Narrative:
After takeoff the 'rud stby upr off' and 'rud stby lwr off' level one alerts illuminated. After running the checklist (aom) we called dispatch/maintenance/md-11 for consultation. I elected to change destinations so as to facilitate repairs before the oceanic crossing. Dispatch gave us a diversion release; we coordinated a new destination with center and we also coordinated approximately 18 minutes of fuel dump with center. Dumping was accomplished on the airway; at cruise altitude of FL290 mach .820 in accordance with the QRH checklist. Dump was secured at 500;000 pounds gross weight. This allowed the aircraft to re-distribute fuel before the approach phase began. We made an uneventful landing where the hydraulic system controller (hsc) was replaced. The flight resumed without further problems.
