3.1.4 PERSONNEL. Because in-service inspections are conducted offshore, and often
under less than ideal conditions, experienced personnel, as well as reliable
equipment, are required to accomplish these tasks. Topside personnel or divers will
be used to clean and inspect a representative portion of the buoy hull and chain
assemblies. The inspection report of their findings will then be used to assess the
condition of the entire mooring.
Measurements taken, observations made, and
data accumulated must, therefore, be highly accurate and complete in these
instances.
3.2.1 GENERAL. The following paragraphs contain descriptions of the four basic
t y p e s of in-service inspections and provide guidelines for performing these
inspections.
3.2.2 ANNUAL SURFACE INSPECTIONS. Shore activities that operate and maintain
fleet moorings must inspect the visible portion of each mooring buoy at least once
each year. The purpose of this annual surface inspection is to ensure that the buoy
and its topside hardware, fenders, and chafing strips are in satisfactory condition,
and to verify that the mooring has not been dragged from its proper location.
3.2.2.1
Buoy Inspection. The buoy should be closely examined to determine its
overall condition. The following should be documented:
Caliper measurements of the upper jewelry whenever these appear
q
to be excessively worn out or in marginal condition (see Figure 3-l).
in addition, any excess top jewelry or wire rope cables attached to
q
the buoy should be reported.
Physical damage such as holes, dents, metal distortion, or listing
q
(see Figure 3-2).
Measurement of the buoy's freeboard.
