Biscay Marine Energy Platform
The Biscay Marine Energy Platform (BiMEP) is a renewable energy test site located in the Bay of Biscay off the coast of the Basque Country, Spain. It is publicly funded, 75% by the Basque Energy Agency (, , EVE), and 25% by the Spanish Government's Institute for the Diversification and Saving of Energy (, IDAE). The main offshore test site is located north of Armintza, Bizkaia, about north of Bilbao. This has four pre-consented test berths, each with a 5 MW grid connection. BiMEP also manages the Mutriku Breakwater Wave Plant in Mutriku, about east along the coast. Several wave power concepts, or wave energy converters (WEC) and a floating wind turbine have been tested at BiMEP. It is also home to the Harshlab offshore materials testing platform. BiMEP offshore test site The offshore test site encompasses an area of located offshore, with water depths of . It contains four test berths, each with a 5 MW three-phase electrical cable operating at 13.2 kV co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wave Power
Wave power is the capture of energy of wind waves to do useful mechanical work, work – for example, electricity generation, desalination, or pumping water. A machine that exploits wave power (physics), power is a wave energy converter (WEC). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations, and other factors. As long as the waves propagate slower than the wind speed just above, energy is transferred from the wind to the waves. Air pressure differences between the windward and leeward sides of a wave crest (physics), crest and surface friction from the wind cause shear stress and wave growth. Wave power as a descriptive term is different from tidal power, which seeks to primarily capture the energy of the current caused by the gravitational pull of the Sun and Moon. However, wave power and tidal power are not fundamentally distinct and have significant cross-over in technology and implementation. Other forces ...

Spar Buoy
A spar buoy is a tall, thin buoy that floats upright in the water and is characterized by a small water plane area and a large mass. Because they tend to be stable ocean platforms, spar buoys are popular for making oceanographic measurements. Adjustment of the water plane area and the mass allows spar buoys to be tuned so they tend to not respond to wave forcing. This characteristic differentiates them from large water plane area buoys such as discus buoys that tend to be wave followers. Spar buoys are often used as stable platforms for wave measurement devices and air–sea interaction measurements. Spar buoys range in length from around one metre to the RP FLIP. To avoid the difficulties inherent with shipboard launch and recovery, helicopter deployment of large spar buoys has been studied. See also *Spar (platform) A spar is a marine structure, used for floating oil platform, oil/gas platforms. Named after navigation channel Spar buoys, spar platforms were developed as an e ...

Bay Of Biscay
The Bay of Biscay ( ) is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarc'h to the Spanish border, and along the northern coast of Spain, extending westward to Cape Ortegal. The average depth is and the greatest depth is . Etymology The Bay of Biscay is known in Spain as the Gulf of Biscay (; ). In France, it is called the Gulf of Gascony ( ; ; ; ). In Latin, the bay was known as ( Cantabrian Gulf); the name Cantabrian Sea is still used locally for the southern area of the Bay of Biscay that washes over the northern coast of Spain ( Cantabria). The English name comes from Biscay on the northern Spanish coast, probably standing for the western Basque districts (''Biscay'' up to the early 19th century). Geography Parts of the continental shelf extend far into the bay, resulting in fairly shallow waters in many areas and thus the rough seas for which the region is known. Heavy storms ...

Electrical Grid
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the ''power grid''. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same ...

Seabed
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as seabeds. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates mid-ocean ridges along the center line of major ocean basins, where the seabed is slightly shallower than the surrounding abyssal plain. From the abyssal plain, the seabed slopes upward toward the continents and becomes, in order from deep to shallow, the continental rise, Continental slope, slope, and Continental shelf, shelf. The depth within the seabed itself, such as the depth down through a sediment core, is known as the "depth below seafloor". The ecological environment of the seabed and the deepest waters are collectively known, as a habitat for creatures, as the "benthos". Most of the seabed throughout the world's oceans is covered in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Front-End Engineering And Design
Front-end loading (FEL), also referred to as Front-End Engineering Design (FEED), Front End Planning (FEP), pre-project planning (PPP), and early project planning, is the process for conceptual development of projects in processing industries such as upstream oil and gas, petrochemical, natural gas refining, extractive metallurgy, waste-to-energy, biotechnology, and pharmaceuticals. This involves developing sufficient strategic information with which owners can address risk and make decisions to commit resources in order to maximize the potential for success. ''Front-end loading'' includes robust planning and design early in a project's lifecycle (i.e., the ''front end'' of a project), at a time when the ability to influence changes in design is relatively high and the cost to make those changes is relatively low. It typically applies to industries with highly capital intensive, long lifecycle projects (i.e., hundreds of millions or billions of dollars over several years before ...

Wave Energy Converters
In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities. '' Periodic waves'' oscillate repeatedly about an equilibrium (resting) value at some frequency. When the entire waveform moves in one direction, it is said to be a travelling wave; by contrast, a pair of superimposed periodic waves traveling in opposite directions makes a ''standing wave''. In a standing wave, the amplitude of vibration has nulls at some positions where the wave amplitude appears smaller or even zero. There are two types of waves that are most commonly studied in classical physics: mechanical waves and electromagnetic waves. In a mechanical wave, stress and strain fields oscillate about a mechanical equilibrium. A mechanical wave is a local deformation (strain) in some physical medium that propagates from particle to particle by creating local stresses that cause strain in neighboring particles too. For ...
