Design Structural Capacity
Facilities Description. Includes a summary of the history of the facility
structure including the date of original construction, type of structure, length of berth,
deck elevation, depth of water (MLL datum) and a description of the fender system. The
intent of this section is to give the reader a solid background on the particulars of the
structure while being concise. In addition to structure description, the current use of the
facility should also be described. The vessel complement as well as the type of service
(I, II, III, or IV) should be noted. See MIL-HDBK-1026/4, Handbook for Mooring Design.
Design Structural Capacity. This section consists of a table reviewing
mooring hardware data associated with the facility. The data within this table includes:
mooring hardware type and quantity, design load rating of the hardware, the calculated
load capacity of the hardware if manufacturers data is not available, and the design
and/or calculated capacity of the base structure. This table is a structural summary
intended to provide the reader with information required to determine berthing capacity.
Existing Condition. This section provides a summary of the conditions
found during the inspection. A discussion of hardware rated at #3 or #4 is included to
highlight conditions that warrant attention. Following the existing condition text, are
photo pages that present a photographic example of each type of hardware found on
the facility and photos of anomalous conditions. Following the photo page(s) is the
figure showing the 3-D perspective view of the facility (when requested). Following this
is the figure (drawing) showing the plan view of the facility with the condition of the
fittings and fender system noted. Following this is the data table. The data table has all
the information available about each piece of mooring hardware. This information
includes; hardware #, node #, x COORD., y COORD., z COORD, type of hardware, line
pull rating, and the condition of both the hardware and it's support structure.
Key Personnel. Each report should have a list of key personnel
responsible for organizing, conducting, and implementing the investigation.
Load Test Procedures. This section will include a description of any load
testing undertaken. The level of testing, quantity and location of load tests will be
described. (See Appendix B.)
Calculations. All calculations to determine the load capacity of mooring
hardware and/or supporting structures is presented in this appendix.
Mooring Hardware Inspection Records. The actual mooring hardware
inspection records should be included in this section.
Deck Fitting Load Test Reports. The load testing reports should be
presented in this section.
References. All references used in the body of the report should be
identified in this section.
3-D MODEL. A three dimensional model of each facility will be generated
when requested for Level 2 inspections in AutoCAD Release 14 or greater to assist
