From the same shipping forum that Howard quoted from, below is a link with a few thoughts on what might be the reasons for the failure of the engines. It's many years since I set foot in an engine room, but my initial thoughts were fuel problems. However, a few folk relate about issues with the advanced automation on board vessels these days. Is there a parallel with modern cars and the ECU running the show? Finally, there is a post on that thread about the loss of the 2 737Max planes possibly caused by issues with automation.
