LNG Vaporization Plant
Connecticut
SA provided structural engineering services for design and replacement of this federally-regulated LNG vaporization system.
Stephens Associates Consulting Engineers (SA) structurally designed foundations and equipment supports for Liquefied Natural Gas (LNG) vaporization upgrades at this existing facility to meet heating system demands.
SA structurallay designed concrete pedestal supports for two new LNG vaporizers, cast-in-place concrete retaining walls and a sub-impoundment for spill containment, a precast concrete elevated spill trench, and foundations for a pre-fabricated metal-framed building, 11,000-gallon water-bath heaters, and 14,500-gallon water/glycol tank.
SA designed the concrete structures to resist severe loading from wind, earthquake, and temperature fluctuations from LNG exposure. The design conformed to Federal Energy Regulatory Commission (FERC) criteria, and SA responded to FERC- and peer-review during design and permitting.
During construction, SA coordinated Code-required Special Inspections as the Registered Design Professional for structural components we designed, responded to structural-related submittals and Requests for Information (RFIs), and periodically performed on-site Special Inspections of soil subgrades prior to foundation construction.
