Can it be dangerous?
Quite a few times the extraction is extensive. The most dangerous extraction was the Maya Express in Haiti in the 2004 revolution. My problem was I couldn't use any violence against the guards on board — it's not their fault they were hired by the bad guy. In the past, I've been able to bribe them off or trick them off. These guys were selling fuel off the ship to all comers. That night when I came with the tugboat, my fixer said, "There's this guy who wants to buy the fuel on the dock," so they left the ship and I snuck aboard. I'm still a nice guy, so I gave them $300 each.
