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.
