PART C - WATERFRONT FACILITIES
Multileg mooring systems.
Single-point mooring systems (mono buoy).
Jetties: Jetties are used when the water depth or the shoreline is unsuitable for bringing in tankers.
Docks and piers: Docks or piers (Figure 5-1) are the most secure for unloading tankers. Security is
easier to maintain. Access to the tanker is easier in case of emergency and for maintenance. They are
protected from winds and tide and should be separated from other classes of supply. The depth should
be at least 10 feet of water under the biggest tanker you expect to receive fully loaded at mean low tide.
