USAV Yaquina
USAV ''Yaquina'' is a Trailing suction hopper dredger, hopper dredge of the United States Army Corps of Engineers. Her primary mission is to maintain the entrance bars, rivers, and harbors along the coasts of California, Oregon, and Washington (state), Washington. She is assigned to the Portland District of the Army Corps of Engineers. Her homeport is Portland, Oregon. She was launched in 1980 and remains in service. Construction and characteristics In October 1977 the Army Corps of Engineers invited bids for a new hopper dredge of its own design. Bids were opened on December 15, 1977. Norfolk Shipbuilding and Drydock Corporation won the bid to build ''Yaquina'' at its Norfolk, Virginia shipyard. The initial contract price was $13,985,700. She was the first new dredge built by the United States government in 13 years.

Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada.

Dredge Yaquina, Corps Of Engineers In Morro Bay, CA
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

Willapa Bay
Willapa Bay () is a bay located on the southwest Pacific coast of Washington state in the United States. The Long Beach Peninsula separates Willapa Bay from the greater expanse of the Pacific Ocean. With over of surface area Willapa Bay is the second-largest riverine estuary on the Pacific coast of the continental United States. Early settlers called the bay Shoalwater Bay and this name is found on old maps and charts of the region. Willapa Bay is fairly shallow: more than half of its surface area lies in the intertidal zone, and half of the volume of water inside it enters and leaves with every tide. The bay is an estuary formed when the Long Beach Peninsula, a long sand spit from the Columbia River to the south, partially enclosed the estuaries of several smaller rivers. It is a ria, which formed after the rise in sea level at the end of the last ice age flooded several small river valleys. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manoeuvring Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
