Drilling Rigs: Offshore Types

Offshore drilling rigs come in different sizes, configurations, and designs. Each of them is specifically designed to operate under certain conditions which can be from shallow waters to great depths to parts of the world where the weather can be severe or unpredictable. An oil rig, specifically is often towed or constructed on location.

Below are some of the most common types of offshore drilling machines that are available in the industry:


This type of drilling rig is used in shallower bodies of water or less than 80 ft. A submersible rig platform is often transported to the exact location of drilling under tow. It is then sunk until it can rest on the floor of the ocean. They are being kept is place because of their weight, or in certain situations, it may be necessary to depend on a heavy-duty anchor in order to secure the platform in place.



This one is constructed as either a remodeling of an old vessel or a completely new build. Drill ships are self-powered type of drilling rigs. For it to remain in place over the drill target, modern ships rely on control systems and latest automated technologies, whereas the re-fitted vessels are prone to be more dependent on the regular anchor systems. A fully-equipped drillship that has the latest technology for its maintaining position makes such drilling platforms highly-effective for use in waters in which other types of rigs may not be able to penetrate.



This is a kind of oil rig that comes with specialized legs that are designed to be submerged deep below the surface as soon as the platform is placed over the drill target. This rig type can also operate in very deep waters, usually in the region of more than 650 ft. or even more than that. This is also towed fully erected into a specific position. As it reaches the ocean surface, the rig will keep to jack down until the actual rig begins to rest at enough distance above the surface of the ocean (usually in the region of 50 ft.).


Production Platform

A permanent platform is often seen with the production platform made on site that has been confirmed to provide a significant deposit of oil or gas. Once the platform has been constructed on site, it will be a static structure which means that it cannot be relocated to a new location in the future.

Knowing these different types of rigs is very important in order to complete different types of drilling tasks. If you have the right one for your project, you can guarantee the right results. With this, you will not be wasting your time and effort. If you are not sure of what type to use, be sure to do your research first.

Though this one may sound funny, but some kitchen ingredients can do wonders when it comes to cleaning. Vinegar is a kind of acid that is acetic. It can effectively remove dust from the tank. You just have to fill the tank with vinegar and leave it overnight. The next day, you need to drain the mixture and rinse the tank with water. Make sure that no acid is left in the tank. As soon as you have drained everything, rinse the tank with gasoline and other premix. This will help avoid rusting.



Another popular fuel tank cleaning option is acetone. Create a mixture by adding 2 liters of acetone and pour half of it to the tank. Then shake it aggressively so all dust will be removed inside. Check it from time to time and repeat this process with the remaining mixture.

After making use of these elements, it is very important that you rinse the tank properly with water so all remaining dirt will be removed.
