I’d see dumping over the ocean for 20 minutes single engine (although probably not what the QRH says in a 777 so hands are probably tied there) or just returning and doing the overweight landing (which I HAVE done) and just writing it up for the inspection, after all they are likely going to be changing an engine anyway... the plane isn’t going anywhere.
I don't think you understand at all. If you need to dump it is desirabl, if it can be done, to be at or above 4000AGL, but I don't believe there any regulation that requires any altitude should the need arise. The 777 has a pretty sophisticated fuel dump sytem to cover many of the nuances discussed in this thread so far. in addition there should have been 4 pilots on the flight deck st this point in time.
