Each leg is also sub-divided along its length into compartments a third of the way from each end which act as independent water-tight compartments. Experience. There are five main types of fixed platform, ranging from the conventional fixed platform used at depths of up to 150m, to the tension leg platform that can be used at depths of 2000m. [7] 4 [3], The four legs are joined by a "chord shortener" (not present in the picture at right), a reinforced concrete box connecting the legs that damps out any potentially destructive wave-leg resonances by retuning the legs' natural frequencies. The base is a Condeepgravity base structurebuilt from reinforced concrete. Troll A is one of the biggest and most complex engineering projects ever undertaken, and remains the tallest and heaviest structure ever moved into another position. The platform was complete with its 22,000t topside 150m above the sea level during tow out and installed at 303 m water depth in the North Sea in 1995. When our platform becomes too narrow for people of all creeds and of no creeds, I myself cannot stand upon it.”—Susan B. Anthony (1820–1906).
