THE ACFT ROLLED OVER IN A HIGH X-WIND AFTER LANDING WHILE DEPLANING PASSENGERS. THE ACFT HAD LANDED ON A MOVING BARGE. A LANDING INTO THE WIND WAS BLOCKED BY A CRANE SO THE PLT SIDESLIPPED FROM A FLT PATH THAT PARALLELED THE SHIPS MOVEMENT. THE WIND WAS ACROSS THE BARGE FROM LEFT TO RIGHT. AFTER LANDING THE PLT DID NOT CHANGE THE X-WIND HEADING OF THE ACFT. ACCORDING TO A WITNESS THE ACFT WAS HEADING TOWARD THE RT SIDE OF THE VESSEL & THE WIND WAS FROM THE LEFT. THE PLT LEFT THE ENGS AT 'FLY' BECAUSE HE WAS UNSURE OF THE STABILITY OF THE POSITION BUT HE ALLOWED THE PASSENGERS TO DEPLANE.
