the cruise ship recently lost all 4 engines in a storm and was near to being blown onto the shore. The low lubricating oil detection system cut in as the ship rocked from side to side and the computer controls automatically stopped all 4 engines, presumably to prevent an engine seizure. Passengers had to be air lifted off the ship in terrible conditions by helicopters.
I am a firm believer in two series R.C.D.s in installations. If one fails or is a bit sticky the other should operate and clear a fault. I have personally found several R.C.D.s that were faulty in installations. Relying on just one R.C.D. is taking a bit of a gamble.
