Propulsion shaft bearing damages lead to diminished or total loss of propulsion capability, costly repairs, off-hire time, loss of reputation and increased insurance premium and/or deductibles.

Experience shows that most of damages can be handled better or even eliminated if all stake holders in the chain have a technically correct and common understanding of critical factors.


At the end of the course, the participant will have a better understanding of:

  • Shaft alignment basics, relevance to safe operation and scope of DNV rules and typical industry standards 
  • Typical damages encountered during the operational phase of the vessel and contributing factors
  • Monitoring and maintenance activities aimed to reduce the risk of propulsion shaft bearing damages
  • How to better handle costly and time-consuming propulsion shaft bearing damages (reducing off-hire costs and ensuring a high-quality repair)
