How is this a surprise? The Titanic is ancient. She sailed 108 years ago. There are a lot of bigger engines around than what the Titanic had. The Titanic had two 15,000 horsepower engines and one 16,000 hp steam turbine, 46,000hp combined.
This engine here can do 109,000 horsepower
It’s a 14 cylinder diesel engine that powers the worlds largest container ships and tankers.
