STATEMENT OF WORK

GLENN RESEARCH CENTER (GRC)/ARMSTRONG TEST FACILITY (ATF)

(CLINs 001 and 101)

(a) Delivery: Delivery and acceptance of product will normally be made Monday through Friday, from 6:00 AM to 6:00 PM. However, under unusual circumstances, the Contractor agrees to deliver product 24 hours a day, 7 days a week, including holidays.

(b) Clearance Procedures: The badging point-of-contact will ensure the drivers are issued temporary badges for admission onto GRC. The contractor shall provide upon request complete list of approved drivers for delivery.

(c) Seals: GRC requires the tanker to be sealed to prevent tampering; however, a serialized seal is not required. The Contractor shall maintain contamination‐free and rust‐free cleanliness of shipping container interfaces, transfer hoses and fittings.

(d) Quantification of product delivered: Vendor will utilize certified scales at GRC to determine quantity of product delivered.

(e) Notice for Delivery: GRC will normally place orders by the Thursday of each week preceding the week the delivery is to be made. Under unusual circumstances orders with a minimum of 48 hours’ notice shall be accepted. The total number and frequency of deliveries will be dependent on tanker trailer capacities and ongoing test program needs. The Government will use reasonable efforts to provide 48‐hour notice when modifying delivery orders. The Contractor shall supply a dispatch contact number which can be reached 24/7. Once the delivery order has been set, the Government will contact the dispatch contact number to address any near‐term schedule adjustments.

(f) GRC responsibility during delivery: GRC personnel must be present to operate GRC equipment during the delivery of liquid hydrogen.

(g) Waves of Tankers: There are instances when the Government requires multiple (two or more) tanker trailers delivered at the same time and then off-loaded simultaneously. A group of tanker trailers scheduled for delivery at the same time is referred to as a “wave” of tankers. In these instances, off-loading the wave of tankers simultaneously through a manifold provides significant benefits to the Government. Alternately, there are impacts to the Government when delivery times are staggered, and waves are not achieved. When requested, the Contractor shall deliver the number of specified tankers for the wave at the same time to the appropriate delivery location at the specified time.

(h) Receiving storage: Current facility storage containers in use at GRC include those which are listed below. However, the Government reserves the right to add, withdraw, change, or substitute receiving containers at any time during the life of the contract. Additionally, there will be instances where propellant delivery will be made directly into Government tankers, at either the GRC - Cleveland or ATF - Sandusky.

KENNEDY SPACE CENTER (KSC)/CAPE CANAVERAL SPACE FORCE STATION

(CCSFS)

(CLINs 002, 102, 003, 103, 004, 104, 005 and 105)

(a) Delivery: Delivery and acceptance of product will normally be made Monday through Friday, from 5:00 AM to 3:30 PM. However, under unusual circumstances, the Contractor agrees to deliver product 24 hours a day, 7 days a week, including holidays.

(b) Clearance: All personnel entering KSC/CCAFS must be badged for access in accordance with that described in KSC 52.242-90 (Contract Section 2.2.9).

(c) Seals: KSC/CCSFS requires the tanker to be sealed to prevent tampering; however, a serialized seal is not required.

(d) KSC/CCSFS points of contact will be specified on delivery orders.

(e) Quantification of product delivered: Vendor will utilize certified scales at source plant to determine quantity of product delivered.

(f) KSC/CCAFS responsibility during delivery: KSC/CCSFS personnel must operate receiving equipment during the delivery of liquid hydrogen.

(g) Waves of Tankers: There are instances when the Government requires multiple (two or more) tanker trailers delivered at the same time and then off-loaded simultaneously. A group of tanker trailers scheduled for delivery at the same time is referred to as a “wave” of tankers. In these instances, off-loading the wave of tankers simultaneously through a manifold provides significant benefits to the Government. Alternately, there are impacts to the Government when delivery times are staggered, and waves are not achieved. When requested, the Contractor shall deliver the number of specified tankers for the wave at the same time to the appropriate delivery location at the specified time (applies to all KSC/CCSFS CLINs)

(h) Notice for Delivery: KSC/CCSFS will provide a minimum of 7 calendar days’ notice.

(i) Receiving storage: Current facility storage containers in use at KSC and CCSFS include those which are listed below. However, the Government reserves the right to add, withdraw, change, or substitute receiving containers at any time during the life of the contract.

and procedures along with safety protocols and procedures. The liquid delivery hose and the gas vent (ullage vent) hose will be connected along with grounding of the LH2 Tanker. The hoses will be purged with helium and verified to be less than 1% oxygen prior to initiating LH2 flow. The operation would start with the LH2 Tanker at minimal pressure and begin slow system chill-down for approximately 45 minutes. After chill-down is complete, the tanker ullage pressure will be increased in stages up to a maximum of approximately 50psig.

Test pressures will be adjusted up and down throughout the test. Venting of the ullage pressure during test will be controlled using LETF vent valves. There will be a long duration slow flow that will continue for approximately 4-6 hours. When complete (based on test results or remaining LH2), the tanker operator will vent ullage pressure to less than 5 psig and the tanker will be secured. The flex hoses will then be purged with helium and verified to be less than 1% hydrogen prior to breaking into the system. Hoses will then be disconnected, and the tanker released. The entire operation will typically last 8-10 hours.

There will be approximately 4 NASA and NASA Contractor personnel in the field with the tanker operator, the rest of the test team will be in a control room in the facility. Restroom and snack breaks will be provided. During test operations, there will be a 600-foot control area established throughout the test due to the onsite LH2 quantity/distance requirements.
