Pile-supported fender system on the James P. Houlihan Memorial Bridge. Fender systems attached to the pier with the goal to absorb the vessel impact. Their ability to withstand a typical ship collision is low. Fenders are built using a variety of materials: [8] thin-walled concrete box; thin-walled steel membrane steel; rubber.
Wood pilings grouped into a pair of dolphins serving as a protected entryway to a boat basin. A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids.
Anchor piles are typically designed to resist both horizontal and vertical loads. The axial holding capacity of the anchor pile is due to the friction along the pile-soil interface, while the lateral capacity of the pile is generated by lateral soil resistance, where the anchor's orientation is critical to optimising this resistance.
A pile of D fenders. D-type fenders are commonly used on vessels as well as small jetties. D fenders are commonly extruded in solid rubber (hollow and solid sections) in water and weather resistant EPDM compound. Similar to that of D fenders, Double D fenders (or known as B fenders) are also extruded and provided with steel inserts if required. [1]
A heavily damaged piling structure can be reinforced by cutting out the damaged section and replacing it with preservative-treated wood. [14] Wrapping piles with plastic barriers can provide protection from marine borers for 25 years or more. [14] Pile reinforcement with concrete can be sufficient by filling the void with coarse stone and ...
The suction caissons are in many cases easier to install than piles, which must be driven (hammered) into the ground with a pile driver. [4] Mooring lines are usually attached to the side of the suction caisson at the optimal load attachment point, which must be calculated for each caisson. Once installed, the caisson acts much like a short ...
