Jackup rigs are so named because they are self-elevating with three, four, six and even eight movable legs that can be extended (“jacked”) above or below the hull. Jackups are towed or moved under self propulsion to the site with the hull lowered to the water level, and the legs extended above the hull. The hull is. .
A jackup rig or a self-elevating unit is a type of mobile platform that consists of a buoyant fitted with a number of movable legs, capable of raising its hull over the surface of the sea. The buoyant hull enables. .
An early design was the DeLong platform, designed by Leon B. DeLong. In 1949 he started his own company, DeLong Engineering & Construction Company. In 1950 he constructed. .
A jackup rig is a barge fitted with long support legs that can be raised or lowered. The jackup is maneuvered (self-propelled or by towing) into. .
Mobile offshore Drilling Units (MODU)This type of rig is commonly used in connection with . There are more jackup rigs in the worldwide offshore rig fleet than other type of mobile offshore . Other types of offshore rigs include

To decide on a site with a potential oil/gas payout, Geologists and Geo-Scientists work their ways in and around the information collected off the areas with possible oil or gas reservoirs. Survey vessels with or without Dynamic Positioning systemsare hired for seismic surveys. These maritime vessels are equipped. .
Once the site is identified and selected, boundaries are surveyed and earmarked by the local governing body for Energy and Resources. Studies for impact on the environment are carried out. After determining the potential energy sites, oil companies are then. .
After the potential energy-rich blocks are legally cleared, oil companies pursue their investments by employing mobile drilling units that are temporarily acquired and are able to move on to. .
These self-contained drilling structures are as good as the drilling barges only to the exception that these massive structures are positioned onto. .
They are mostly utilized for shallow water drilling in calm water conditions. Drilling equipment is placed on to the barges’ decks and towed to.
