-Extract the sims3pack with Delphy's Multipack extractor. Only extract the world you want to install, and extract it to an empty folder.
-When done, go to that folder and sort the packages by date. They will all be named along the lines of 0xa298f199c1344c7e971b53e0f35a64e8.package, but you need the one at the bottom. Usually this is the largest package. This is your world file.
-Rename it. You can name it whatever you want to name it, in this case I named the package Barnacle Bay.world.
-Put the world file in (assuming you installed to the default location) C:\Program Files\The Sims 3\GameData\Shared\NonPackaged\Worlds
-Put the other packages (but not the world file) in Documents\Electronic Arts\The Sims 3\DCBackup
