Make your way to the ship and work your way through the predator section.
The security console is on the bridge (on the wall between the 2 doors), despite what the waypoint shows so use the remote hacking device to disable it ("cryogenics").
After that make your way down to the outside front left of the ship, on to the ice floe - there's a door back in to the ship in the little cave of ice. Cutscene follows.
Once that ends, make your way to the automatic waypoint and deal with the enemies there. After the fight, open/use the large chest. You'll automatically interrogate the lieutenant after that, unlocking the achievement.
