Faulty Gauges and Sounding pipes. Most of the ballast tank gauges work on pneumatic pressure difference method, where a measured pressure of air and difference of counter-pressure gives the level of ballast in a tank, and the reading is displayed in cargo control room through a digital or analog reading.

The ballast tanks of 65 ships were visited and mud or slime samples were taken for subsequent laboratory analysis. Twenty ships were sampled while in dry- dock, 37 in port, and eight at sea.

unable to verify ballast salinity). Under these circumstances, vessels must conduct an exchange (or flush of empty tanks) resulting in ballast salinity of equal to or greater than 30 parts per thousand. Q: Are there any special management requirements for ‘NOBOB’ vessels or empty ballast tanks? A: For empty tanks to be used for ballasting anddepth, the internal tank pressure in an emergency -.scent can be sufficiently high to stress the light weight ballast tank structure considerably beyond the threshold of yielding.
