Thanks for the additional information.
I think this application is the new catamaran high speed ferry being designed and built by Incat in Tasmania. The LM2500 engines and their accompanied waterjets are separately located in each hull. So I can understand the logic to automatically shut down an engine to save it. I would imagine each set operates independently of the other and there is no common gearbox. The duel fuel concept is very unique.
