Narrative:
Station operation asked the flight crew to reposition aircraft to north ramp due to no availability of gates due to irregular operations. I called the chief pilot and told her what we were doing per SOP. All safety precautions were taken on our part. I was told by operations that other aircraft were going to be parked there. We received clearance by ground control and taxied slowly and carefully. Guide men and wing walkers met us at the north ramp apron area and guided me in. There was a transportation van and an air stair; external power unit was also available there. We were guided in and I taxied very slowly. The guide man signaled me to proceed forward with two lit batons; and the two wing walkers; also with lit batons; cleared me in. I stopped the aircraft on his signal and guidance; and [I] was going to set the brakes when suddenly the aircraft began to move forward on its own. Ahead of us was an airport perimeter metal wire fence and some other large objects on the other side. As the aircraft began to skid faster; with the brakes set and the parking brake set; I had no other tool to use other than reverse thrust. This stopped the aircraft. But; it slid sideways; since there was no traction on the ramp. The aircraft's number two engine hit the external power unit.
