Dolphin (structure)
A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids. Structure Dolphins typically consist of a number of piles driven into the seabed or riverbed, and connected above the water level to provide a platform or fixing point. The piles can be untreated or pressure treated timber piles, or steel or reinforced concrete piles. Smaller dolphins can have the piles drawn together with wire rope, but larger dolphins are typically fixed using a reinforced concrete capping or a structural steel frame. Access to a dolphin may be via a pedestrian bridge, particularly in the case of mooring dolphins, but is often by boat. Use As mooring point Dolphins are usually installed to provide a fixed structure when it would be impractical to extend the shore to provide a dry- ...

Berth (moorings)
A berth is a designated location in a port or harbour used for mooring vessels when they are not at sea. Berths provide a vertical front which allows safe and secure mooring that can then facilitate the unloading or loading of cargo or people from vessels. Locations in a port Berth is the term used in ports and harbors for a designated location where a vessel may be moored, usually for the purposes of loading and unloading. Berths are designated by the management of a facility (e.g., port authority, harbor master). Vessels are assigned to berths by these authorities. Most berths are alongside a quay or a jetty (large ports) or a floating dock (small harbors and marinas). Berths are either general or specific to the types of vessel that use them. The size of the berths varies from for a small boat in a marina to over for the largest tankers. The rule of thumb is that the length of a berth should be roughly 10% longer than the longest vessel to be moored at the berth. Ber ...

Fender (boating)
In boating, a fender is a bumper used to absorb the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel. Fenders, used on all types of vessels, from cargo ships to cruise ships, ferries and personal yachts, prevent damage to vessels and berthing structures. To do this, fenders have high energy absorption and low reaction force. Fenders are typically manufactured out of rubber, foam elastomer or plastic. Rubber fenders are either extruded or made in a mold. The type of fender that is most suitable for an application depends on many variables, including dimensions and displacement of the vessel, maximum allowable stand-off, berthing structure, tidal variations and other berth-specific conditions. The size of the fender unit is based on the berthing energy of the vessel which is related to the square of the berthing velocity. Historically, fenders were knotted from rope in a variety of patterns and shapes. Often damaged lines would be used for t ...

Starling (structure)
In architecture, a starling (or sterling) is a defensive bulwark, usually built with pilings or bricks, surrounding the supports (or piers) of a bridge or similar construction. Starlings may be shaped to ease the flow of the water around the bridge, reducing the damage caused by erosion or collisions with flood-borne debris, and may also form an important part of the structure of the bridge, spreading the weight of the piers. The term cutwater is used for such a structure shaped with water flow in mind, as a pier or starling with a diamond point. A starkwater is a bulwark against ice floes. Depending on their shape and location, some starlings may accumulate river debris, mud and other objects, potentially creating navigational hazards or hindering downstream water flow. Shape Starlings may form part of a buttress for the vertical load of the bridge piers, and for that purpose would typically be symmetrical. Examples such as at the Old Wye Bridge, Chepstow are on lower stretc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daybeacon
A day beacon (sometimes "daybeacon") is an unlighted nautical sea mark. A signboard identifying it is called a day mark. Day beacons typically mark channels whose key points are marked by lighted buoys. They may also mark smaller navigable routes in their entirety. They are the most common navigation aid in shallow water, as they are relatively inexpensive to install and maintain. Navigation around them is similar to that around other navigation aids. Identification Lateral marking For historical reasons, there are two systems for lateral day beacons. When proceeding from open water towards harbor, marks with cylindrical topmarks or square dayboards are kept to port in both regions, but colors and numbers are reversed. When lateral beacons are paired, vessels should pass between the pairing. However, beacons are also frequently placed individually. Generally, single lateral beacons are at the inside corner of a turn. Interior or exterior placement can be determined based u ...

The Orlando Sentinel
The ''Orlando Sentinel'' is the primary newspaper of Orlando, Florida, and the Central Florida region. It was founded in 1876 and is currently owned by Tribune Publishing Company. The ''Orlando Sentinel'' is owned by parent company, ''Tribune Publishing''. This company was acquired by Alden Global Capital, which operates its media properties through Digital First Media, in May 2021. The newspaper's website utilizes geo-blocking, thus making it unaccessible from European countries. History The ''Sentinel''s predecessors date to 1876, when the ''Orange County Reporter'' was first published. The ''Reporter'' became a daily newspaper in 1905, and merged with the ''Orlando Evening Star'' in 1906. Another Orlando paper, the ''South Florida Sentinel'', started publishing as a morning daily in 1913. Then known as the ''Morning Sentinel'', it bought the ''Reporter-Star'' in 1931, when Martin Andersen came to Orlando to manage both papers. Andersen eventually bought both papers outright ...

MV Summit Venture
The MV ''Summit Venture'' was a bulk carrier that is best known for colliding into the Sunshine Skyway Bridge in 1980. It was built in 1976 by Oshima Shipbuilding Co. of Nagasaki, Japan. She was long, had a breadth of , deadweight of 33,912 tons, gross weight of 19,735 tons and a net weight of 13,948 tons. After being repaired from colliding into the Sunshine skyway bridge it would go through several different owners. It would sink off Vietnamese coast in 2010 under the name of ''Jian Mao 9''. 1980 incident ''Summit Venture'' was involved in a fatal collision with the original Sunshine Skyway Bridge in Tampa Bay, Florida, on May 9, 1980. While negotiating a required turn in the narrow channel during a storm, the radar failed, and the freighter struck one of the piers on the southbound span of the bridge. of the steel cantilever highway bridge collapsed, causing a Greyhound bus, a truck, and six other vehicles to fall into the bay. A total of 35 people died. The pilot of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tampa Bay
Tampa Bay is a large natural harbor and shallow estuary connected to the Gulf of Mexico on the west-central coast of Florida, comprising Hillsborough Bay, McKay Bay, Old Tampa Bay, Middle Tampa Bay, and Lower Tampa Bay. The largest freshwater inflow into the bay is the Hillsborough River, which flows into Hillsborough Bay in downtown Tampa. Many other smaller rivers and streams also flow into Tampa Bay, resulting in a large watershed area. The shores of Tampa Bay were home to the Weedon Island Culture and then the Safety Harbor culture for thousands of years. These cultures relied heavily on Tampa Bay for food, and the waters were rich enough that they were one of the few Native American cultures that did not have to farm. The Tocobaga was likely the dominant chiefdom in the area when Spanish explorers arrived in the early 1500s, but there were likely smaller chiefdoms on the eastern side of the bay which were not well documented. The indigenous population had been decimated b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunshine Skyway Bridge
The Bob Graham Sunshine Skyway Bridge, often referred to as the Sunshine Skyway Bridge or the Sunshine Skyway, consists of a pair of long beam bridges with a central cable-stayed bridge that spans Lower Tampa Bay to connect St. Petersburg, Florida to Terra Ceia. The current Sunshine Skyway opened in 1987 and is the second bridge of that name on the site. It was designed by the Figg & Muller Engineering Group and built by the American Bridge Company. The bridge is considered the flagship bridge of Florida and serves as a gateway to Tampa Bay. The four-lane bridge carries Interstate 275 and U.S. Route 19, passing through Pinellas County, Hillsborough County and Manatee County. It is a toll road, with a $1.50 toll assessed on two-axle vehicles traveling in either direction and collected via cash or the state's SunPass system. The original Sunshine Skyway was a two-lane beam bridge with a central truss bridge built directly to the west of the current structure. It was completed ...

Mooring (watercraft)
A mooring is any permanent structure to which a vessel may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An ''anchor mooring'' fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, ''mooring'' refers to the act of attaching a vessel to a mooring. The term likely stems from the Dutch verb ''meren'' (to ''moor''), used in English since the end of the 15th century. Permanent anchor mooring These moorings are used instead of temporary anchors because they have considerably more holding power, for example because of lesser damage to the marine environment, and are convenient. Where there is a row of moorings they are termed a tier. They are also occasionally used to hold floating docks in place. There are several kinds of moorings: Swing moorings Swing moorings also known a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skyway Bridge Old And New
A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of enclosed or covered footbridges that protect pedestrians from the weather. Open-top modern skyways in mountains now often have glass bottoms. Sometimes enclosed urban skywalks are made almost totally from glass, including ceilings, walls and floors. Also, some urban skyways function strictly as linear parks designed for walking. In North America skyways are usually owned by businesses, and are therefore not public spaces (compare with sidewalk). However, in Asia, such as Bangkok's and Hong Kong's skywalks, they are built and owned separately by the city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers. Skyways usually connect on the first few floors above the ground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
