What statement is true concerning the arrangement of line shaft bearing housings?

Correct Answer: Option A — Line shaft bearing housings are typically split half pedestal type bearing housings.

Line shaft bearings support the propeller shafting and are designed as split-half pedestal housings to facilitate maintenance. This configuration allows the top half of the housing and bearing shell to be removed for inspection or replacement without requiring the removal of the entire heavy shafting string from the vessel.
