Get premium, high resolution news photos at Getty Images Troll A was built by Norwegian Contractorsfor Norske Shell, with base construction beginning in July 1991. Built from reinforced concrete, as of 2014[update], it was the tallest and heaviest structure that has ever been moved to another position, relative to the surface of the Earth, and is among the largest and most complex engineering projects in history. Other readers will always be interested in your opinion of the books you've read. Each leg is a mathematically joined composite of several conical cylinders that flares out smoothly to greater diameters at the top and bottom, so each support is somewhat wasp-waisted when viewed in profile and circular in any cross-section (see picture at right). Company Owner Lone Star Alloys February 2019 – Present 8 months. 6 and Fig. As a result Troll-A’s natural gas deliveries to Europe, via an onshore processing plant, has increased from 85 million cubic meters prior to the pre-compression to 110 million cubic meters now, constituting nearly 15% of entire European daily usage. 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. [1] The platform was a televised sensation when it was towed into the North Sea in 1996, where it is now operated by Equinor. Troll A platform being towed out of a Norwegian fjord. The new control room and expanded facilities are needed to support the new compressors (a third and fourth are planned and being installed in 2014). The Troll A platform was built using 100,000t of steel and 245,000m³ of concrete. The Troll A platform is a condeep offshore natural gas platform in the Troll gas field off the west coast of Norway. It is the tallest and heaviest structure that has ever been moved to another position, relative to the surface of the Earth, and is among the largest and most complex engineering projects in history. The legs use groups of six 40 metres (130 ft) tall vacuum-anchors holding them fixed in the mud of the sea floor.[3]. The Troll A platform is a condeep offshore natural gas platform in the Troll gas field off the west coast of Norway. The Troll A platform is an offshore natural gas platform in the Troll gas field off the west coast of Norway. An oil platform, offshore platform, or offshore drilling rig is a large structure with facilities for well drilling to explore, extract, store, and process petroleum and natural gas that lies in rock formations beneath the seabed. Also as a result, Troll-A platform … It is the tallest construction that has ever been moved to another position, relative to the surface of the Earth, and is among the largest and most complex engineering projects in history. Timpson High School 1993 – 2006. In 1996, the platform set the Guinness World Record for 'largest offshore gas platform'. The Troll A platform is a condeep offshore natural gas platform in the Troll gas field off the west coast of Norway. The “simple” solution is to build a very tall caisson which reaches to the surface and is open air, so the interior is always at one atmosphere. Experience. The project started in 1991, and was concluded in 1996.

The Troll A platform has an overall height of 472 metres (1,549 ft), weighs 683,600 tons (1.2 million tons with ballast), standing on the sea floor 303 metres (994 feet) below the surface of the sea. Many oil platforms will also contain facilities to accommodate their workforce. [7] A158-00251: Troll A platform built by Norwegian Contractors for Norske Shell, Norway, North Sea. The base is a Condeep gravity base structure built from reinforced concrete. Located about 80 km off the west coast of Norway is Troll A, a colossal natural gas platform and the tallest structure ever moved by mankind. After nine years’ operation it became necessary to boost production by installing two compressors on the immense Troll A platform. Troll A was built by Norwegian contractors for Norske Shell, and the entire project cost $650 million USD. At 1.2 million ton ballasted under tow, 472 meters high, with underwater concrete structure at 369 meters, and dry weight of 656,000 tons, the Troll A platform is a majestic piece of design and construction. Moving appliances, boxes and furniture is a tough job; these tools make it easier. [3], The legs must be able to withstand intense pressures, so the walls of Troll A's legs are over 1 metre thick and are made of steel-reinforced concrete that was formed in one continuous pour – a lengthy process that takes 20 minutes per 5 cm laid. [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 Troll A platform is a condeep offshore natural gas platform in the Troll gas field off the west coast of Norway. Probably the most impressive Condeep is the Troll A platform, shown in Fig. It is located in the Norwegian Troll gas field in the North Sea.With a total height of 472 meters, and a subsea structure of concrete measuring 369 meters, it is the highest concrete platform ever constructed for the oil and gas sector. Inside view Troll Platform’s Leg. Gas rises from 40 wells and is exported through a number of pipes to a processing plant at Kollsnes. 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. The concert set a new world record for the deepest underwater concert, at 303 metres (994 ft) below sea level. ABB provided these devices with a revolutionary solution. In the autumn of 2010 the Troll A platform was expanded with a new module.
