Here are the 15 Most Magnificent Engineering Technologies in The World
1) Largest Flood Defence
The Delta Works off the coast of Holland is a huge series of dams, locks, sluices, storm surge barriers and dokes designed to protect low-lying areas of the country from the sea. Construction began in 1950 and ended in 1997 with the completion of the Maeslantkering and the Hartelkering barriers. The Delta Works contain some 16,495 km (10,250 miles) of dikes and around 300 structures.
2) Largest Man-Made Excavation
The Bingham Canyon Copper Mine near Salt Lake City, Utah, USA, is the world’s largest man-made excavation. More than 5.4 billion tonnes (15.9 billion tons) of rock have been excavated from it since 1906. Visible from space, it measures 4 km (2.5 miles) across and 1.2 km (0.75 miles) deep and has been called “the richest hole on Earth”. In 2001, more than 15.4 million tonnes (16.9 million tons) of copper have been produced from the mine, as well as 652 million g (23 million oz) of gold and 5.3 billion g (190 million oz) of silver.
3) Heaviest Weight Lifted by Crane
A barge, ballasted with water and weighing a hefty 20,133 tonnes (44,385,667 lb), was lifted by the “Taisun” crane at Yantai Raffles Shipyard, Yantai, China, on 18 April 2008.
4) Longest Drilled Oil Well
The world’s longest drilled oil well is BD-04-A, with a total length of 12,289 m (40,320 ft). It was completed in May 2008 by Maersk Oil Qatar and Qatar Petroleum, in the Al-Shaheen offshore oil field off the coast of Qatar. The well includes a horizontal section measuring 10,902 m (35,790 ft).
