rigs & drillships – gearbox

Gearboxes consist of complex gears and bearings with small tolerances that are subjected to high torque when converting slower revolutions to higher or the opposite. Gearboxes are found in top drives, for propulsion etc. and are critical to ensure the rigs and drill ships are operating safe, with high reliability and profitability. 

If the lubrication oil in gears and bearings is not kept free from particles, oxidation residues and water, the systems may fail due to abrasive and fatigue wear, and eventually leading to gearbox or bearing breakdown. Repairing or servicing a gearbox is very costly and will result in downtime.
