STATEMENT OF WORK

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

(CCSFS)

(CLINs 002, and 102)

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

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

(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/CCSFS 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 negative impacts to the Government when delivery times are staggered, and waves are not achieved.

When the Government requires two or more tankers delivered in a wave, the Contractor shall deliver the specified number of tankers for the wave simultaneously to the appropriate delivery location at the specified time.

(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.

(j) Commodity Specification: Hydrogen CGA 5.3-2017, Type II, QVL A

(k) Filter Requirements: A filter with no more than 10 – micrometers nominal and 40 – micrometers absolute rating shall be installed between the manufacturer’s plant system and the manifold used to fill the liquid containers for delivery.

(l) Lot size: Each filled shipping container shall constitute a lot. A minimum of one sample is required per lot.

(m) If conditions warrant, due to mission requirements, drivers may be required to remove and/or secure (turn-off) cell phones, GPS, and other transmitting devices prior to entering the launch complex gates.

(n) SLC-37B and SLC-41 Vent Requirements: The offload configuration utilizes a helium purge through the transfer hose, through tanker off-load circuit and out to the facility vent stack. Local venting at the LH2 tanker is not allowed. Vendor trailer must be capable of venting through the facility vent stack.

(o) Launch Equipment Test Facility (LETF) – Test Support: Testing will require use of vendor supplied LH2 trailer which will interface directly with the test facility and supply LH2 for the duration of test. The interface connection is an Air Force Bayonet. Testing is estimated to last one or two days for each test period, however additional days may be required. Contractor personnel shall be present during all testing and shall be responsible for operating trailer valves which will control test pressure to the facility.

Typical concept of operations are as follows: The LH2 Tanker will usually be on site at 4pm on a Friday, followed by a pre-task meeting with all test personnel to discuss test objectives 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.
