to see that the fender shell is not cracked or separated around end
Condition of the fender elastomer shell. Check for cuts, tears, and
punctures. Record the size and location of damage on a sketch.
Measure or estimate the diameter of the fender at its smallest point
to record permanent set.
Inspections will be done by walking the pier and using a small boat.
Record keeping for foam-filled fenders is very important. In this
regard, the fenders should be treated as an item of high-cost equipment rather
than an appurtenance to a fixed facility. Each fender should have a unique
identification number with a history record that includes date of procurement,
manufacturer, date of installation or when fender was put into service, and berth
location if permanently installed.
INSPECTION OF QUAYWALLS. Quaywalls are an integral part of
wharves and should be included when other pier components are inspected.
Deterioration of quaywalls is indicated by:
Shifts in horizontal and vertical alignment of sheet piling.
Wash-out of substrate under the sheet piling, particularly at the toe
of the structure.
Alignment shifts can be detected by visual observation. A complete
description of shifts and any apparent cause should be provided. Deterioration of
wood is covered by Paragraphs 5-4 through 5-6. Wash-out may be detected by
visual inspection in clear water at low tide. If not, then an underwater inspection
is required. Figure 5-20 "Quaywall Surface and Underwater Inspection
Checklist," is a useful guide.
