Site plans Site plans can provide layout data and in some cases
will have sufficient detail to show mooring hardware position. This data is
often out dated and should be confirmed.
Hydrographic survey plans Hydrographic data is important to
establish depth of water at the berth.
Calculations. Design calculations to establish the capacity of the
supporting structure. Calculations used to determine loads on hardware.
Existing Reports. Previous inspection reports such as an Underwater
Facilities Inspection Report, Prior Mooring Hardware Condition report or Annual
FIELD INSPECTION / DATA GATHERING.
General. The purpose of any mooring hardware inspection is to gather
information to assess the condition of the mooring hardware system inspected. The
level of inspection will determine the amount and type of information gathered. The
inspection will focus on gathering the following information:
Identification of damage
Confirmation of available data
Changes in the known supporting structure
Identification of potential problems with interacting equipment and
Establishing the position of mooring hardware and fenders
General condition of fender system and hardware
Gather available background information at the site.
Field Inspection. Personnel assigned to conduct a field inspection of
mooring hardware should acquire the appropriate tools necessary to accomplish the
work. The level of inspection will dictate the required tools. All levels require appropriate
record keeping. Information should be recorded in logbooks. The time and level of effort
required to conduct an inspection will depend on the amount of background information
that is available, level of inspection required, site conditions, site access and activity, as
well as the skill of the inspector.
Hand Tools. Various hand tools are required to accomplish the task of
inspecting mooring hardware. Tape rules, folding rules, measuring wheels, and in some
instances surveying equipment will be required to perform tasks such as: dimensioning
structural components, finding the position of mooring hardware, and measuring
distress within the structural system. Other tools such as wire brushes, chipping
hammers, and scrapers can be used to clean and uncover structural components that
are not readily visible. Marking devises such as paint stick, keel, paint and ink pens can
be used to establish identifying marks on each hardware unit for reference.
