pile tips, it was noted that there was lower
unit skin friction along the shaft of the pile
during the initial PDA testing. However,
given the setup characteristic of the silty
marine overburden, the SPIN FIN® piles
demonstrated a greater amount of setup
than pipe piles without fins over time.
This method of using PDA testing to
verify the capacity of SPIN FIN® piles is a
new and innovative method for confirming
analytical tension capacity of this pile tip.
Unique design applications
The concrete floating pontoons serve as the
passenger load/unload area for the cruise
ship berths. The pontoons also provide the
breasting face for the cruise ships themselves.
The mooring structures for the pontoons
were made up of all vertical pile mooring
dolphins. These mooring dolphins allow
the pontoons to rise and fall with the large
25-foot tides in Juneau.
The all-vertical pile mooring frames
presented a challenge at the site because
the dolphins were positioned at different
mudline and bedrock elevations along the
breasting line. Since all the vertical piles
have differing stiffness characteristics based
on the length of the pile, it was important
to consider the stiffness response of these
dolphins when a breasting load was applied
to each from a cruise ship.
PND modeled the individual dolphin
stiffness in series with the stiffness associated
with the ship fenders. This modeling
was done to ensure that the berth provided
a uniform structural response along the
length of the berth so that the wind loading
on the ship would be uniformly distributed
along the ship. By modeling stiffness
response of the cruise ship berths, PND
adjusted the geometry of the pontoon mooring
dolphins in order to create a uniform
stiffness response along the berth. In areas
with a shallower mudline or surface bedrock,
the pontoon mooring dolphins used
six, all vertical 48-inch-diameter piles. In
zones where there was deeper mudline and
