They consist of a massive vertical cylinder, the "spar," that extends deep below the water line. These are less about floating and more about standing tall.
Buoyancy Principles That Keep Offshore Drilling Platforms Afloat
For a floating structure, the key is to design a hull that displaces a volume of water weighing more than the entire weight of the rig itself. Spar Platforms: The Weighty Solution Spar platforms utilize a unique design that relies on sheer mass for stability rather than wide pontoons.
Harnessing Archimedes' Principle The core concept behind why oil rigs float is Archimedes' Principle, which states that any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. Once positioned, they extend three or more massive legs down to the seabed.
How Buoyancy Keeps Offshore Drilling Platforms Afloat
Fixed Not all oil rigs float in the same way, and the category determines the design solution. The majority of the buoyancy comes from columns that are partially submerged, sitting below the water line but above the sea floor.
