appurtenances in the zone of elevators for CVN (#1, #2, and #3), LHA, or
LHD. At times these ships may have to move off of their normal berth
bridge mark, i.e. move CVN offshore for ordnance load or move LHA/LHD
toward bulkhead for stern gate ramp placement. Objective is to keep
edge of pier free of obstructions.
j. Provide parking for ship's government and privately owned vehicles in
proximity to entrance to the pier or wharf.
k. Provide sufficient security for ships on the pier. Consider minimally
manned ships. See also paragraph 2-6.
Provide safety equipment.
Pier and Wharf Length.
The length of pier or wharf should equal the overall length of the largest ship to
be accommodated, plus an allowance of 50 ft (15.2 m) at each end of the ship.
For aircraft carriers, increase the allowance at each end of the vessel to 100 ft
(30.5 m.) Refer to Figure 2-3. Single berths are used by LHA, LHD (amphibious
assault ships); T-AKE, T-AO, T-AOE, (auxiliary); and CVNs.
The length of a pier or wharf should equal the total overall length of the largest
ships simultaneously accommodated, plus clear distance allowances of 100 ft
(30.5 m) between ships and 50 ft (15.2 m) beyond outermost moored ships.
Refer to Figure 2-3. Multiple berths are used by DD 963, CG 47, DDG 51, FFG 7
(surface combatants) and SSN, SSBN submarines.
Container and RO/RO Berths.
The length of berths used for container or RO/RO berths should account for the
requirements of the container cranes or special ramps. Where shipboard ramps
are used, provide adequate berth length to allow for efficient vehicle
For most classes of submarines, a 50-ft (15.2-m) end distance to a quaywall or
bulkhead is adequate. The nose-to-tail spacing for multiple berthing should also
be a minimum of 50 ft (15.2 m.) However, large submarines such as the Ohio
class (Trident) require 150 ft (45.7 m) or more nose-to-tail spacing and clearance
to bulkhead or quay wall. Where explosive safety distance considerations
