Tension leg platform (TLP) wind turbines are proposed as a solution for offshore floatingwind turbines to reduce the footprint of the mooring system whilst also enhancing systemstability and removing a large amount of mass compared to other floating foundation types.However, the high tensions in the tendons transfer large uplift forces into the anchors whilstconservatism in the traditional offshore industry leads to large safety factors being used indesign. This has caused the anchor systems for TLPs to be unaffordable for floating windprojects. Through OrcaFlex analysis of two TLP platform concepts, the most onerous casesfor anchor loading will be investigated. Using these load cases, suction caisson anchors,alongside some novel anchor designs, will be tested using the ORE Catapult's scaled anchortest rig. Using the outputs of the testing, alongside other technical and economic factors,a holistic methodology for comparison of anchors will be developed to enable the selectionand sizing of anchors for TLP projects. This will help to reduce the cost of TLP floatingoffshore wind, which is seen as the major barrier to the adoption of the technology atpresent.

张力腿平台（TLP）风力涡轮机被提议作为海上浮动风力涡轮机的解决方案，以减少系泊系统的占地面积，同时增强系统稳定性，并与其他浮动基础类型相比消除大量质量。然而，钢筋束中的高张力将大的上举力传递到锚，而传统海上工业中的保守主义导致设计中使用大的安全系数。这导致TLP的锚系统对于浮式风电项目来说是无法承受的。通过OrcaFlex对两个TLP平台概念的分析，将研究锚荷载最大的情况。使用这些荷载工况，吸力沉箱锚以及一些新颖的锚设计将使用ORE Catapult的比例锚试验台进行测试。利用测试结果以及其他技术和经济因素，将开发一种比较锚杆的整体方法，以便为TLP项目选择和确定锚杆尺寸。这将有助于降低TLP浮式海上风电的成本，这被视为目前采用该技术的主要障碍。
