INSPECTION OF SYNTHETIC MATERIALS AND COMPONENTS.
Inspection of synthetic materials and components is subdivided into the following
Structural Members. Structural members should be inspected
annually. The inspection should detect:
Cracked, worn, brittle, or deformed plastic railings, stanchions,
gratings, light standards, or piping; loose or damaged fittings and
Cracked, worn, or deformed rubber resilient fender components,
and/or loose or damaged fittings and connections.
Basic inspection procedures are the same as those outlined for timber
or concrete structures.
Coatings, Patches and Jackets. Coatings, patches, and jackets
should be inspected annually, or more frequently, depending on the failure rate of
the application. The inspection should detect:
Pits, cracks, scars, or abrasions in coatings.
Cracked, loose, or dislodged epoxy patches.
Punctures, brittleness, tears, rips, or abrasions in fabric, or
unlocking of fabric seams in pile jackets.
Basic inspection procedures are the same as those outlined for timber, concrete,
and steel structures.
Foam-Filled Fenders. Foam-filled fenders should be inspected more
than normal pier inspections and should cover:
Condition of the fender-to-pier connection hardware. Check for
operability and signs of corrosion. Check to ensure that the fender
is constrained horizontally so that it contacts the bearing surface for
its full length. Ensure that the fender is free to vertically float with
the tide and rotate around its long axis.
Condition of the fender chain and tire net for net fenders. Check to
see that the chain is symmetrical on the fender and that the end
fittings are in good working order. Ensure that the chains are
protected from the ship hull by the tires, and that the net is not
Condition of end fittings on netless fenders. Check to see that the
fittings are in good working order, and corrosion is minimal. Check
