E-MAIL: Questions concerning Synopsis/Solicitation N00178-00-Q-1000, johnsonse1@nswc.navy.mil. The Naval Surface Warfare Center, Dahlgren Division intends to purchase one (1) 14 ton Liquid Carbon Dioxide Storage Tank with the following specifications: (A) The storage tank shall consist of a welded steel pressure vessel designed and constructed in accordance with Section VIII of the ASME "Code for Unfired Pressure Vessels" for a maximum allowable working pressure of 350 psig. The vessel will be mounted on a wide flanged, steel I-beam skid for optimum load distribution. (B) The storage tank shall be capable of holding 28,000 lbs. of liquid carbon dioxide at 300 psig and 0 F. (C) The tank shall be insulated with a minimum of 4 inches of urethane foam insulation, which shall be covered with a 0.063 factory painted white aluminum shell. The ends are to be covered with aluminum preformed flanged and dished heads. The thermal conductivity (overall U-factor) for the insulated tank wall shall not be greater than 0.03 Btu per hour per square foot per F (assuming a wind speed of 5 mph). (D) The tank shall be complete with a 6" diameter liquid level gauge calibrated to read in pounds, 0 to 600 psig pressure gauge (6" diameter), and all necessary Schedule 80 carbon steel pipe connections for filling and withdrawal of carbon dioxide from the storage tank. (E) A complete refrigeration system shall be provided with the storage tank that will automatically maintain the storage tank at 0 F and 300 psig. The following refrigerants will not be used; R-12 and R-502. The evaporator coil of the refrigeration unit shall be located inside of the top portion of the storage tank, with the compressor and air cooled condensing coil mounted on a frame at the end of the tank. The refrigeration unit shall be equipped with a condensing unit driven by a 2-hp, 230 volt, 3 phase, 60 HZ motor and shall be provided with a motor starter and a 120 volt control voltage transformer. The condensing unit will include a sight glass, refrigerant line, solenoid valve, expansion valve, and refrigeration coil mounted internally in the storage tank. Automatic controls shall be provided to start and stop the unit as required to maintain the proper operating temperature and pressure. (F) The storage tank shall be protected from being subjected to pressures greater than the maximum allowable working pressure by means of two ASME approved relief valves operating in conjunction with a 3-way switching valve. Two bleeder type relief valves operating in conjunction with a Henry 3-way switching valve will also be provided. (G) The tank shall be provided with a pressure switch to sound an alarm automatically in the event of excessive high or low pressure in the tank. The alarm horn and the indicating lights shall be mounted on the refrigeration control panel located on the storage tank. The panel shall be complete with an alarm silence circuit to shut off the audible alarm. Contacts shall be provided for the remote indication of high and low tank pressure alarm. (H) All nozzles on the vessel shall be schedule 80 stainless steel. All other piping and fittings provided as a part of the storage tank system shall be schedule 80 carbon steel, with 2,000 psig rated screwed fittings. Stainless Steel Ball valves shall be provided where the connections are made for the liquid fill to the tank, without emptying the tank. (I) The storage tank refrigeration unit shall be provided with an enclosure at one end, which shall provide weather protection for the valves, electrical and control equipment. The enclosure shall consist of a structural frame, which shall be covered with aluminum sheet, minimum thickness 0.04 inches. The storage tank, enclosure, frame, and other exposed metal surfaces shall be painted according to manufacturer's Standards. (J) Adequate vent area shall be provided to allow cooling air circulation for the refrigeration system. (K) Access to the refrigeration unit shall be provided by a lockable access door. (L) The overall size of the tank should be less than 20' long, less than 10' wide and less than 10' high. (M) Delivery of storage tank will be to the Pumpkin Neck Facility area (route 218), King George, VA 22448 between the hours of 7:00 a.m. 3:30 p.m. Award is to be made under the Simplified Acquisition Procedures.
