Portland (steam Tug)
''Portland'' (or the ''Portland'') is a sternwheel steamboat built in 1947 for the Port of Portland, Oregon, in the United States. The ''Portland'' is listed on the National Register of Historic Places, and presently hosts the Oregon Maritime Museum which owns the vessel. The vessel is moored at the Willamette River seawall next to Tom McCall Waterfront Park in downtown Portland. History ''Portland'' was built in 1947 and delivered to the Port of Portland on August 29 of that year. She was operated as a tug by both Willamette Tug & Barge and Shaver Transportation until she was retired in 1981. By that time, the Port of Portland was serving oil supertankers from Alaska that were too large for ''Portland'' to assist, and container ships with bow thrusting capabilities that reduced the need for tug assistance. Built at a time when steam paddlewheels were giving way to more modern propulsion systems, ''Portland'' was originally proposed as a diesel-powered screw-drive ...

Steel Bridge
The Steel Bridge is a through truss, double-deck vertical-lift bridge across the Willamette River in Portland, Oregon, United States, opened in 1912. Its lower deck carries railroad and bicycle/pedestrian traffic, while the upper deck carries road traffic (on the Pacific Highway West No. 1W, former Oregon Route 99W), and light rail (MAX), making the bridge one of the most multimodal in the world. It is the only double-deck bridge with independent lifts in the world and the second oldest vertical-lift bridge in North America, after the nearby Hawthorne Bridge. The bridge links the Rose Quarter and Lloyd District in the east to Old Town Chinatown neighborhood in the west. History The bridge was completed in 1912 and replaced the Steel Bridge that was built in 1888 as a double-deck swing-span bridge. The 1888 structure was the first railroad bridge across the Willamette River in Portland. Its name originated because steel, instead of wrought iron, was used in its construction, ...

Supertanker
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk cargo, bulk transport of petroleum, oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined petroleum, crude oil from its point of extraction to oil refinery, refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight tonnage, deadweight (DWT) to the mammoth ultra large crude carriers (ULCCs) of . Tankers move approximately of oil every year.UNCTAD 2006, p. 4.

Bonneville Dam
Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Lock and Dam is named for Army Capt. Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.

Cascade Locks, Oregon
Cascade Locks is a city in Hood River County, Oregon, United States. The city took its name from a set of locks built to improve navigation past the Cascades Rapids of the Columbia River. The U.S. federal government approved the plan for the locks in 1875, construction began in 1878, and the locks were completed on November 5, 1896. The locks were subsequently submerged in 1938, replaced by Bonneville Lock and Dam, although the city lost no land from the expansion of Lake Bonneville behind the dam some downstream of the city. The city population was 1,144 at the 2010 census. Cascade Locks is just upstream from the Bridge of the Gods, a toll bridge that spans the Columbia River. It is the only bridge across the Columbia between Portland and Hood River. Cascade Locks is a few miles upstream of Eagle Creek Gorge, a popular scenic area that doubles as an alternate route for the Pacific Crest Trail. Cascade Locks is used frequently by hikers along the Pacific Crest Trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawthorne Bridge
The Hawthorne Bridge is a truss bridge with a vertical lift that spans the Willamette River in Portland, Oregon, joining Hawthorne Boulevard and Madison Street. It is the oldest vertical-lift bridge in operation in the United States and the oldest highway bridge in Portland. It is also the busiest bicycle and transit bridge in Oregon, with over 8,000 cyclists and 800 TriMet buses (carrying about 17,400 riders) daily. It was added to the National Register of Historic Places in November 2012. Statistics The bridge consists of five fixed spans and one vertical-lift span. It is in total length. The bridge was originally wide, including two five-foot sidewalks, but the sidewalks were widened to 10 feet in 1998, increasing the structure's overall width to . The counterweights are suspended from the two towers. It is operated by a pair of 150-horsepower motors. On average, the lift span is raised for river traffic 120 times per month. While the river is at low level, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon Maritime Center And Museum
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness ...

Steam-powered
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
