Narrative:

In level cruise; I was up receiving my crew meal when we heard a 'boom' sound. Turning around; I saw that the copilot's windshield had completely shattered. Examining it revealed that the outer pane was affected; but the inner pane was still intact. I initiated a speed reduction and a descent; coordinated with ATC. We ran the checklist for a window failure; which basically resulted in turning off the window heat and determining that the remaining pane was structurally sound. We elected to continue our flight at FL230 and below with a maximum speed of 250 KTS. The procedure did not call for this; but I felt it was an appropriate precaution and had minimal effect on our fuel burn for the remainder of the flight. The landing was uneventful; with the exception of limited visibility through the shattered window pane.
