Equinor Lines Up Floating Wind in S.Korea

Korea's state-owned National Oil Corporation (KNOC) will explore opportunities to develop commercial floating offshore wind farms in South Korea, the Norwegian company said on Friday.South Korea aims to reduce its dependence on nuclear and coal power, targeting an increase in the share of renewable energy to 20 percent by 2030, compared with 7.6 percent in 2017, the country said last year.Equinor says this translates to a target of 49 gigawatts (GW) of new generation capacity.KNOC plans to develop a 200 MW floating offshore wind project 58 km off the coast of Ulsan City, the Norwegian company added

Contemporary UUV Propulsor Design

From the standpoint of vehicle propulsion physics, an unmanned underwater vehicle (UUV) is little different from your personal ski boat or a tanker. It shares the Vessel-Propulsor-Drive system model, which allows a Propulsor to convert Drive energy into thrust for the purpose of moving a Vessel. The basic principles of thrust equilibrium and motion are common to all three, as are the translation of rotational energy into axial thrust by the central element of the system – the Propulsor.Not shared by different vehicle types are the constraints and design objectives that are unique to each vehicle&r

turns for undersea positioning purposes.Commercially Hugin, and its competitors, are serving numerous markets. Military buyers use AUVs for mine hunting and physical oceanography. Science users search for shipwrecks and hydrothermal vents. But the most vibrant commercial sector for AUVs is in offshore energy. Both oil and gas and renewables such as offshore wind employ AUVs for many different types of mission from site characterization & inspection to pipeline inspection. Marine hydrography and 3D pseudo-seismic as well as archaeological studies are also common commercial applications. Today the

;sway” turns, whereby it can rapidly move in a lateral direction without having to turn the entire vessel. Instead of having to turn one or more long hulls of a conventional monohull or catamaran, the short individual hulls are far more maneuverable and can be rotated quickly and with less energy. The design is also lightweight and minimalist, further contributing to performance and maneuverability.To rotate the hulls each of the four 300hp outboard motors are turned using a drive by wire control system.

He was 101.As a geophysicist at Scripps Institution of Oceanography at the University of California San Diego, Munk made groundbreaking observations of waves, ocean temperature, tidal energy in the deep ocean, ocean acoustics and the rotation of the earth. As an advocate of science and broader scholarship, Munk served as an advisor to presidents and the Pentagon and conferred with public figures including the Dalai Lama and Pope Francis. His convictions led him to refuse to sign a loyalty

Kvaerner to Study Floating Wind Structures

Norway based Kvaerner said it has signed a contract with Norwegian energy company Equinor to study how floating concrete substructures for offshore wind turbines can be designed and constructed for the planned Hywind Tampen project in the North Sea.The objectives of the front-end engineering and design (FEED) assignment are to further mature the design of the concrete substructures, to identify appropriate construction site(s), and to develop a plan for construction, method and cost for production of 11 floating concrete substructures, Kvaerner said.“Another important part of the FEED contract

European Offshore Wind Capacity up 18%

Europe installed 2.6 GW of new offshore wind energy capacity in 2018, according to statistics released by the European Wind Energy Association, WindEurope. That translates to a 18% increase in Europe’s offshore wind capacity.According to WindEurope, 15 new offshore wind farms came on line. The UK and Germany accounted for 85% of the new capacity: 1.3 GW and 969 MW respectively.Europe now has 105 offshore wind farms across 11 countries with a total capacity of 18.5 GW. This is around 10% of the total installed wind energy capacity in Europe – the rest is onshore.The size and scale of
