Norfolk Z-Loop Repair Project Completion Report

摘要

The process of deperming submarines requires subjecting the ship to a vertical magnetic field. The field is generated by a so-called Z-loop, a coil of wire wound in a horizontal plane surrounding the ship. At the Lamberts Point Deperming Facility, the Z-loop consits of two sections, one located under the decks of the catwalks forming the sides of the deperming slip and another directly under the first at a depth of about 28-feet below the mean low waterline. This report describes the repairs to the Z-loop in Slip 2 at the Norfolk Deperming Facility, Naval Station, Norfolk, Virginia.
