(57) ABSTRACT
A submersible apparatus for transporting compressed gas comprising a plurality of spools, each having a central bore. A long continuous length of relatively small diameter line pipe for holding compressed natural gas is wound about each spool, so that an inner end of the pipe terminates in the bore while an outer end of the pipe terminates at outer surface of the spool. A tank has a thin housing to store the spools vertically therein, with axis of the bores horizontally to create a continuous pathway therethrough. An inner header extends through the length of the continuous pathway of the bores and has the inner end of the pipes connected thereto. An outer header extends the length of the tank and has the outer ends of the pipes connected thereto. A pair of access ports are provided with each located at one end of the tank to provide loading/unloading nozzles and access ways for maintenance personnel.
