7.0 ASHORE INSPECTION AND REFURBISHMENT OF ANCHORS
7.1 GENERAL
7.1.1 SCOPE. Anchors for fleet moorings generally require very little maintenance
and are seldom subject to failure. Although little maintenance is expected, this
chapter will cover the maintenance checks that should be performed whenever an
anchor is removed from service. Maintenance will encompass inspections, tests, and
repairs of the anchors.
7.2 INSPECTION AND REFURBISHMENT
7.2.1 GENERAL. The primary purpose of inspecting an anchor is to determine its
general physical condition and its suitability for reuse. The inspection of an anchor
should only be conducted when the anchor is either temporarily aboard a barge or
in a storage area ashore. There are two types of anchor inspections: preliminary,
which can be conducted either aboard a barge or ashore, and detailed, which is
normally conducted ashore. These inspections should be accomplished as soon as
possible after the anchor is removed from the water.
7.2.2 PRELIMINARY INSPECTION. The purpose of a preliminary inspection is to
determine whether an anchor is in satisfactory condition for continued operational
use. If abnormalities are found and the condition of the anchor is suspect, then a
detailed inspection of the anchor is performed. The preliminary inspection of an
anchor will include the following:
Clean the anchor with a stream of water from a high-pressure hose.
q
Take at least two caliper measurements of the wire diameter of the
q
anchor shackle. One measurement should be taken at the wear zone of
the lugs of the shackle. If the wire diameter of the shackle measures
greater than 90 percent, the shackle is accepted. If the measurement is
90 percent or less, the shackle must be replaced.
