The vessel is equipped with re-loader tanks, one set per system. The re-loader tanks are installed abreast in a row in the centre of the bulk room between the cargo tanks.

The product will be sucked into either one of the two re-loader tanks. Once a re-loader tank has been filled in this way, the re-loader tank will be pressurised by means of air from the convey air compressor. After a pre-set pressure has been reached inside the re-loader tank the pipe line to the storage tank will be opened and the cement will be blown out. 

For the receipt of the air/material mixture and the de-dusting of the suction air a special filter will be installed in the re-loader tank. This re-loader tank will be designed for working pressures between 0,20 and 6,6 bar(a) and will be supplied with a classification society approval certificate. A filter system is fitted in the top of the re-loader tank to separate the material from the suctioned air. This filter system is sized for the maximum capacity of the unit and has a dust emission of less than 5 mg/nm³. 

The dust-laden air is drawn through the filter elements of the filtration system, whereby the dust is captured on the outer surface of the elements. The air passes through the fabric and is released into the atmosphere via the vacuum pumps. For the filters to maintain an optimum condition, each element is regularly cleaned by a reverse jet of compressed air.

The condition of the filter elements is permanently monitored in two ways:

1. The contamination of the cloth is checked by measuring the pressure differences over the filters.
2. Damage or leakage of the filter elements will be detected by means of a dust detection system that is fitted in the pipeline between filters and vacuum pumps.

Remedial action is taken by the central control system in case of an alarm situation. 

For inspection of the filter system there is an manhole fitted on the side of the re-loader tank. The filter elements can be replaced through the side opening. 

All re-loader tanks are equipped with the necessary pressure and level monitoring devices, manholes, etc. The re-loaders will be supplied with frame, piping and valves installed.
