Oil change and filters.....every 20 hours for the first 100 is a good idea.

That would be extremely conservative. They probably changed it after
the sea trials which should be good enough for the trip. No big deal
if they do change it however. I'd bet anything they have an oil
change system that will pump out the old oil into a holding tank and
then pump new oil in from a supply tank. The whole thing can be done
in less than 10 minutes per engine, underway if necessary by shutting
down first one side and then the other.
