CHAPTER 2: FACILITY PLANNING
LOCATION AND ORIENTATION.
The location and alignment of piers and wharves in a harbor should consider
factors such as:
harbor line restrictions,
prevailing wind and current directions,
clearance between moored or passing vessels,
environmental permit restrictions,
port regulations and
For further discussion and criteria, see UFC 4-150-06.
Orientation for Environmental Conditions.
To the extent practicable, orient piers and wharves so that a moored ship is
headed into the direction of the prevailing winds and currents. Thus, the forces
induced on mooring lines by these conditions would be kept to a minimum. If
such an arrangement is not feasible, consider an orientation in which the wind or
current holds the ship off the facility, although do not overlook the difficulty in
mooring a ship under such conditions. In locations where criteria for both wind
and current cannot be met, orient the berth parallel to the direction of the more
severe condition. At locations exposed to waves and swell, locate the facility so
that a moored ship is headed into the wave or swell front. If planning criteria
dictate that a pier or wharf be oriented so that a moored ship is positioned
broadside to the prevailing winds, currents, or waves, consider breast-off buoys
