The type 4 pierhead section, which supports the
container handling crane, contains seven internal and
three external spudwells. Six reinforced PI pontoons
are also included.
CONSTRUCTION OF FENDER
A fender section is a 1x15 structure incorporating
three fender spudwells (fig. 10-40). Fender piles are
driven through the fender spudwells after the
causeway is elevated (fig. 10-41). The fender section
can then rise and fall on the piling. A series of
foam-filled fenders are strung on the outboard side of
the fender system to absorb impact from lighterage.
Since it is only one pontoon wide, the fender system
uses P5 pontoons as end-to-end connections instead of
Figure 10-41.ELCAS fender system.
