NAVFAC Headquarters, Engineering Field Divisions (EFDs) and
Engineering Field Activities (EFAs)
Provide technical advice and assistance to lead activities and
shore activities having assigned water areas.
Plan, design, and construct channels in compliance with the
guidance stated herein.
NAVFAC Criteria Office will provide technical advice and assistance to
lead activities, shore activities having assigned water areas, EFDs and
Dangerous Cargo Requirements. Anchorages for tankers and similar
vessels should be at least 152.4 m (500 ft) from adjacent berths, and located so that
prevailing winds and currents carry spillage away from general anchorage and berthing
Anchorages for vessels carrying explosives should be separated in accordance
Standards, DOD 5154.45 (DOD, 1978), which was superseded by DOD 6055.9 (DOD,
Shipyard Special Requirements. The following information is provided:
Mission and Requirements. Harbors or sections of harbors designed as
shipyards require special facilities and designs. Shipyard facilities consist of navigation
basins, piers, drydocks, and backland. Outfitting or repair piers are generally arranged
as in Figure 5-15c or Figure 5-15f. Less commonly, where space permits, repair
stations could be arranged along a marginal quay, as in Figure 5-15i. Drydocks may be
either the floating or graving type.
Waterways. The shipyard portion of the harbor requires a channel
sufficiently large to accommodate the largest vessel to be served by the shipyard. The
water area fronting the shipyard should be a navigable basin in which the largest vessel
is capable of maneuvering to and between repair facilities. It is essential that the
shipyard has quiet water and be free of strong currents. Ships at repair are frequently
in "hotel" status and short of the operating personnel needed to operate them in case
currents should tear them loose from their moorings.
Piers. Special considerations for repair and outfitting piers include crane
rails for portal cranes, railroad tracks between crane rails, and special service piping to
shipside galleries or service boxes. For pier design, refer to MIL-HDBK-1025/1.
Drydocks. Drydocks are of two basic types: floating and graving.
Floating drydocks may be moved from place to place and are suitable for servicing
