The Intelligent Moorings project **"**Quarter Scale Testing of the Intelligent Mooring System for Floating Offshore Wind Platforms" is a joint UK and US collaborative project comprising Intelligent Moorings, the University of Exeter, PCCI, Inc, and Ocergy Inc together with a range of further support from the ORE Catapult, the US Navy and NREL.Intelligent Moorings is developing the IMS load reduction mooring systems based on pressurised rope technology, the University of Exeter provide modelling and the Dynamic Marine Component Test Facility (DMaC), PCCI are bespoke moorings specialists managing the sea trial deployment, Ocergy will provide platform interface support and end user feedback, the US Navy provide the WETS test facility, the ORE Catapult LCOE studies, NREL data acquisition and ABS Product Design Assessment and Certification support.The project undertakes coupled modelling, interfaces with platform design requirements and scales up an existing IMS design to meet quarter scale loads for the NREL 15MW reference turbine. It designs and builds an IMS system for deployment and test at the US Navy WETS test site to prove the operational performance of the IMS system can deliver significant LCOE reductions.Mooring systems are critical sub-systems for floating installations, warranting safe station keeping and hydrodynamic stability. The moorings must withstand ultimate load conditions, as well as cyclic fatigue loading. Floating installations in water depths exceeding 50m will be required to access much of the global offshore wind resource. Conventional mooring designs rely on adaptations from the oil and gas sector that can meet the required integrity and safety margins but lead to CAPEX intensive designs. The capital cost of moorings is driven by extreme (peak load) conditions, whilst revenue is generated under normal operating conditions. If peak loads can be mitigated, the cost of mooring systems and associated structural elements, as well as deployment and installation costs, can be significantly reduced.The IMS provides innovative non-linear responses based on hydraulic load damping mechanisms. It includes a water-filled bladder housed in a braided rope and connected to an accumulator, functioning like a shock absorber. Increased mooring loads result in the pressurised rope extending and reducing the volume of the internal bladder. Active control of the pressure provides intelligent stiffness variations that can be tuned to reduce peak loads and control platform dynamics.

智能系泊项目**“ ** **智能系泊系统的季度尺度测试用于浮动海上风平台”是一个联合英国和美国协作项目，包括智能系泊设备，埃克塞特大学，PCCI，PCCI，INC和OCERGY INC，以及基于Ore急剧，US NAMERSIDER STRAPTION in US MORISER STRAPTION in US MORISER的进一步支持 technology, the University of Exeter provide modelling and the Dynamic Marine Component Test Facility (DMaC), PCCI are bespoke moorings specialists managing the sea trial deployment, Ocergy will provide platform interface support and end user feedback, the US Navy provide the WETS test facility, the ORE Catapult LCOE studies, NREL data acquisition and ABS Product Design Assessment and Certification support.The project undertakes coupled modelling, interfaces借助平台设计要求，并扩大了现有的IMS设计，以满足NREL 15MW参考涡轮机的四分之一尺度负载。它设计并构建了在美国海军湿润测试站点进行部署和测试的IMS系统，以证明IMS系统的运行性能可以提供大量的LCOE降低。MooringSystems是浮动装置的关键子系统，保证安全站保持保持站的保持和流体动力稳定性。系泊设备必须承受最终的负载条件以及循环疲劳负荷。需要超过50m的水深度浮动装置才能进入大部分全球海上风能。传统的系泊设计取决于油气领域的改编，这些改编可以满足所需的完整性和安全边缘，但导致了CAPEX密集型设计。系泊的资本成本是由极端（峰值负载）条件驱动的，而收入是在正常运营条件下产生的。如果可以减轻峰值负载，则可以大大降低系泊系统和相关结构元素的成本以及部署和安装成本。它包括一个充满水的膀胱，该膀胱装在编织的绳索中并连接到蓄能器，像减震器一样起作用。系泊负荷增加导致加压绳索延伸并减少内部膀胱的体积。压力的主动控制提供了智能刚度变化，可以调整以减少峰值负载和控制平台动力学。
