These floating units must maintain stability in the face of waves, wind, and currents, utilizing sophisticated ballast systems and mooring lines to remain in position without drifting. Attached to this spar is a large, buoyant deck at the surface where the drilling equipment and crew quarters are located.
Deep Water Platforms Versus Fixed Structures: Floating Stability and Design Differences
Fixed Not all oil rigs float in the same way, and the category determines the design solution. Semi-Submersible Platforms: The Stable Giants One of the most common types of floating rig is the semi-submersible platform.
This elevation provides a stable, level platform for drilling, free from the sway of surface waves, although they are incapable of operating in deep water due to the length limitations of their legs. Tension-Leg Platforms: Pulled Down.
Deep Water Platforms Versus Fixed Structures: Floating Stability and Design
These rigs sit on a barge-like hull while traveling to the drill site. The vast majority of offshore platforms are built on a superstructure made of steel, which is denser than water, so they rely on a large hollow base filled with air to achieve the necessary displacement.
