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 ...

Since the 1970s, several fixed concrete platform designs have been developed. Most of the designs have in common a base caisson (normally for storage of oil) and shafts penetrating the water surface to carry the topside. In the shafts normally utility systems for offloading, drilling, draw down and ballast are put up. [citation needed]
States require a drilling permit before a well begins drilling. Requirements to receive drilling permits generally include minimum setbacks from lease or unit boundaries, and adequate casing and cementing programs. States generally require permits for or notices of major work done on a well, and periodic reports of oil and gas produced.
Aug. 9—AUSTIN — The Railroad Commission of Texas issued a total of 772 original drilling permits in July 2023. The total includes 681 to drill new oil or gas wells, 6 to re-enter plugged ...

[1] In 1995, H.B. 2304 was enacted, which required that the Secretary of State make the Administrative Code available ...
A DeLong pier is a type of elonged ersatz pier constructed from prefabricated barge-like sections and simple caissons driven into a harbor's seafloor. First used during the Vietnam War at Cam Ranh Bay , the DeLong pier was originally designed shortly after the Second World War by the DeLong Corporation, and a prototype was constructed not long ...
