Trolls are about 30 meters tall on average and can weight anything between 100 tons to 200 tons at sea level. They can only be found to inhabit an island somewhere in the pacific ocean, they are in imminent danger as the volcano is going to erupt at any moment, we must act fast to save them using modern day technology? They can't float let alone swim, they are extremely hostile when approached. We need to get them to safety on another island halfway around the globe where they won't endanger anyone, any solution? I expect zero casualty, short traveling time and no need to break a bank.

Note: the only scientific miracle is the trolls, hurry time is running out!
