a DA Form 5456-R. Patrols also prevent or hinder sabotage or theft.
They are sent out often and at different times each day so that no one
can predict when a patrol may be in a specific area. Usually, patrols
are not sent out during the night because leaks are hard to spot when
flashlights must be used. Patrols can be made on foot, by using a jeep
or truck, or by using a small airplane or helicopter.
Foot and Motor Patrols.
Foot and motor patrols are equipped with
radios or telephones, coupling wrenches, grease, gaskets, and repair
clamps to make minor on the spot repairs. Motor patrols can carry more
equipment and cover more territory than foot patrols, but they are
limited to areas where the pipelines runs alongside a road. Foot and
motor patrols report major leaks to the pump operator as soon as
possible.
Air Patrols.
Air patrols are used only when there is a need to check
out the pipeline quickly. They are also used in areas where foot and
motor patrols are difficult or impossible to use because of the rough
terrain. This is especially true in mountainous areas. Air patrols
require fewer persons to patrol more pipeline than do foot and motor
patrols. However, air patrols may be limited because of bad weather.
Air patrols report all problems by radio so that repair crews can be sent
to work on the pipeline.
