No no no.... You do not "install" this engine. You barge it to the dry

Not done that way. The hull is erected and the the engine lifted into the
hull. Then the deck is done.
Hard to replace, anyhow. :-)


Amazing! I can't imagine the cranes that must be needed to lift the
14-Cyl version
of that Wartsila engine, it must be close to 100 feet long and maybe 8
feet wide and 30 tall! Obviously, you have to build the structure that
goes below the engine before the engine goes in, and I assume that the
boat would get scrapped if the engine needed a complete replacement. For
structural reasons, I can't imagine they have a single 100 foot long
hatch over the engine, like a car's hood.

Don't they put them in in sections? They did that with the old steam
engines (which did get quite big): basically erected them in place.
For the Wartsila engine, the crankcase looks to be in sections, & the
cylinders are separate. So the biggest item would be that 300-ton shaft.
But 300 ton is an easy lift for a shipyard crane...
