8.3.2.2
chain joining links (see Figure 8-7). The installation must be completed
onshore or on the crane barge before the mooring is installed. A reliable
electrical path is normally provided by a wire rope continuity cable
clamped to the Iink portion of the anode and attached to the chain as
described in Paragraph 8.2.3.4.
C l u m p Anode. Clump anodes are usually installed ashore during
8.3.2.3

chain, a wire rope continuity cable must be clipped or clamped to the
anode's hairpin and attached to the chain as described in the following
paragraph.
Wire Rope. The wire rope, used to provide the electrical continuity, is
8.3.2.4
