Multiple tension lines are used to secure a vessel

next to a pier/wharf. Compliant fenders, fender
piles and/or camels keep the vessel offset from
the structure. A T-pier may be used to keep the
ship parallel to the current, where the current
speed is high.
Spud Mooring
2-3
Multiple vertical structural steel beams are used to
secure the vessel, such as a floating drydock.
This type of mooring is especially effective for
construction barges temporarily working in shallow
water. Spud moorings can be especially
susceptible to dynamic processes, such as harbor
seiches and earthquakes.
