Cryogenic Control Center & Safe Haven for LOX/LH2 Barges – Stennis Space Center

Construction of a new Cryogenic Control Center and modifications to existing cryogenic process piping systems. The Control Center is being constructed to obtain a LEED Silver rating in accordance with the USGBC rating criteria. The Control Center is constructed of structural precast concrete wall panels with a precast double tee roof substructure, standing seam metal roofing, fixed aluminum windows, concrete and asphalt paving, and associated mechanical/electrical/plumbing systems. The Safe Haven portion of the project includes modifications to the existing cryogenic (liquid hydrogen, liquid oxygen, liquid nitrogen) process piping systems utilized in the manufacture of rocket fuel for testing of rocket engines. The modifications include the addition of vacuum jacketed piping, cryogenic valves, barge transfer systems and a new flare stack.

Description of Specialized Systems:

The process integration piping systems are located within the cryogenic complex and create an extremely volatile environment. The volatility of the systems requires extreme coordination with the facility users to maintain a safe working environment for all employees. The cryogenic piping systems work includes installation of cryogenic valves, vacuum jacketed piping, liquid oxygen piping, liquid nitrogen piping and natural gas piping operating at temperatures extremely harmful if released to the environment. Safety is the top priority while performing work on the systems. The coordination of work efforts is critical to ensure the continued operation of the facility throughout construction and bi-weekly meetings are performed to coordinate work activities with the existing operations to minimize interruptions of service and meet the concerns of the National Aeronautic and Space Administration.
