ABSTRACT:
A bearing assembly comprises one side exposed to a fluid and the other side to a dry area or compartment(s) which can be emptied. To replace part(s) of the bearing assembly a compartment is located in the compartment(s) through which a section of the bearing is guided. After a part of the bearing section has been moved backwards the compartment can be closed via a valve, then the bearing section can be removed completely from the cavity thus preventing considerable quantities of fluid from entering the compartment(s). This bearing structure can be used in a vessel turret assembly.
