WebThis oil electrically insulates the propeller from the hull structure and because of the propeller's dissimilar materials, Eddie currents are generated due to the galvanic cell, causing a static build-up. If the shaft is not earthed the static will eventually discharge by arcing across the lubrication oil known as 'spark corrosion'. http://www.mcpsltd.com/shaftearthing.html
WebSystem for Propeller Shaft Earthing A turning propeller-shaft on a ship becomes electrically insulated from the hull by the lubricating oil film in the metal bearings or through the use of non-metallic bearings materials. It is absolutely necessary to ground the ship's propeller shaft to the hull. WebThis is because turning propeller shafts are electrically insulated from the hull by the lubricating oil film in the bearings and by the use of non-metallic bearing materials in the tail shaft. The problem can be eliminated if the shaft is …
