1. DESCRIPTION OF REQUIREMENT: Defense Logistics Agency Energy (DLA Energy), as the Department of Defense (DoD) Integrated Materiel Manager (IMM) for Aerospace Energy products and services, requires the refurbishment, recertification, maintenance and disposal preparation of a fleet of compressed gas tube-bank trailers, International Organization for Standardization (ISO) containers on chassis and stand-alone chassis, which are utilized for bulk compressed gas service. The Contractor shall provide all supplies, products, management, tools, equipment, and labor necessary to ensure that container fleet is brought to and or maintained to a safe, serviceable and roadworthy condition and that any equipment deemed unserviceable by DLA Energy is properly prepared and readied for disposal. Compressed gas Tube-Bank Trailers, ISO Trailers and chassis, will be referred to hereafter as equipment.

2. SCOPE: The Contractor shall inspect, refurbish, recertify and provide necessary maintenance or repair services for equipment owned by DLA Energy. Some equipment will need to be prepped for disposal. The Contractor shall be able to store equipment while awaiting service and after service is complete while it is pending transportation for filling or for disposal.

3. INSPECTIONS: The Contractor shall inspect each piece of equipment when it is delivered to Contractor’s facility to determine scope of work needed to bring or keep equipment serviceable and in roadworthy condition as required by the Department of Transportation (DOT). The Contractor shall perform the following inspection services:

3.1 Incoming Equipment Inspection: The Contractor shall inspect each piece of equipment IAW 49 CFR § 396 within 24 hours of equipment arriving at Contractors facility by utilizing the attached government DD Form 626, “Motor Vehicle Inspection (Transporting Hazardous Materials)” or equivalent to document the condition of the equipment. Equipment inspection reports shall be submitted to the DLA Energy Customer Account Specialist/Transportation Specialist (CAS) by equipment serial number via email within three days of report.

3.2 Maintenance Inspection: within fourteen working days or as otherwise specified on the assigned Delivery Order (DO) issued by the Contracting Officer (CO), the Contractor shall inspect equipment and submit to the CO a detailed list of repairs required to return the equipment to usable, serviceable and roadworthy condition. In addition to this detailed list, the Contractor shall also include digital photographs of equipment indicating the Contractor’s proposed repairs. The Contractor shall be responsible for visually inspecting all mechanical, electrical, pneumatic and structural components for damage, wear, distortion, missing parts, or other forms of failure or potential failure. The Government reserves the right to have a Government Representative inspect the equipment relative to the repairs proposed by the Contractor, prior to approval/acceptance of the Contractor’s proposal. The CO will advise the Contractor of approved repairs. The Maintenance Inspection will be the document used to track work required and approved, and will include, but not limited to, items listed in paragraphs below titled “Recertification” and “Maintenance and Refurbishment”.

3.3 The Contractor shall provide a qualified inspector that meets the requirements of 49 CFR § 396.19 and 49 CFR § 396.25. The Contractor shall perform an Annual Inspection of chassis IAW CFR § 396.21 and Appendix G to Subchapter B – “Minimum periodic inspection standards” when annual chassis inspection is expired or within one month of expiration. The Contractor shall provide a copy of the annual report to the DLA Energy CAS via email within three days of report.

4. RECERTIFICATION: Cylinders shall be recertified by an approved DOT testing method. If applicable the Contractor shall submit a copy of their DOT special permit showing the method by which the cylinder will be tested. Cylinders shall be recertified IAW all applicable regulations and requirements. The following requirements shall apply regardless of which type of testing method is used.

4.1.2 All gaseous nitrogen used during the recertification process shall meet the requirements of MILPRF27401G, Type I, Grade A, 07 Aug 2013.

4.2 REQUIREMENTS: The following requirements shall apply regardless of which type of testing method is used.

4.2.1 The Contractor shall be a DOT certified testing facility.

4.2.2 The Contractor shall assure all records clearly identify corresponding cylinder number and equipment number. Provide a tube diagram for each piece of equipment indicating pass or fail.

4.2.3 The Contractor shall provide a continuous chart recording of pressure and time for each cylinder hydrostaticly tested.

4.2.4 When disassembly/reassembly is required, the Contractor shall document the location of cylinders on the equipment by serial number, location and equipment license number.

4.2.5 Testing of the cylinders to the required pressure by DOT and testing of the manifolds to the required pressure IAW American Society of Mechanical Engineers (ASME) Code for Pressure Piping, B31 shall be performed. Clean/filtered water shall be used for hydrostatic testing to prevent contamination of cylinders and manifolds.

4.2.6 The Contractor shall replace all burst discs in the manifold. Rupture disc heads shall be installed with a minimum torque of 40 ft-lbs.

4.2.7 After approved DOT testing method and cylinder assembly, all internal surfaces that will be in contact with the product shall be rinsed with water which meets the requirements of ASTM D 1193, Type IV or equivalent and then purged with dry, filtered nitrogen until the exiting gas reaches a maximum dew point of -80°F. Other methods to ensure cylinders are clean and dry after testing may be acceptable with prior approval of the Contracting Officer (CO).

4.2.8 The cylinders shall be filled with a helium/nitrogen gas mixture of at least 5% helium/95% Nitrogen for system leak testing. The fully assembled gas system (cylinders, valves, manifolds and safety devices) shall be pressurized to the maximum allowable working pressure with the gas mixture. All threaded joints and other potential source of leaks shall be leakchecked using a leak detector common to the industry. The Contractor shall repair all leaks and demonstrate the absence of leaks in the trailer assembly for a minimum period of 24 hours, at the maximum allowable working pressure.

4.2.9 Once the gas system has been determined to be leak free, the Contractor shall bleed down the helium/nitrogen pressure to 15-20 psig @ 70F or purge the helium/nitrogen mixture from the cylinders and replace with either helium or nitrogen blanket at 15-20 psig @ 70F. The 15-20 psig inert blanket shall be maintained on the cylinders to prevent contamination.

4.2.10 Prior to the Government inspection and final acceptance, the Contractor shall perform the following for equipment requiring recertification testing only.

4.2.10.4 Should the Contractor discover any additional repair(s), as a result of the above inspection, the CO shall be notified in order that the cost of these repair(s) shall be included in the SERVICES-MAINTENANCE AND REFURBISHMENT contract line item.

4.2.10.5 All materials and components used as replacement material/components shall be compatible with the intended service and equivalent in design to the original. If original part “equivalency” requires the use of outdated technology, the Contractor shall propose to the CO to use replacement parts that are of newer technology. Prior approval by the CO is required before newer components are installed.

4.2.10.6 If any cylinder fails to comply with the testing requirements as specified herein, the Contractor shall provide the CO with a detailed description stating the reasons for cylinder failure and include costs to repair or replace the cylinder. All removed parts and/or hardware shall be retained until offered to the Government for inspection. The CO will review and provide preapproval to the Contractor to repair or replace the parts. The Government will make the determination of which removed components will be disposed of by the Contractor and which will be sent to DLA Disposition Services.
