Install Liquid Nitrogen at LC39B

NASA’s John F. Kennedy Space Center (KSC) has played a pivotal role in NASA’s missions, having been the departure site for the first human journey to the moon; the starting point for hundreds of scientific, commercial, and applications spacecraft; and as the base for Space Shuttle launch and landing operations.  It is now the base for NASA’s Artemis Program and multiple private ventures such as the SpaceX and Blue Origin programs.

In 2024 NASA awarded a contract to Advon Corporation to provide utilities and infrastructure to support the installation of a LN2 skid provided as Government Furnished Equipment.  The skid will use LN2 to cool ambient temperature gaseous helium (GHe) to cryogenic temperatures.  This design shall include all associated infrastructure, subsystems, and appurtenances required for skid operation and the delivery of cryogenic GHe from the skid to the Mobile Launcher 2 (ML2).

Scope: The work to be performed under this Contract consisted of providing the labor, materials, and equipment to demolish an existing concrete slab, prepare the site, pour new tank foundations and replaced the previously demolished slab. The mechanical scope includes the installation of AL6XN stainless steel tubing and 316 stainless steel fitting and the required accessories for new GN2 and GHe lines. New Vacuum Jacketed 316 stainless steel lines, fittings and accessories shall be provided for the transmission of Cold Gaseous Helium (CGHe). The project scope also includes the supply and installation of non-potable water (NPW) lines. The electrical scope includes the supply and installation of underground conduit, exposed conduit, cable trays, wire and associated breakers, switchgear, pull boxes, etc. for the transmission of power from an existing building to the new LN2 Skid. In addition, a large quantity of conduit will be installed for the installation of communications cables by other. The balance of the project scope includes demolition, the fabrication and installation of structural and miscellaneous metals, an extensive engineered system of pipe supports, high performance coatings, modifications to the fire alarm systems, pavement markings and sod.
