2017年8月15日 · The dry cured concrete U.S. Spar Buoy and associated ocean-going deck barge, with its own propulsion, are revolutionary approaches to greatly reduce offshore WTG capital and O&M cost.

2024年12月5日 · The Spar-Buoy is the most widely adopted floating wind turbine foundation due to its proven stability and suitability for deep waters (>100 m), where early floating wind projects have focused. Its simple, robust design ensures minimal motion under harsh offshore conditions, making it reliable for pilot and commercial projects like Hywind Scotland.

2019年4月26日 · Current offshore wind turbines are typically assembled by lifting and bolting standard onshore towers and wind turbine generators (WGT) onto a purpose designed floater. The concept presented here proposes to integrate the tower section and the floater at the fabrication yard while in horizontal position.

substructure (spar buoy) and a large offshore WTG. The units are stationed approximately 1,000 meters (3,300 feet) apart to minimize the wind-shadow effect. Each 6 MW WTG stands 656 feet above the mean sea level. The FOWS will maintain station-keeping via six synthetic ropes tethered to three anchors on the ocean floor. MATERIAL IMPROVEMENTS

2022年7月1日 · Three 20 MW spar floating wind turbines are designed, with varying static thrust at rated wind. The entire structure is modeled as flexible, with potential-theory loads distributed over the hull. “Detuned” control systems are inadequate for large FWTs, thus a motion compensation approach is adopted.

2021年8月27日 · A qualitative comparison between semi-submersible, spar, and TLP, the three most popular types of floating wind foundations, is presented from various perspectives, including design, fabrication and transportation and installation (T&I);

2017年8月8日 · The present invention provides a system which facilitates the construction and installation of a spar buoy foundation for offshore wind turbine generator (“WTG”) units. The tension leg...

2017年5月19日 · The MACC spar buoy and associated ocean-going deck barge are revolutionary approaches to greatly reduce offshore WTG capital and O&M cost. From the new material selection, which enables novel fabrication techniques in the offshore industry, to the unique barge enabling simplified transportation and WTG deployment logistics, these advances ...

2023年5月3日 · Floater structures are designed to support the operation of the wind turbine generators (WTG) and associated electrical infrastructure while maintaining stability and resisting the environmental and WTG loading applied for the entire life of the structure.
