TVS 2017 Presentation Geislinger GmbH Heavy running

Presentation during the TVS 2017 on Effects of engine and vessel operating conditions on torsional vibration dampers Dr. Klaus Prenninger Geislinger GmbH Learn more Both sea-trials and field reports have proved that vessels do not only operate below the maximum continuous rating MCR propeller curve but they can also continuously operate above it. This happens for example when vessels sail in bad weather conditions in shallow waters due to too small margins in the engine power for the specific ship hull or propeller design or due to special engine torque limiter settings. These conditions can occur over a longer period not just in transient operation. These effects have been summarized in the term Geislinger heavy running. This presentation shows the influence of the Geislinger heavy running power curve as opposed to the propeller curve on the damper selection. This issue is exemplified by discussing the effects on the damper twist and the minimum oil supply pressure required and illustrated by comparing simulated results to measurements.
