RFP No. 80AFRC24Q0006 Cryogenic Transportation Trailer March 1, 2024

1.0 Background

The NASA Armstrong Flight Research Center (AFRC) Flight Loads Laboratory (FLL) located in Edwards, CA routinely performs thermal tests that require the use of both liquid and gaseous nitrogen to facilitate cooling of test hardware and purging test chambers. The FLL currently uses a 4000-gallon liquid nitrogen (LN2) trailer capable of delivering LN2 at pressures up to 55 psi.

In the past, the FLL used a LN2 recharger to deliver gaseous nitrogen (GN2) that was capable of delivering temperature controlled GN2 at a volume flow rate of approximately 760 SCFM and a pressure of 100 psi. The LN2 recharger is no longer available to the FLL.

The FLL is looking to procure a Department of Transportation (DOT) approved Mobile Liquid Nitrogen Trailer that combines the capability to deliver both LN2 and GN2. The mobile LN2 trailer shall consist of a self-contained, trailer-mounted unit capable of receiving, storing, transporting, and delivering liquid and gaseous nitrogen. The following statement of work describes the specifications for the system that the government is seeking to purchase.

2.0 Scope

This specification contains the requirements for the procurement of a DOT approved mobile LN2 trailer, for use at Armstrong Flight Research Center. The project scope shall consist of the design, fabrication, testing, inspection, and operator training of the mobile LN2 trailer as a complete unit.

2.1 Work Definition

The contractor shall provide design services, all labor, materials, tools, equipment, transportation, testing, handling, certification, inspection, maintenance and parts manuals, and any other item of expense that may be required for performance of work specified in this specification.

This specification also contains the minimum requirements for the design, manufacture, quality assurance, cleaning, testing, painting, and certification of a mobile LN2 trailer. For purposes of this specification, the Armstrong Flight Research Center is defined as NASA AFRC.

2.2 Work Elements

The work delineated in this specification shall be accomplished as follows below.

2.1.1 New Builds

2.1.1.1 Design

During the design phase the proper equipment configuration to yield the desired LN2 and GN2 flow rates, pressures, and temperatures shall be determined and integrated with an over-the-road trailer. During this phase all proper documentation such as calculations, drawings, test procedures, equipment cut sheets and materials certifications shall be prepared by the Contractor for submittal to NASA AFRC for approval at various time intervals prior to manufacturing.

2.1.1.2 Manufacturing

During the manufacturing phase the required materials and components shall be acquired, fabricated as required and assembled into the final configuration. The unit shall be tested to procedures developed by the Contractor and made available to NASA AFRC for review. Maintenance and operational manuals, and mechanical and electrical drawings shall be completed and delivered with the LN2 trailer.

2.1.2 Existing Builds

NASA AFRC will consider a previously designed and manufactured mobile LN2 trailer that is equal to or less than 30 months old and satisfies the Requirements (Section 3) and the Deliverables (Section 5) as stated in this Statement of Work.

3.0 Requirements

3.1 General

The mobile LN2 trailer shall consist of a self-contained trailer mounted unit capable of receiving and storing liquid nitrogen, transporting the commodity to a given destination over public roads, and then discharging it as liquid at a specified pressure or as a gas warmed to the required discharge temperature and pressure, at the desired flow rate. The necessary cryogenic dewar, pumps (if necessary), high pressure vaporizer, interconnecting piping, control and relief valves, flex hoses, gauges, electrical power and control wiring, and an integrated control console shall be mounted on an over-the-road trailer chassis.

3.2 Fully insulated horizontal LN2 DOT trailer with a minimum capacity of 5,000 gallons, maximum capacity of 6,000 gallons and a maximum allowable working pressure of 250 psig. Tank pressure will be adjustable.

3.3 Ability to deliver LN2 at up to 100 psig to an existing vacuum jacketed 2” LN2 line.

Pressure shall be user adjustable.

3.4 Ability to deliver high-purity GN2 to an existing 2-1/2” plumbing connection at a volume flow rate up to 1000 SCFM and at a pressure of 100 psig (+/-10 psi) and within an output temperature range from -60°F to 80°F. Pressure and volume flow rates shall be user adjustable.

3.5 The following are required to be easily adjustable by end user:

3.5.1 GN2 Volume flow rate

3.5.2 GN2 Pressure

3.5.3 Temperature: -60°F to 80°F (+/-10°F)

3.6 Ability to simultaneously deliver LN2 and GN2 as described in items 3.2 and 3.3.

3.7 The system shall have all the required temperature sensors, pressure gages, liquid level gages and pressure relief devices to allow safe operation of the system for both LN2 and GN2 operations.

3.8 An emergency shutoff system that will safely shut off LN2 and GN2 delivery in the event of an emergency situation and depressurize the system as needed.

3.9 CGA fittings (2-1/2” Nitrogen Connection No. NI-250, Fixed End) shall be used for filling the LN2 trailer and delivering LN2.

3.10 CGA fittings (2-1/2” Nitrogen Connection No. NI-250, Fixed End) shall be used for delivering GN2.

3.11 Local and remote-control operation and monitoring of LN2 and GN2 delivery.

3.12 The pressure vessel shall be ASME Section VIII code stamped and registered with the National Board.

3.13 The process piping shall meet the requirements of ASME B31.3, Process Piping. Other piping shall meet the requirements of the most applicable ASME B31 series Code.

3.14 All system components shall be appropriately marked and labeled.

3.15 One set of supply and delivery hoses and fittings shall be supplied.

3.16 Gauges shall be easily removed and replaced for calibration.

3.17 The system shall be capable of operating in the following environment:

3.17.1 High dust environment.

3.17.2 Temperature ranges from 0°F to 120°F in direct sun.

3.17.3 Maximum sustained wind speeds of 70 mph.

3.18 The mobile trailer shall be DOT approved for transit on public roads while loaded with LN2. Documented compliance with the DOT regulations of 49 CFR 171 – 180 or ASME Section XII is sufficient to meet this requirement.

3.19 The vendor shall be responsible for DOT certification of the mobile LN2 trailer for LN2 and GN2 operations.
