Also called caissons, drilled shafts, drilled piers, cast-in-drilled-hole piles (CIDH piles) or cast-in-situ piles, a borehole is drilled into the ground, then concrete (and often some sort of reinforcing) is placed into the borehole to form the pile. Rotary boring techniques allow larger diameter piles than any other piling method and permit ...
Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is ...
Suction caisson solution. Suction caissons (also known as suction buckets, suction piles, or suction anchors) are a new class of embedded anchors that have a number of economic advantages over other methods. They are essentially upturned buckets that are embedded into the soil and use suction, by pumping out the water to create a vacuum, to ...
Tsunamis are a class of wave which occur relatively seldom but can have a devastating effect due to the large amounts of energy they can carry over long distances at high speeds. The depth to which a wave has significant motion is a function of wave length, and to a lesser extent, on wave height. [1]: Ch 1.7 Wind; Tides and storm surges
The caisson provides buoyancy during construction and towing and acts also as a foundation structure in the operation phase. Furthermore, the caisson could be used as storage volume for oil or other liquids. [1] Floating units may be held in position by anchored wires or chains in a spread mooring pattern.

Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations, and other factors.
The Avila Beach and San Simeon piers were already closed due to existing damage and sustained a new round of nature’s wrath. Large waves hammer the Avila Beach Pier on Thursday, Dec. 29, 2023.
