Friedrichshafen/Lillestrøm. As a specialist for marine propulsion systems, ZF has introduced an intelligent Condition Monitoring System for thrusters. It monitors the status of the thruster system and thus helps shipyards, shipping companies and fleet operators maintain the safety and efficiency of their ships as well as extend the service life of the propulsion system. In addition to that, a new oil cleaning systems ensures the oil quality and prolongs the oil service life.
The Condition Monitoring System is equipped with various sensors and an intelligent electronic evaluation unit. This system measures vibrations which indicate the condition of the bearings and gears in the thruster's upper and lower gearbox. The measurement results help the operators identify early on which components need to be replaced or maintained. This means repairs can be planned in advance and a worsening in the conditions of the components can be avoided, all of which prevent downtimes and shorten maintenance times. It also extends the service life of the monitored systems and components, allowing the operators to concentrate on their main job.
ZF will be exhibiting at the Nor-Shipping to be held in Lillestrøm, from June 4-7, 2019. Visitors to the exhibition will also have an opportunity to learn more about the oil cleaning system. Peter Toxopeus, Sales Manager at ZF Marine Krimpen B.V., says: “Particularly with biodegradable oil, it is important to keep contaminants, such as water, out of the system so as to prevent downtimes caused by mechanical failures.” By heating up the oil, the water is evaporated, a cotton filter filters out the particles down to 1 µm. Clean oil is pumped back into the system which extends the service life of the oil by 10 to 15 times. In conclusion, fewer oil top-ups are needed which means operators save money.
