Propulsion Shaft Bearings - Maintenance & Damage Handling

Half-day training course (online) aimed at reducing risk and improving handling of propulsion shaft bearing damage

Objectives

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

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

Entrance requirements

Basic knowledge of technical vessel operations and shafting systems

Who should attend:
Personnel involved in management of technical operations, maintenance and supervision of drydocking, e.g. technical superintendents, fleet managers, chief engineers involved in management or operation of vessels. Also of interest to technical positions in insurance companies.

Duration: 4 hours


Propulsion shaft bearing damage leads 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 damage can be handled better or even eliminated if all stake holders in the chain have a technically correct and common understanding of some critical factors. This training course focuses on these key factors and includes case studies, a final self-assessment test and summary of key takeaways.

The course focuses on:

  • Practical handling of bearing damage - key steps including managing technical resources
  • Typical bearing damage experienced, detection methods and typical contributing factors
  • Shaft alignment basics, verification methods and compliance scope
  • Single/double sloped aft stern tube bearings, contact area and hydrodynamic lubrication
  • Environmentally Acceptable Lubricant (EALs) performance – impact and mitigation
