Our plane was being serviced at Gate X-XX at BWI. All of a sudden; the plane began to shudder and rock. From my seat; the provisioning truck began to lean like it was about to roll on its right side. The Provisioning Agent; a Flight Attendant and the Passenger Agent commented as to what was going on. I stepped into the forward galley. Through the forward service door I observed another carrier's MD-80 'taxiing on the J-line for Gate X-X directly across from our gate. Once the plane was parked; things calmed down.Apparently the jet blast from the MD-80 blasted the entire ramp area surrounding our jet. The ramp to Gate X-X is sloped uphill. If the MD-80 was single engine and/or fully stopped; the brake away thrust required to move the plane up the J-line is what blasted the entire right side ramp area of my jet. My major concern was for ramp and fueling personnel's safety. I called Ground Control to advise that the jet that just taxied in to Gate X-X almost flipped our provisioning truck over. He immediately said the area was uncontrolled and not his responsibility. Why is a push call and communications with Ground required at all times in the alleyway if uncontrolled? He said he could call State Personnel. I said the company would get it addressed. Called the Chief Pilot on Call and advised him of what just happened. Advised him I would be filing a report in order that Company Safety could get this unsafe condition addressed.
A Medium Large Transport aircraft and a service vehicle; parked at a gate in BWI; were dramatically rocked by jet blast from an MD-80 powering up to enter an uphill approach to another gate.
