If I were building a new vessel I would build a boat with two engines but one shaft. You can run or both engines. I know a small tug that has that set up.
That covers redundancy but not maneuverability. Even more ideal I think would be diesel / electric drive. 2 shafts, electric motor driven. 2 engines each driving a big generator. So running on 1 engine you have half the power available, but no loss of maneuverability or anything.
