Storage Tanks & Pressure Vessels

Essenmotion has extensive knowledge of steel and concrete structure design, fabrication, welding, thermodynamics and the physical properties of gases, fluid flow, heat transfer and chemical engineering. Our tanks are available in many types of shell and insulation systems.

  • Ambient temperature and atmospheric storage tanks
  • Low temperature and cryogenic storage tanks
  • Spherical and cylindrical pressure vessels
  • Above-ground, in-ground and underground tanks
  • Flat bottom tanks, foundations and support structures
  • Internal and external floating roofs and seal systems
  • Prismatic or highly partitioned membrane tanks
  • Single, double and full containment tanks
  • High performance composite concrete and special alloy tanks
  • Pre-tensioned and post-tensioned concrete structures
  • Supported or self-supporting architectures
  • Inert gas blanketing and purging systems
  • Storage condition and containment integrity monitoring systems
  • Surge, sloshing, cool down, rollover and stratification analysis
  • Cryogenic insulation systems (double wall, vacuum, perlite, etc.)
  • Foundation heating and frost heave protection systems
  • Tank/Vessel Protection, Isolation and Insulation Systems

Most tanks we design are constructed of carbon steel and reinforced concrete. We also build tanks using alternative materials such as high performance composite concrete, aluminum, stainless steel, 9% nickel or specialty steels to meet specific customer requirements (such as reactor vessels).

Essenmotion provides engineering and management services for refrigerated low temperature, cryogenic storage tanks and containment systems for the entire range of liquefied gases including butadiene, butane, ammonia, chlorine, propane, propylene, carbon dioxide, LNG, LPG, ethylene, oxygen, argon, nitrogen and hydrogen, as low as -269 °C for liquid helium containment applications.

These containment systems can be designed for different boiling temperatures, vapor pressures and containment configurations. The scope of our refrigerated and cryogenic storage projects typically includes concept definition, design and detail engineering, specification and procurement, inspection and testing, start-up and project management. Our projects have ranged from designing and building individual tanks and refrigerated process systems to entire storage terminals.
