Jack-up rigs are mobile offshore drilling units used primarily for oil and gas exploration. They consist of a floating hull with legs that can be lowered to the seabed, allowing the rig to elevate above the water surface. This design provides stability and safety while drilling in shallow waters. These rigs are typically towed to a drilling site and then positioned over the desired location. Once in place, the legs are lowered, and the platform is raised, creating a stable working environment. Jack-up rigs are commonly used in water depths ranging from 10 to 400 feet.
