The Danish Defence has acquired a container-based LOX-plant, that is capable of producing liquid oxygen (LOX) for use in C-130J aircraft. LOX is used in the emergency supply-system of the pilots in C-130J aircraft, and therefore is the prerequisite for use of any C-130J aircraft in connection with international operation (INTOPS). The emergency supply-system of LOX must be refilled approximately every 2 (two) weeks, whereby C-130J aircraft must be taken out of any operation during the refill. Currently the Danish Defence does not produce LOX itself, and LOX is therefore purchased from different suppliers. When operating in areas with LOX of a poor quality, aircrafts must be taken out of operations for longer periods in order to find LOX that meets the quality requirements of the Danish Defence. In order to increase the availability of the C-130J aircrafts under INTOPS, the Danish Defence has acquired a container-based LOX-plant in order to be self-sufficient in LOX. The contract includes the delivery of a container-based LOX-plant capable of producing LOX that is compliant with STANAG 7106, 3. e., April 2015 specifications or equivalent. The LOX-plant, including initial spare part packages, initial education and documentation, has been procured on the basis of an acquisition contract. In addition, DALO entered into a sustainment contract (framework agreement) allowing for the subsequent procurement of additional spare parts, education, sustainment services, including maintenance services and support in a period of 84 months from the delivery of the LOX-plant. The 2 contracts should be seen as a whole and has been awarded to the successful tenderer. The contract includes an option for purchase of one additional container-based LOX-plant including initial spare part packages, initial education and documentation and a sustainment contract allowing for the sustainment of the additional container-based LOX-plant for a period of 84 months from delivery of the additional LOX- plant. This option can be exercised within 5 years.
