1. A portable, cryogenic fluid pump apparatus with associated instrumentation, conduit legs and accessories in an optimal configuration on a modular supporting platform for plug and play installation at a filling station and on-site inspection and maintenance at the filling station, comprising:
the modular supporting platform comprising a first supporting structure, a second supporting structure and a third supporting structure to define a footprint of no greater than 16 ft2, said second and third supporting structures substantially perpendicular to the first supporting structure, and further wherein said second and said third supporting structures are situated substantially adjacent to each other;
the cryogenic fluid pump apparatus with associated instrumentation, conduit legs and accessories pre-assembled onto the modular supporting platform before deployment to the filling station, wherein the cryogenic fluid pump apparatus with associated instrumentation, conduit legs and accessories are positioned to create the optimal configuration onto the modular supporting platform;
said optimal configuration defined, at least in part, by (i) an unobstructed region to access the cryogenic fluid pump apparatus and associated instrumentation, conduit legs and accessories, said unobstructed region comprising a periphery extending along the modular supporting platform to facilitate the plug and play installation at the filling station and the on-site inspection and the maintenance at the filling station, and (ii) substantial horizontal alignment of one or more of the conduit legs with a corresponding downstream and/or upstream components of the filling station; the cryogenic fluid pump apparatus connected to the first supporting structure and the second supporting structure;
said conduit legs comprising a suction conduit, a return conduit and a discharge conduit each of which is connected to the cryogenic fluid pump apparatus;
said suction conduit extending from a suction port of the cryogenic fluid pump apparatus and adapted to receive cryogenic fluid from a source tank into the cryogenic fluid pump apparatus, said return conduit extending from a return port of the cryogenic fluid pump apparatus and adapted to return the cryogenic fluid from the cryogenic fluid pump apparatus to the source tank to enable recirculation of the cryogenic fluid from the source tank into the suction conduit, the return conduit followed by re-entry into the source tank, said recirculation occurring until a temperature of the return conduit is sufficiently reduced to prevent vaporization of the cryogenic fluid, said suction conduit and said return conduit extending outwards from the modular supporting platform into the unobstructed region and further wherein said suction conduit is configured to be in substantial horizontal alignment with a suction supply valve of the source tank; said discharge conduit extending from a discharge port of the cryogenic fluid pump apparatus along the unobstructed region and thereafter bent downwards so that a portion of the discharge conduit is situated at a lower elevation than each of the suction conduit and the return conduit, and further wherein said discharge conduit terminates as a branched conduit along the first supporting structure; said associated instrumentation and accessories comprising (i) supply instrumentation and accessories connected to the suction conduit, (ii) return instrumentation and accessories connected to the return conduit and (iii) discharge instrumentation and accessories connected to the discharge conduit; and
a controller in electrical communication with one or more components in (i), (ii) or (iii) and the cryogenic fluid pump apparatus to regulate a flow of the cryogenic fluid along the suction conduit, the return conduit and the discharge conduit, said controller located within a control panel connected to the third supporting structure.
