That I cannot answer. I have no idea what the process is. It may be simple and robust, but I don’t know if they have people manning it during a special sea and anchor detail with a lot of ships. We should ask some of our fellow Freepers who may have had experience with that.
Steering loss at the Helm isn't an uncommon event. I'm not sure about smaller ships but at sea on carriers there is a Steering Gear Machinery Room Watch manned by a Machinist Mate full time underway. Keep in mind he is below deck and not privy as to what is going on topside except for what he is told.
If the steering gear pumps and associated gear are fully operational and it's simply a loss of control between Helm and gear room he can manually operate the rudders when given the degrees from there and keep the ship on course. The orders are either given over the sound powered phone or the squawk box {which ever MC they used}. He can IIRC even steer if electrical power is lost by manual pumps which is much slower for obvious reasons.
We practiced literal loss of steering, loss of the entire Bridge as in destroyed, Loss of Central, and all had back ups which were tested.
