The Penfeld, within the military enclosure, is almost wholly lined with quays, but ships cannot come directly alongside these quays because of heads of rock that are left exposed at low tide. That's why floating stages are moored fore and aft, mainly on the left bank, to make up postes where some “small” ships can come alongside and use some installations such as the large crane.

Little used upstream of the Pont de Recouvrance, downstream of this bridge these postes nevertheless serve the old sailing ships of the Navy, the tugboats and other support boats of the arsenal, and transrades, passenger ships which provide a service across the roadstead (rade de Brest) between Brest and the Crozon peninsula (Île Longue, École Navale)

These two quays are located between Bassin 9 and the groyne of Laninon. They are serviced by five cranes. The latest major overhaul dates back to the reconstruction of the basins of Laninon, whose lengthening has altered the layout of the oblique quay.

These quays are used for the pre-launch finishing of the new ships built in Brest (Like French ship Mistral and French ship Tonnerre), the mooring of the larger naval assets of the Marine Nationale (Like French cruiser Jeanne d'Arc), and the floating maintenance of all types of Vessels
