Shaft Alignment in Ships | Marine training course

The necessary know-how regarding shaft alignment issues in large cargo vessels


This course which is organized in cooperation with experts from the National Technical University of Athens, Greece, aims to provide with the necessary know-how on the main shaft alignment issues of large cargo vessels. Enroll this course to understand the operating principle of journal bearings and learn how to calculate and apply an efficient shaft alignment plan. Participants will be informed about new in-situ practices for shaft alignment and will practice simple calculations of shaft alignment and bearing performance.
