Spread moorings are dominated by horizontal tension loads on which they rely to minimize the vessel’s horizontal response to wind, waves and current. recent floating wind activity involving a floating spar like structure will be moored by catenary lines. the hywind project in scotland, which consists of five 6 mw turbines, uses suction. Anchor types for floating energy facilities. acteon uses its moorings and anchors and foundation expertise to advise floating energy facility owners and operators in floating renewables and oil & gas on the options for anchoring their floating assets. one such example is this study performed for an asian developer.
A commonly used o&g drag anchor would be 10 12 tons, whereas it is between 35 40 tons for floating wind. no longer road transportable, it must be fabricated or assembled close to a suitable port facility. driven piles can be 2.0 3.0 meters in diameter and up to 15 20 meters in length, again difficult to transport, deliver and store. Watch acteon's webinar on practical and cost efficient mooring and anchoring solutions for floating wind. at present, 235 mw of floating wind energy has been harnessed globally. however, projections indicate an exponential surge to ten gigawatts by 2030. this would call for the deployment of an estimated 667 floating turbine platforms. Acteon’s expertise in mooring design and marine installation spans decades. we apply our deep domain expertise to help you choose the best options, from anchoring to cable laying to installation methods, to mitigate technical risks and lower the levellised cost of energy (lcoe). our experts’ views on the latest floating wind developments. Take aways. anchor selection is important! study options early. driven by local seabed conditions. more than one anchor type could be efficient across a wind farm. make sure design, procurement, installation and risk are all considered. logistics is critical due to space constraints and time. anchors are a significant portion of overall mooring.
