Former marine engineer here. Not really. Usually a tech rep sails with the ship to work out any kinks. In this instance, this isn't something you can work out at sea. A ship I was on had its shafts pulled during a dry dock evolution. When we went out to sea, we discovered that one of the shafts was off-center and moving the line shaft bearing around causing cracks in its foundation. We had to lock that shaft in place and continue underway on just the other shaft. Having to lock the shaft in place isn't a normal occurance, but it is a contingency that is prepared for.
