 3.0 INSPECTIONS
3.1 GENERAL
3.1.1 OVERALL REQUIREMENTS. All mooring components, either in use or in
s t o r a g e , must be periodically inspected to determine their current material
condition and their future maintenance requirements. The importance of these
i n s p e c t i o n s cannot be overemphasized because the effectiveness of any
maintenance program will always depend on how often and how well these checks
a n d services are performed. Inspection plans, therefore, should take into
c o n s i d e r a t i o n the critical elements of frequency of inspections and the
thoroughness, completeness, and quality of work.
3.1.2 INSPECTION CLASSIFICATIONS AND TYPES. For the purposes of this manual,
inspections are classified as either in-service or out-of-service. In-service inspections
are performed on installed moorings; out-of-service inspections are performed on
components stored ashore. There are four basic types of in-service inspections, as
follows:
Annual surface inspections.
q
Underwater inspections.
q
Lift inspections.
q
Damage/failure
inspections.
q
The above in-service types are addressed and discussed in this chapter. Out-of-
service inspections are covered in chapters 5.0,6.0,7.0, and 8.0.
3.1.3 PURPOSE. The primary purpose of in-service inspections is to determine the
general physical condition of the buoy(s) and chain assemblies. The results of these
inspections are used to decide if a mooring is safe for continued use. Routine
inspections also provide an opportunity to detect and remedy minor material
Future maintenance requirements are strongly dependent on the
deficiencies.
