De-scaling ballast tanks with magnesium ribbon offers ship owners and managers a cost effective solution to what can otherwise be a very labour intensive process.
This type of system can be installed very simply by two or three people and does not require staging or shot blasting equipment. The ribbon is light and flexible and is fixed with screw down clamps.
The Process utilises magnesium ribbon, a continuous length of extruded high purity magnesium of rectangular section with a steel wire insert. As a rule of thumb about one metre of magnesium ribbon will be required for every three square metres of surface area within the tank.
The nature of the material combined with the long narrow profile makes it an extremely efficient sacrificial anode when fitted in the appropriate quantities and under full ballast condition. Within a matter of days the potential difference between the tank steelwork and the magnesium will literally lift most of the loose matter and corrosion products such as heavy and light scale, millscale and any loose paint or soft coatings not adhered to the steel work.
MGDuff have been involved in this type of application for over thirty years and offer a complete design and material package. Systems are tailored to suit the individual vessel and combine detailed installation plans with the complete scope of supply including the magnesium ribbon cut to length and ready to fit.
