A man built megasooruzhenie oil and gas - a gas platform Troll-A. This is one of the world's largest gas platforms, the giant of the North Sea. Within this structure is hidden a lot of innovation to prevent the disaster. This building is not only a magnificent engineering marvel, but the largest object ever moved by man across the surface of the Earth.


For the stability of the platform was half submerged, but the remaining part of the water is impressive. Then a few tugs for 7 days Troll transported to the place of its future performance. Usually support the platform is transported separately, and then - supported by special ships into place. In the case of Troll-A, however, the entire platform was assembled in one location, and then moved out to sea. Platform towed more than 200 miles from the northern region Vatsa Rogaland, for Troll field, 80 kilometers north-west of Bergen. Towing took seven days. The platform is on the seabed at 303 meters below the sea surface. In one of the pillars of concrete cylindrical elevator that delivers nine minutes personnel and technicians to the seabed. Troll wall supports more than 1 meter thick made of steel reinforced concrete formed in one continuous stream. The four racks attached concrete box, connecting them, which has a special function damping unwanted resonances potentially devastating earthquake and waves. Each support is also divided along its length by independent watertight compartments. Uses a group of six 40-meter vacuum anchors holding the installation on the seabed.










In 1996, the platform has established mirovoyrekord got into the Guinness Book of Records as "the largest offshore gas platform '. That title now belongs to the Petronius Platform in the Gulf of Mexico, which rises to 610 meters above the ocean floor. For comparison, the size of the platform and the famous sights of Paris, the Eiffel Tower:
