Although discussed previously under fenders, in section 5.0, this type of fender
has been used as a camel for attack submarines at a number of locations.
NFESC has developed a composite camel for use in berthing of submarines; see
Figure 6-1. The camels are manufactured from composite materials intended to
provide an extended service life over steel construction. The camels were
developed and funded under a NAVFAC RDT&E effort and have been
successfully used at SUBASE New London since mid 2000. Although a standard
design for this type of camel is not currently available, additional information may
be obtained by contacting NFESC Shore Facilities Department.
The camel loads are computed from berthing and mooring analysis of the ship,
camel, fender, and structure system resisting the lateral loads. All the ship's
berthing reaction loads as well as current and wind loads are transmitted through
the camels to the pier or wharf structure. Assume all horizontal loads to be
acting uniformly along the length. Design deck elements of large camels for 50-
psf (2394.0 Pa) vertical live load. Check the camel assembly for fabricated
camels for lifting stresses. Where the pick-up points and rigging configurations
are critical to control lifting stresses in the camels, provide clearly marked pick-up
points or pad-eyes. For complex lifting requirements, provide lifting diagrams on
the design drawings.
