After steaming to the location, the rig uses its engines to jack its hull high above the water surface, resting the structure on the seabed for a stable drilling platform. Semi-Submersible and Drillship Platforms For the most challenging deepwater environments, exceeding 1,500 meters, floating platforms are the only viable solution.
Offshore Production Facilities and Processing Systems Overview
Drillships, converted tankers with a distinctive bow thruster system, offer even greater mobility and precision in positioning, able to operate in the deepest waters while maintaining the ability to transit quickly between locations. Drilling Package: The crown block, drawworks, and rotary table that work together to drill the wellbore, circulate drilling mud, and manage the drill string.
These vessels appear as mobile platforms with three or four massive legs. These immense installations operate in some of the planet’s most challenging environments, from the calm shallows of the continental shelf to the brutal, wind-swept expanses of the deep ocean.

This mobility allows them to be repositioned as projects conclude and new opportunities arise. Jack-up Rigs When water depths exceed the limit of fixed platforms but remain moderate, typically up to 120 meters, the jack-up rig becomes the preferred choice.
