An offshore rig is a tool that functions to mine oil and gas. An offshore rig is a rig that operates in the middle of the sea. Another name for offshore rigs is marine rigs. As the name implies, this type of rig operates in waters such as the sea, lake, river, or swamp.
Because it is located in the water, it is necessary to use a ship or helicopter to get to this type of rig. Helicopters are more suitable because the type of ship used is a fast boat that gives shocks that can make seasickness. Working on a marine rig will find routine work. It’s just that, the workers will get complete and well-maintained facilities. Usually, on marine rigs, there are massage chairs to a gym room.
Types of Offshore Rig Based on the Depth of the Waters
Rig can be divided into 5 types, including:
Inland Barge Rig
Inland Barge Rig is a barge with a rig on its deck. This type of rig is used for drilling in shallow waters such as swamps or river deltas. Inland Barge Rig is divided into two more types, namely Swamp Barge and Tender Barge. Swamp Barge functions to drill waters with a maximum depth of 7 meters. Meanwhile, the Tender Barge serves to drill deeper waters.
Jack Up Rig
Jack Up Rig is a rig that has a platform that can float and has three or four legs that can go up and down. The operation of this type of rig depends on the movement of the legs. To carry out drilling, the rig legs must touch the seafloor so that the rig body on the surface of the water forms a fixed platform. To be able to move the legs of the rig must go up so that the rig is floating and can be towed by the ship. Jack Up Rig can function to drill waters with a depth of between 5 and 200 meters.
Semi-Submersible Rig
Semi-Submersible Rig is a floating rig. To keep it from moving on the water surface requires a mooring rope to tie and an anchor to hold it in place. This rig is usually a replacement choice if the water is too deep for the Jack Up Rig. This rig is famous for its stability. Therefore, this type of rig is suitable for sea areas with large waves and bad weather.
- Submersible Rig
The submersible rig has two floating tubular sections. The main part will submerged in the seabed. And the second part will support the rig.
Drill Ship
As the name implies, this rig is a ship. Drilling equipment installed onboard. A system thruster computer-controlled will control the ship. Because they can move and have a large capacity, drillships often used at sea, which is far from land. This type of rig usually used to drill in deep-sea areas.
Those are several types of offshore rigs that are often used to drill in the sea or water areas. These various types of rigs make for interesting souvenirs. You can check and order it at Minikraf.
