC contracts that integrate civil, process, marine, and electrical scopes with rigorous QA/QC. Finally, in operation, we support clients with predictive maintenance, boil-off gas reliquefaction, and upgrades that ensure assets are hydrogen-ready and future-proof.

We ensure safety and efficiency from design to long-term operation

From the early design phase, we embed safety, durability, and adaptability into every cryogenic storage tank and terminal. Our lifecycle services ensure that assets remain compliant with tightening environmental standards and resilient against evolving energy demands. This combination of EPC excellence and proprietary engineering makes Sener a trusted partner for critical LNG infrastructure.
