‘Emptying by gravity‘
The vessel’s ballast system is designed and dimensioned to make use of gravity for
emptying and filling the dedicated ballast tanks as much as possible without the use of
pumps. For dedicated ballast tanks this is done through the normal ballast piping.
When filling or emptying the cargohold 3 as ballast water tank, the coal ventilators in the
ends of the weather deck hatch covers should be kept opened as an extra security
against over or under pressurization’ |
