The machinery is specifically designed for anchor handling operations.

At 4.05 it was entirely underwater and a few seconds later its emergency position-indicating radiobeacon (EPIRB) raised the alarm, which was picked up by the satellite ...
The anchor is shackled to the anchor cable (US anchor chain), the cable passes up through the hawsepipe, through the pawl, over the windlass gypsy (US wildcat) down through the "spurling pipe" to the chain/cable locker under the forecastle (or poop if at the stern (US fantail)) - the anchor bitts are on a bulkhead in the cable locker and the bitter end of the cable is connected to the bitts ...
