An oil platform is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform linked by bridge to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed to the ocean floor, consist of an artificial island, or float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells.
The Troll A platform is a Condeep gravity-based structure offshore natural gas platform in the Troll gas field off the west coast of Norway. Built from reinforced concrete, as of 2014, it was the tallest 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 platform was a televised sensation when it was towed into the North Sea in 1995, where it is now operated by Equinor. It is also the heaviest object moved and the object with the second highest displacement at 1.2 million tons(the object with the highest displacement is the Gullfaks C, which had a displacement approaching 1.5 million tons). Troll A was towed from the afternoon 10 May 1995 until the platform was in place 17 May 1995. It was lowered to the seabed in 303 meters of water, and had penetrated 36 meters into the soil by 19 May 1995. It was self-supporting with no further mooring required.
The Peak Tram is a funicular railway in Hong Kong, which carries both tourists and residents to the upper levels of Hong Kong Island. Running from Garden Road Admiralty to Victoria Peak via the Mid-Levels, it provides the most direct route and offers good views over the harbour and skyscrapers of Hong Kong. Operated since 1888, it was the first funicular railway in Asia.
Tallinn TV Tower is a free-standing structure with an observation deck, built to provide better telecommunication services for the 1980 Moscow Summer Olympics regatta event. It is located near the suburb Pirita, six km north-east of the Tallinn city center. With its 313 m (1030.2 ft), the TV tower is the tallest nonbuilding structure in Tallinn. The tower was officially opened on 11 July 1980. The viewing platform at a height of 170 metres was open to the public until 26 November 2007, when it was closed for renovation. The tower began receiving visitors again on 5 April 2012. The building is administered by the public company Levira and is a member of the World Federation of Great Towers.
Petergof, known as Petrodvorets (Петродворец) from 1944 to 1997, is a municipal town in Petrodvortsovy District of the federal city of St. Petersburg, located on the southern shore of the Gulf of Finland.
A load-bearing wall or bearing wall is a wall that is an active structural element of a building, which holds the weight of the elements above it, by conducting its weight to a foundation structure below it.
A tension-leg platform (TLP) or extended tension leg platform (ETLP) is a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 metres and less than 1500 metres. Use of tension-leg platforms has also been proposed for offshore wind turbines.
The Florianturm is a telecommunications tower and landmark of Dortmund (Germany). It is named after St. Florian, the patron saint of gardeners.
The Jeita Grotto is a system of two separate, but interconnected, karstic limestone caves spanning an overall length of nearly 9 kilometres (5.6 mi). The caves are situated in the Nahr al-Kalb river valley within the locality of Jeita, 18 kilometres (11 mi) north of the Lebanese capital Beirut. Though inhabited in prehistoric times, the lower cave was not rediscovered until 1836 by Reverend William Thomson; it can only be visited by boat since it channels an underground river that provides fresh drinking water to more than a million Lebanese.
The Big Pineapple is a heritage-listed tourist attraction and big thing at Nambour Connection Road, Woombye, Sunshine Coast Region, Queensland, Australia. It was designed by Peddle Thorp and Harvey, Paul Luff, and Gary Smallcombe and Associates. It is also known as Sunshine Plantation. It was added to the Queensland Heritage Register on 6 March 2009.
Journey Behind the Falls is an attraction in Niagara Falls, Ontario, Canada located in the Table Rock Centre beside the Canadian Horseshoe Falls. It is open year round and run by the Niagara Parks Commission.
Weather buoys are instruments which collect weather and ocean data within the world's oceans, as well as aid during emergency response to chemical spills, legal proceedings, and engineering design. Moored buoys have been in use since 1951, while drifting buoys have been used since 1979. Moored buoys are connected with the ocean bottom using either chains, nylon, or buoyant polypropylene. With the decline of the weather ship, they have taken a more primary role in measuring conditions over the open seas since the 1970s. During the 1980s and 1990s, a network of buoys in the central and eastern tropical Pacific Ocean helped study the El Niño-Southern Oscillation. Moored weather buoys range from 1.5–12 metres (5–40 ft) in diameter, while drifting buoys are smaller, with diameters of 30–40 centimetres (12–16 in). Drifting buoys are the dominant form of weather buoy in sheer number, with 1250 located worldwide. Wind data from buoys has smaller error than that from ships. There are differences in the values of sea surface temperature measurements between the two platforms as well, relating to the depth of the measurement and whether or not the water is heated by the ship which measures the quantity.
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas.
Langkawi Sky Bridge is a 125-metre (410 ft) curved pedestrian cable-stayed bridge in Malaysia, completed in 2005.

The Peterhof Palace is a series of palaces and gardens located in Petergof, Saint Petersburg, Russia, commissioned by Peter the Great as a direct response to the Palace of Versailles by Louis XIV of France. Originally intending it in 1709 for country habitation, Peter the Great sought to expand the property as a result of his visit to the French royal court in 1717, inspiring the nickname of "The Russian Versailles". The architect between 1714 and 1728 was Domenico Trezzini, and the style he employed became the foundation for the Petrine Baroque style favored throughout Saint Petersburg. Also in 1714, Jean-Baptiste Alexandre Le Blond, likely chosen due to his previous collaborations with Versailles landscaper André Le Nôtre, designed the gardens. Francesco Bartolomeo Rastrelli completed an expansion from 1747 to 1756 for Elizabeth of Russia. The palace-ensemble along with the city center is recognized as a UNESCO World Heritage Site.
Júlio Prestes is a train station on ViaMobilidade Line 8-Diamond, located in the district of Santa Cecília in São Paulo. This historical station was named after former Governor of São Paulo and former President-elect of Brazil, Júlio Prestes. Currently, the station attends only the Line 8-Diamond.

It was added to the Queensland Heritage Register on 21 August 1992. The railway is used to operate a tourist rail service, the Kuranda Scenic Railway. It forms part of the Tablelands railway line.
The geology of Croatia has some Precambrian rocks mostly covered by younger sedimentary rocks and deformed or superimposed by tectonic activity.
Offshore embedded anchors are anchors intended for offshore use that derive their holding capacity from the frictional, or bearing, resistance of the surrounding soil, as opposed to gravity anchors, which derive their holding capacity largely from their weight. As offshore developments move into deeper waters, gravity-based structures become less economical due to the large size needed and the consequent cost of transportation.
