What is a fixed platform?
A fixed platform is a permanent structure connected to the ocean floor, often for drilling oil at sea. Most of the workspace of such a platform is increased above the sea of solid steel or concrete supports. This distinguishes a fixed platform from mobile platforms that float on the sea surface and are anchored to the Ocean DNA by more or less flexible berths. Fixed platforms are usually deployed in water less than 1700 feet (520 meters) deep, with deeper drilling operations require more complex mobile sets. In 1947, the first fixed drilling set on the platform was built in the Gulf of Mexico, located behind the view of the attic. The repaired platforms were mostly the most common way of drilling at sea for most of the 20th century, although the first Wovodoz mobile drilling trains to the early 1930s. Due to their high degree of stability, deep limitation and high costs, modern fixed platform sets are limited to long -term drilling operations in shallow water.
solid platforms are directly connected to the ocean bottom by a structural support known as a jacket. The first jackets consisted of concrete pillars, while modern deep waters jackets are complex tubular steel support towers. The jacket base can be several times wider than the upper part and are often blown deep into the mud of the ocean DNA for support. The jackets are partially or completely designed on the coast and supplied to place the platform on tugged boats. Once they are there, they are lowered into the ocean bottom using straight and travel to the place using drivers of a pile mounted on a boat.
Thedecks that make up the platform workspace are generally designed in shipyards or sheperred bays. While the early decks were towed to the place on the boats, many modern packages are built to float during the transit. Are raised on top of the waiting jacket using hydraulic connectors or crane systemsBlocks and are usually set enough highly above the horizontal to avoid all the greatest waves. The decks can be up to 200 feet (60 meters) across and consist of several levels of work and residential areas.
If a fixed platform is near the coast, pumping oil can directly from the bore point to the storage device on the mainland across the pipeline along the ocean bottom. In the case of drilling operations, the platform must contain large storage tanks that hold oil until it can be transferred to the oil tanker. The storage tanks are often placed under the water line, where they serve as a load to help the platform to withstand the power of waves and streams.
