Monopile Dolphin A single pile dolphin usually consisting of a large diameter
concrete or steel pipe pile filled with concrete. Monopile dolphins can be used as
mooring or breasting dolphins. When used as a breasting dolphin, the monopile dolphin
is faced with fendering elements.
Mooring Dolphin - A freestanding pile supported or solid filled structure used for
mooring vessels. Mooring dolphins are usually placed at the bow or stern of a moored
ship to provide mooring points to attach breasting lines, bow lines and stern lines.
Pier - A pier is a structure that projects out from the shore into the water. A pier is
oriented either perpendicular to or at an angle with the shore. It may be used on both
sides, although there are instances where only one side is used because of site
conditions or because there is no need for additional berthing.
Port of Call - Any port where a ship stops along the way other than its homeport, or a
stop at a fueling pier, an ammunition pier, a supply pier, or a repair pier. The only real
requirements for a port of call would be that it has sufficient dredge depth and that it
provides secure mooring. Ship does not go cold iron in port of call and uses its organic
systems. However, local determinations and justifications can warrant adding specific
features at ports of call. Many of the new classes of ships have concepts of operations
and special mission requirements that have resulted in making accommodations at
ports in forward operating areas that ordinarily would not be required, i.e. hotel services.
These are handled on a case by case basis and driven by operational requirements.
Slip The space between two approximately parallel piers or the space formed by a cut
into the land that provides two approximately parallel mooring faces.
Wharf - A wharf is a structure oriented approximately parallel to the shore. Ships can
only be moored at the offshore face of a marginal wharf. When water depths close to
shore are not adequate to accommodate deep draft ships, the wharf, consisting of a
platform on piles, is located offshore in deep water and is connected to shore along its
length or at one or more points by pile-supported trestles, usually at right angles to the
