Abstract
The weight of a vessel having trunnion shafts supported by bearings fitted with pressure pads is determined as a function of the fluid pressure necessary to raise the shafts a constant distance and maintain the distance constant.
Claims9
A method for measuring the weight of a vessel having shafts journaled in bearings fitted with fluid-actuated pressure pads acting on said shafts, wherein the improvement in said method comprises:
- a. pressurizing said pads whereby said shafts raise a distance above said bearings;
- b. measuring the resulting vertical distance of said shafts;
- c. controlling the pressure on said pads so that said vertical lift distance is constant;
- and
- d. measuring the weight of the vessel as a function of the pressure applied to said source of supply.

A method for measuring the weight of a vessel having shafts journaled in bearings fitted with fluid-actuated pressure pads acting on said shafts, wherein the improvement in said method comprises:
- a. flowing fluid from a pressurized source of supply to said pads whereby said shafts raise a distance above said bearings;
- b. measuring said distance;
- c. collecting excess fluid exuding from said pads;
- d. flowing said excess fluid to a reservoir;
- e. pumping said excess fluid into said source of supply;
- f. maintaining a controlled pressure on said source of supply and fluid acting on said pads whereby said distance is constant;
- and
- g. measuring the weight of said vessel as a function of said pressure applied to said source of supply.
