Have you ever taken a closer look at a steam turbine installation on a major vessel? I am a software developer like you, but one of my grandfathers was a ship-building engineer (on large turbine-powered ships in the 30ies and 40ies, to boot), so there is some nerdy knowledge in the family. These installations are extremely intricate, and have to be more or less woven into the fabric of the ship: a modern diesel-electric set-up is plug and play by comparison (apart from the gigantic size of the machinery involved, that is).
I assume that the actual marine engineers in that company tried to tell their managers that this would not work, but that the PR department got to make a press release first. Or something like that.
