Shaft Grounding is essential.
BAC Corrosion Control A/S supplies systems to marked leading companies.
Let us help you protect your investment!
When the propeller shaft is rotating, it will be electrically insulated from the hull by the lubricating oil film in the bearings and because of dissimilar materials used for the propeller (bronze) and the hull (steel) they will form a galvanic couple where the hull is the most active part.
The current generated on the rotating propeller surface and possible from the hulls ICCP system will enter the shaft and try to return to the hull.
If the shaft is not grounded, the current will pass from the shaft through the bearings when the oil film breaks or through a droplet of seawater in the lubricating oil coursing pitting of the shaft bearings or other parts of the machinery.
In order to prevent galvanic or spark corrosion on the shaft bearings, we produces a shaft earthing device, which is well proven and easy to install. The BAC shaft grounding system comes in 5 standard versions.
BAC Corrosion Control A/S delivers all standard spare parts with short notice and a range of other type of silver graphite brushes.
