Offshore oil drilling rigs allow drilling to the ocean floor’s deepest depths. Depending on the kind of project being handled, it can be utilized for land-based drilling, too. Either of these two drilling systems can manage to extract vast quantities of high-value oil from below the surface of the earth for processing and sale in the petroleum market.
Since 2010, with the Gulf of Mexico oil disaster, offshore drilling rigs have become a focal point of public interest.

Before we continue, we must define what oil rigs are and what they are not.

Sonic drill rig manufacturers often say that oil rigs are complex pieces of technical marvels; they are comprised of several components and subcomponents. The following are some of the several types of rigs accessible in the nation.
You will usually find this form of drill rig on tanker hulls. Its drilling equipment or accessories are also attached and are generally taken deep into the sea when carrying out experimental drilling work. Dynamic positioning systems take on the job of keeping the ship afloat.
Another type of offshore drilling semi-submersible equipment utilizes oversized hollow columns or pontoons to float offshore. This type of drilling rig may submerge the rig to the required depth after filling them with enough water. They are most often used when drilling for new wells. Besides, they are sturdy enough to resist the most violent, roughest of seas.
Mobile offshore rigs are among the most common and sought-out drilling rigs in the country, according to Rigzone. They’re named “jackups” and usually come with bottom supports.
The main deck or hull needs structural support from open-truss legs or columns and can dive to a depth of around 350 feet, below sea level.
There are two types of drilling tools utilized in jack-up rigs. The most common and latest is the cantilevered jack-up. Its arm generally extends out from the main deck and features a drilling derrick mounted on it. This enables it to drill with or without the use of platforms.
Fixed platforms can be used to house drilling rigs and other equipment used in opening new wells. Due to their size, they may also accommodate a variety of additional equipment/drilling accessories and even a few staff.
It is typical for this kind of drilling facility to be connected to the surface of the ocean floor. Normally, they are visible on continental shelves reaching depths of around 1,700 feet. They’re also capable of directional drilling, and interconnect them to multiple wells within a 5-mile radius.
