How to launch Origin in offline mode.

Tomorrow, me, my dad, and my sister are going on a camping trip in Wisconsin and while were driving I want to be able to play the battlefield 4 campaign.  I don't want to keep my computer on all the time so I'm probably going to shut it down during like mid driving and such and turn it back on later.  I've set origin to offline mode but it only works if I first have an internet connection to first open origin.  Is there a way I can open origin without having an internet connection.  Even if thats not possible, is there anyway to open battlefield 4 campaign then without battlelog?? Thanks for the replies 🙂
