Low Temperature Storage
McDermott has designed and built refrigerated and cryogenic storage systems for liquefied gases for almost 50 years. During that time, we have delivered nearly 1,000 refrigerated storage tanks and spheres and more than 150 turnkey design-build liquefied gas storage terminals around the globe.
Scope and expertise
The scope of our refrigerated and cryogenic storage projects typically includes concept definition, design and detailed engineering, specification and procurement, shop fabrication, field construction, inspection and testing, startup and project management. Our projects have ranged from designing and building individual tanks and refrigerated process systems to entire storage terminals.
In developing these projects, we draw upon our extensive knowledge of steel structure design, fabrication, welding, thermodynamics and the physical properties of gases, fluid flow, heat transfer and chemical engineering. Tanks and their insulation systems must work together to ensure optimum performance for low temperature and cryogenic storage. Our tanks are available in three types of shell and insulation systems:
- Single-wall steel tanks—this type of tank is used to store products at -60ºF (-51ºC) and warmer. We insulate our single-wall tanks with rigid polyurethane insulation foamed-in-place between the steel shell and an aluminum jacket that serves as both a moisture vapor barrier and provides weather protection. This system offers good resistance to severe weather and fire. Its excellent vapor barrier reduces heat leakage, thus lowering operating costs.
- Double-wall steel tanks—these tanks store products at -28ºF (-33ºC) and colder. Our double-wall steel tanks provide the best possible insulation and offer excellent fire resistance, wind protection and vapor barrier integrity.
- Composite concrete and steel tanks—composite tanks feature concrete outer shells that provide additional protection against damage and offer containment in the unlikely event of tank leakage. Used most often for storing LNG, McDermott can design these tanks with several foundation, shell and containment configurations.
