METHOD FOR VESSEL'S WEIGHT DETERMINATION Russian patent published in 2012 - IPC B63B9/08 B63B39/00 G01G19/00 

FIELD: transport.

SUBSTANCE: method for vessel's weight determination includes positioning the vessel out of aquatic area and her lifting using lifting facilities, measurement of forces generated by each lifting facility, and subsequent calculation of vessel's weight and longitudinal center of gravity from measured data. In this process, a vessel is placed on keel-blocks in the gaps between which, symmetrically relative to diametral plane of vessel, lifting facilities are laid on building berth. These lifting facilities represent reservoirs made of flexible waterproof material with possibility to supply compressed air into them and to measure internal pressure in each reservoir. In the process of measurement, reservoirs are filled with compressed air until vessel loses contact with keel-blocks. At this moment, internal pressure, area of reservoir contact with vessel's bottom spot and longitudinal center of gravity of contact spot area relative to chosen reference, for instance vessel's midlength section is measured for each reservoir. Then, vessel's weight and longitudinal center of gravity relative to chosen reference is determined by calculations.

EFFECT: higher accuracy of the mentioned vessel's characteristics determination, lower labor consumption and reduction of their determination time.
