Apparatus facilitating removal of a kort rudder ring on a marine vessel

Image Number 2 for United States Patent #4111148.

This invention is an arrangement for easily removing a kort rudder ring from the hull of an oil drilling rig for examination of the bearings from time to time. The housing of the lower rudder ring pintle bearing is quickly removable from the outside by a diver, so that the ring can be dropped from its upper bearing housing, moved rearwardly, and lifted by lifting tackle to the surface. Thus examination can take place while the rig is still working at sea.
