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

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.

Maybe the sort of gantry crane at Harland & Wolff in Belfast, 840 tonnes
each apparently. Best not to watch the crane accident video or "how to
take out an upstart tower crane "
