Mines can be laid in many ways: by purpose-built minelayers, refitted ships, submarines, or aircraft—and even by dropping them into a harbour by hand.

The shore cable from the underwater distribution box of each mine group ran back to a cable hut on the shore near the mine casemate, and from there to the casemate itself, where it was connected to a mine control panel (see photo at left).
