A fixed platform is a type of offshore platform used for the extraction of petroleum or gas. These platforms are built on concrete and/or steel legs anchored directly onto the seabed, supporting a deck with space for drilling rigs, production facilities and crew quarters. Such platforms are, by virtue of their immobility, designed for very longterm use. ⌛ Various types of structure are used, steel jacket, concrete caisson, floating steel and even floating concrete. #OffshorePlatform #PetroleumExtraction #EngineeringMarvel

Steel jackets are vertical sections made of tubular steel members, and are usually piled into the seabed. #EngineeringMarvels #UnderwaterStructures

Fixed platforms are economically feasible for installation in water depths up to about 500 feet (150 m); for deeper depths a floating production system, or a subsea pipeline to land or to shallower water depths for processing, would usually be considered . #OilAndGas #Energy #Engineering
