LNG Tanks

For more than half a century, McDermott has focused on providing superior solutions for liquefied natural gas (LNG) storage. Our projects comprise more than 200 LNG storage tanks throughout the world, including the world's first double-wall storage and full-containment tanks.

We provide comprehensive design-build services for LNG storage tanks and LNG facilities. We deliver projects on a lump sum, turnkey basis, using our own resources to provide engineering, conceptual design, detailed design, facility optimization, project planning and management, procurement, fabrication, construction, commissioning and operator training. 

A smart way to do business

Our true EPC business model translates into reduced total cost of ownership for our customers. This approach also enables us to shorten project schedules, minimize the customer's risk and maintain rigorous quality control through every step of the project. We provide single-point responsibility so our customers do not have to worry about delays, inefficiencies and duplication of effort that can occur when multiple contractors are involved. 

For every LNG storage project, we carefully evaluate the customer's requirements and recommend the solution that provides the greatest long-term value. Our team of experienced civil, structural and construction engineers strives to optimize the entire storage tank project rather than focusing on a particular component. 

Global, yet local

With offices worldwide, we have the resources to design and build LNG storage tanks in any location and under all types of logistical constraints. Our people have the localized knowledge to provide front-end permitting and regulatory compliance support all the way through startup. We direct-hire and train local field personnel whenever possible, and we can quickly mobilize large erection crews anywhere they are needed. 

Our unique business model, integrated resources and global presence translate into low-risk, high-value LNG storage solutions for our customers. We provide a variety of LNG storage options, including: 

  • Single-containment tanks—our single-containment tanks typically feature a primary liquid containment open-top inner tank, a carbon steel primary vapor containment outer tank and an earthen dike for secondary liquid containment. 
  • Full-containment tanks—full-containment tanks typically feature a primary liquid containment open-top inner tank and a concrete outer tank. The outer tank provides primary vapor containment and secondary liquid containment. In the unlikely event of a leak, the outer tank contains the liquid and provides controlled release of the vapor.
