CHAPTER 5
ANCHOR SYSTEM DESIGN PROCEDURES
GENERAL ANCHOR DESIGN PROCEDURE. Anchor systems ultimately
5-1
hold the mooring loads in fleet mooring systems. Anchors are used on both ships and
in mooring facilities, so selection and design of anchors are included in this section.
The type and size of anchor specified depends upon certain parameters,
such as those shown in Table 5-1.
The most commonly used anchors in DOD moorings are drag-embedment
anchors and driven-plate anchors, so they will be discussed here. Other types of
specialized anchors (shallow foundations, pile anchors, propellant-embedment anchors,
rock bolts, etc.) are discussed in the NCEL Handbook for Marine Geotechnical
Engineering.
Figures 5-1 and 5-2 illustrate typical drag-embedment anchors. Figure 5-3 illustrates a
driven-plate anchor. Some characteristics of these two categories of anchors are given
in Table 5-2.
