GENERAL UTILITY REQUIREMENTS
SHIPS DEMANDS. Ships utility demands and other pertinent data for
individual ships utilities are available from Appendix C. The designer must access this
information in order to obtain the latest design data regarding dockside utilities for all
ship services. In general, ship utility demands for active berthing are based on the
ship's complement without deployed forces such as air wings or marine troops.
Diversity factors are provided for use in determining demand in multiple berthing. If the
designer is basing the project design on a specific ship that is not included in Appendix
C, use data from a similar ship, or obtain the expected demand from NAVFAC CIENG
or USACE. For graving drydocks, refer to UFC 4-213-10. This information is for use at
new facilities and for use in additions, modifications, and replacements at existing
facilities. While means of diversification are provided for multiple ships and multiple
piers by these diversity factors, metered data from existing facilities and ships should be
used for planning and design whenever such data are available.
UTILITY-CONNECTION LAYOUT. Figure 2-1 shows the dimensional
relationships normally encountered in placement of shore utility connections.
APPENDIX C provides size/shape data for typical ship hulls and dimensioned reference
points that define the ship's utility connection locations. Ideally, the locations of shore
utility connections for a given berth would simply correspond to their respective
connection locations on the ship to be berthed. In practice, however, utility-connection
locations can never be ideal, due to largely nondedicated berthing, interference with
other pier or wharf activities, other deck equipment, and the grouping of connections.
The designer must optimize the location of all utility outlet assemblies based upon the
projected berthing mix.
Connection Grouping. Utility connections should be confined to specific
locations along a shore facility so that interference with line handling and other facility
operations is reduced. Connections may be in large groups to encompass all utilities, or
may be in subgroups, such as the following:
Freshwater, saltwater (if required), steam, and compressed air;
Sewer and oily waste; and
POL, when required.
