We did an at-sea line shaft bearing replacement one time and that had a similar profile as to what Fantasy did. Slowed for a period of time, then up and running. We had to stop and lock the shaft. The bearings are used on support structures within the ship as it reaches from the engines/thrust bearing (load transfer to the hull) to the shaft seal where the shaft penetrates the hull and runs through the strut to the propeller. Maybe it is, and maybe it isn't. It took us about 12 hours to roll the old one out, rig the new one into place then roll the new one into the bearing housing. All this was done at sea with only a temporary slowdown while our shaft was stopped.
Did you remember to feed the shaft seals?
