Patent ID: 8162596

Claim:
A high pressure pumping means for use as a tanker ship or on the tanker ship deck and subject to several degrees of ship movements comprising a U-like housing having a head plate for closing the open end of said U-like housing, a single shaft assembly mounted within said U-like housing and vertically extending between the ends of said housing, said shaft assembly having two ends and mounting a multi-stage high pressure pumping means and electrical driving motor means thereon, said shaft assembly being supported by bearing means adjacent said ends of said shaft assembly and third bearing means between the ends of said pumping means and said drive motor, said U-like housing including a plurality of guide rails mounted inside said housing to permit the pumping means to be removed from said housing by slidably moving on said guide rails and permitting said pumping means to be reinstalled within said housing by slidably moving along said guide rails to assure said pumping means is always located within said housing in the same position, protective means for said U-like housing for securing said housing to the tanker ship deck, said protective means being constructed and defined for absorbing vibrations and stresses due to the ship movements, and means for securing the bottom end of said pumping means to said U-like housing for relieving the stress at said head plate for said housing due to the movements of said tanker ship, and for preventing the pumping means from movements within said U-like housing.
