Responsibility for US Navy ships that are designated ``Inactive`` resides with the Inactive Fleet Division of the Naval Sea Systems Command. Many of the ships that are removed from active service are retained in case of future need. Inactivation and preservation procedures must be thorough and long lasting, for the inactive status period may be as much as 20 years or more. One of the principle techniques used is that of cathodic protection, in which electric potentials are used to retard corrosion. In 1987 the Oak Ridge National Laboratory (ORNL) was engaged by the US Navy Inactive Fleet to review the manner in which cathodic protection (CP), was being implemented at the various Naval Inactive Fleet Maintenance Facilities (NISMFs).
