WDB TAXIING TO GATE WHEN WINGTIP HITS GND EQUIP.

Narrative

WE LANDED AT MSP AFTER SHUTTING DOWN THE #1 ENG DUE TO LOSS OF OIL QUANTITY AND PRESSURE. WE REQUESTED THE EMER EQUIP TO FOLLOW US TO THE GATE AND MONITOR THE FAILED ENG WHICH HAD WINDMILLED WITHOUT OIL FOR APPROX 45 MINS. AS WE APCHED GATE; WE STOPPED APPROX 100 YARDS SHORT TO HOLD FOR A GND MARSHALL. AFTER APPROX 3 MINS; A MARSHALL WITH LIGHTED WANDS APPEARED AND DIRECTED US WITH STANDARD TAXI SIGNALS TO TAXI FORWARD. THE MARSHALL WAS STILL TAXIING US FORWARD WHEN WE RECEIVED A CALL OVER THE RADIO FROM EITHER AN ACFT IN THE VICINITY OF NEXT GATE OR THE FIRE TRUCK NEAR THE #1 ENG TO 'STOP! THERE IS EQUIP IN FRONT OF YOUR #1 ENG!' WE STOPPED THE ACFT AT THAT POINT AND WERE ADVISED LATER BY MR. X; A MAINT SUPVR WHO HAD WITNESSED THE ENTIRE EVENT; THAT THE #1 ENG HAD INDEED HIT A PARKED TUG AND THAT THE GND MARSHALL; WHO WAS UNABLE TO SEE THE L WING WALKER DUE TO EQUIP ON THE RAMP THAT OBSCURED HIS VIEW; HAD CONTINUED TO DIRECT US IN NOT KNOWING IF OUR L WING AREA WAS CLR. IT WAS IMPOSSIBLE FOR US IN THE COCKPIT TO SEE THE #1 ENG AREA. WE WERE VERY CLOSE TO THE STOP SPOT; AND THE JETWAY WAS IN POS ON OUR L SIDE.
