AN INSTRUMENT FOR SELECTING THE OPTIMUM LOADING VARIANT OF A SHIP

The Lvov plant Teplokontrol has developed a PV30S1-N instrument for evaluating the correctness of ship cargo loading. An outline of the ships cargo spaces is shown on the instrument panel, and blocks simulating loads are placed in these spaces. The weight load is set in each block by turning the control knob to the proper ton measure. For larger cargo spaces, controls are also provided to correct for longitudinal and vertical displacement of the center of gravity. A type-of- operation switch connects four rheostat units to the indicator. After the ton loads are set in the blocks, these rheostats are adjusted to give a zero reading on the meter. The index markings of the rheostats then indicate the appropriate values: the first rheostat shows the ships dead weight to plus or minus one percent; the second rheostat shows the ships trim to plus or minus 0.2 m; the third shows the sum of the moments about the midship section to plus or minus two percent which indicates the structures buckling or sagging; the fourth shows the total moment about a base line to plus or minus two percent, giving the ships stability. In operational tests, this instrument successfully met all the mechanical and climatic requirements. It is recommended for commercial production.
