protection, and similar activities. Remove snow around fire hydrants to make
them accessible to firefighting personnel and apparatus. It may be necessary
to remove snow and ice to provide connections to the established drainage
systems and to maintain drainage openings to their full capacity.
When practicable, a wobble-wheeled roller should make low speed
passes over all well used bituminous surfaces at least once during the summer
months when the outside temperature is above 75 degrees F.
Bridges. Bridges should be periodically inspected for verification
3.3.14
of structural integrity in accordance with NAVFAC MO-126, Inspection of
Bridges and Trestles. Corrosion or physical damage that threatens the
continued survivability of bridges should be repaired as necessary.
Boiler Plants. Boiler settings should be inspected periodically to
3.3.15
guard against sweating and corrosion of the external surfaces of the pressure
parts. Use of coke jacks or similar heating stoves at convenient points may
be necessary during extended spells of damp weather accompanied by a rising
temperature. The discontinued portions of gas-burner systems should be
checked periodically with a pressure gauge to ensure that leaking valves are
not allowing gas to enter areas withdrawn from service.
Drydocks
3.3.16
Inspection. Para. 3.1.2 details the types of inspections, and
3.3.16.1
Appendix A lists suggested inspection frequencies for drydock-associated
equipment and systems. The actual frequency of these inspections should be
determined by the activity and included in the caretaker maintenance planning.
Additional factors in determining the inspection frequencies are the
anticipated time of inactivation, the expected future mission, and the
economics of maintaining the structures and equipment.
Included in this planning effort should be a detailed inspection to
be made 30 to 60 days after inactivation is completed. The condition of the
pumps, motors, valves, mechanical equipment, electrical equipment, underwater
hull of the entrance caisson, sluice, and stop log gates should be determined.
Effects of corrosion, verdigris, tarnish or mildew should be estimated.
Inspections should disclose where exterior surfaces and equipment require
preservation.
3.3.16.2
leakage in the dock and caisson should be checked monthly and after heavy
rains for evidence of failure. For drydocks with the caisson left in place,
test run the pumping capability every 90 days and perform minor operator
maintenance.
Pumps should be overhauled and repaired as required, including
suction and discharge system and electrical controls. Periodic inspection of
stop logs is necessary to ensure watertightness of the pumpwell.
