MIL-HDBK-1130
a)
Electrical. Paint cable insulation and seal cables, as
specified by the manufacturer's instructions. Turn off all
circuit breakers. Remove all temporary disconnect switches,
controllers, and panel boards. Repair circuit breaker
enclosures. Reinstall gaskets and covers. Repaint any worn
areas on all corrodible metal surfaces. Touch up any
galvanized surfaces have been worn or damaged. Wood service
hood enclosures and timbers should be treated with
preservative. Treat insulator mounts, nongalvanized and
nonpainted steel, and metal nameplates with rust-preventive
compound.
b)
Mechanical. All existing rust should be removed from exposed
pipes and valves by sandblasting. The exposed pipes should
then be steam-cleaned and repainted in accordance with Military
Standard (MIL-STD)-101B, Color Code for Pipelines and for
Compressed Gas Cylinders, if at a service hood, or treated with
a preservative compound. Install plastic caps on threaded ends
of fresh water and salt water outlets. Ensure existing
cathodic protection systems are operating properly; repair them
if necessary.
Graving Docks. Inactivation procedures for graving drydocks vary
2.3.3.2
according to the anticipated time of inactivity, mobilization requirements,
economic considerations, climatic conditions, etc. However, before these
specific procedures can be identified, the method of drydock storage should be
determined, i.e., dewatered or flooded, caisson in place or removed. Each
alternative presents different caretaker maintenance and reactivation problems
that should be considered prior to inactivation. For example, if the drydock
is stored in a flooded state with the caisson removed, dirt and silt can
accumulate in the dock basin; whereas with the caisson in place, the trapped
water can stagnate and should be chemically treated. Once the method of
inactivation is decided, the specific inactivation procedures can be
identified.
a)
Dock Basin. If the drydock is to remain dewatered during
inactivation, it should be thoroughly inspected for leaks
through the floor, through the walls, and around the seals of
and tunnels should also be inspected. All leaks discovered
should be repaired. Leaks in docks that are to remain flooded
should be identified but need not be repaired unless they pose
a threat to the structural integrity of the drydock. All other
concrete surfaces should be inspected while the dock is
dewatered for spans, cracks, and other defects that could
worsen during the inactive period. Any major, or potentially
major, structural defects identified should be repaired.
