Synopsis for A-3 Test Stand Test Cell and Diffuser Fabrication and Installation Package
The NASA/SSC Acquisition Management Office plans to issue a Best Value Request for Proposal for a single award four (4) year Indefinite Delivery Indefinite Quantity (IDIQ) contract. Specific projects will be defined in each of the subsequently issued delivery orders. The project shall consist of A-3 Test Stand, Test Cell and Diffuser Fabrication and Installation Package to be delivered to and installed at the John C. Stennis Space Center, Mississippi. The work for this requirement consists of, but is not limited, to the following: providing labor, equipment, and materials to fabricate and install a Test Cell, Diffuser and associated systems as defined in the available Specification as well as required modifications to existing facilities. The effort includes fabrication, inspection, testing, delivery, and installation at Stennis Space Center Test Stand A-3 a complete Test Cell and Diffuser. The Test Cell and diffuser will be used to produce a vacuum condition for the testing of a rocket engine to be contained within the Test Cell. Included in this procurement are all cooling water pipes and connections to the test cell and diffuser, all steam piping from the Chemical Steam Generators to the Steam Jet Air Ejectors, the Steam Jet Air Ejectors, and all access hatches to the test cell. Support structure and support infrastructure will be required as needed to complete the system installation and make it functional and modifications to existing facilities may be required. This may include facility infrastructure, electrical systems, and instrumentation and control elements. The Test Cell and Diffuser and all associated pipe will be fabricated, cleaned, installed, and tested per the requirements identified in the specifications noted in the resulting solicitation.
The new test cell equipment for the A-3 Test Stand shall consist of a carbon steel stiffened cylindrical pressure vessel of approximately 40 feet in diameter and 54 feet tall with a hemispherical head on top and an inverted conical head on the bottom. Penetrations of the vessel include twenty-two (22) feet by Sixteen (16) feet opening for a main door, four personnel doors, and numerous nozzle penetrations. The inverted conical head contains a seventeen (17) feet diameter opening to which the diffuser capture duct is connected. The vessel is designed for one atmosphere external pressure and two atmospheres internal guage pressure. The vessel will be fabricated and installed in conformance to the ASME B&PV Code Section VIII Division 1; no code stamp is required. Internal to the test cell are two levels of platforms and a Thrust Take Out Structure (TTOS) to which a Government Furnished Equipment (GFE) thrust measurement system (TMS) is connected. The estimated weight of the TTOS and TMS is 305,000 pounds (200,000 lbs TTOS, 105,000 lbs TMS). Contractor shall install (i.e. bolt the main components on to the underside of the structure) the GFE thrust measurement system. The engineers estimated weight of the test cell equipment is 900,000 (excludes weight of the TMS) pounds. The test cell is to be installed on top of a GFE structural steel tower at approximately 190 feet above grade. Additionally, the contractor shall be responsible for setting two (2) insulated cryogenic vessels (run tanks) on top of the stand and the diffuser and associated duct contained within the stand. One vessel, Liquid Hydrogen (LH2) is approximately thirteen (13) feet diameter and one-hundred twenty (120) feet tall. One vessel, Liquid Oxygen (LO2) is approximately thirteen (13) feet diameter and fifty (50) feet tall. Both vessels are to be set in place and anchored to the structural steel tower at approximately elevation two-hundred (200) feet above grade. The estimated weight of each vessel (run tank) is 250,000 pounds. The diffuser is a water-jacketed cylindrical duct that varies from seventeen (17) feet two (2) inches diameter to eleven (11) feet six (6) inches in diameter over a length of three-hundred six (306) feet. The duct consists of a one-hundred sixteen (116) feet vertical segment, thirty three (33) feet three (3) inches radius elbow, and a one-hundred thirty eight (138) feet horizontal segment.
The order of magnitude for the procurement is greater than $10,000,000.00 and the effort shall be completed within five-hundred forty (540) days after receipt of notice to proceed.
