Have a 3 door similar to yours. (Fisher & Paykel but same door layout as your Samsung) I have a 2" tie down strap that goes from the top of the fridge down the center (covering the opening of the 2 fridge doors and the bottom freezer door) attaching to a drawer pull under the fridge. Designed it before putting the fridge in place. Mounted the fridge on a platform 2" above the floor so that the drawer pull could be attached to the trim below the fridge. You don't need much to ensure the doors remain closed. I think if I did nothing the doors would remain closed during travel.
