Semi submersible drilling rig design

Mobile offshore drilling units (MODU) Semi-submersible rigs make stable platforms for drilling for offshore oil and gas. They can be towed into position by a tugboat and anchored, or moved by and kept in position by their own azimuth thrusters with dynamic positioning. The International Maritime Organization. .

Offshore drilling rig design

Offshore platforms have many uses including oil exploration and production, navigation, ship loading and unloading, and to support. . There are two types of offshore drilling rings/platforms. The first type is moveable offshore drilling rigs that can be moved from one place to another and the second type is the fixed rigs/platforms. . Different types of offshore oil rigs and platforms are used depending on the offshore oil/gas field water-depth and situation. Rigs are used for the drilling of the wells and platforms are installed in the field for extracting oil/gas operation. Main types of rigs and. . Drilling barges are used mostly for inland, shallow water drilling. This typically takes place in lakes, swamps, rivers, and canals. Drilling barges are. [pdf]

Rig based drilling

A drilling rig is an integrated system that , such as oil or water wells, or holes for and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill , , or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called .
