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 "
http://www.youtube.com/watch?v=05_ahAulMSE .

Maybe not, just checked the engine weight again and both cranes together
can only lift 2/3 or the specified engine weight.
