during chemical cleaning (See Chemical Cleaning Procedure), the unit is subjected to the required initial hydrostatic test of 1-1/2 times the unit design pressure. Depending on insurance requirements, hydrostatic tests following pressure...

on hydrostatic and osmotic forces. Recently, Buishas, Gould and Linninger introduced a third hypothesis namely a computational model that is based on existing empirical data. Their model attempts to combine the two above-mentioned...

reading draughts and comparing with the known hydrostatic properties. The metacentric height (GM), which dominates...from the design, but an accurate value must be determined by an inclining test. The inclining test is usually done...

a hydrostatic release device should the ship begin to sink. A hand pump is provided to "top-off" pressure at night when temperatures drop and internal air pressure decreases. Relief valves are installed in each tube to prevent...
