Berths providing Mooring Service Type III are especially high
priority, because the ships under repair at these piers and wharves
cannot get under way in case of an approaching storm.
High capacity fittings secure a larger portion of a mooring load at a
given facility, and should be assigned higher priority (i.e. a Special
Mooring Bollard 'A' holds more load than a 30-inch cleat, so the
bollard is assigned a higher priority).
Older facilities not previously pull tested are more likely to suffer
from structural deterioration and should be assigned higher priority.
Testing recommendations are shown in Table B-1.

Personnel. If contracted, the testing of mooring hardware should be
conducted under the direct supervision of a Registered Professional Engineer (P.E.)
who has experience in the design and inspection of marine structures. At a minimum
the supervising engineer (P.E.) should be on site and involved in the testing to assess
