An improved method and apparatus for supporting and adapting high pressure pumping apparatus for use on or in a marine vessel subject to direct dynamic motions imparted to the marine vessel without damaging the pumping apparatus to thereby extend the useful life of the pumping apparatus. For this purpose the method and apparatus is designed to prevent the deflection of the bearings by providing an axial support and radial damping to vibrations resulting from the motions imparted to the marine vessel. In addition, the pumping shaft is protected when inoperative by preventing the pumping shaft from rotation. Specifically the method and apparatus provide the suction vessel housing the high pressure pumping apparatus to be secured to the marine vessel's deck at all times along with the provision for absorbing the vibrations and stresses due to the marine vessel's movements imparted thereto by being subjected to the direct dynamic motions. The suction vessel for the pumping apparatus is relieved of the stresses at the head plate for the suction vessel by securing the bottom of the pumping apparatus to the suction vessel at all times. The pumping shaft is supported from the bottom of a vertical shaft for axially moving the shaft upwardly to keep the supporting bearing out of deflection so no forces are transmitted to the bearings when the pumping apparatus is non-operational and also prevents the pumping shaft from rotating. |
