The Stiesdal TetraSub platform for offshore wind turbine generators (WTG), is a semi-submersible floating concept comprising of three pairs of ballast tasks triangularly positioned around a central column. The floating foundation is moored by taut mooring lines that can be suitable for a range of water depths.Currently, as part of the front-end engineering design (FEED) process and load assessment, extreme wave loading on floating platforms is predicted using a combination of linear wave theory and the Morison equation, followed by the application of computational fluid dynamics (CFD) and finite element analysis (FEA). This approach leads to the creation of multiple system models which can be an inefficient and ineffective approach.Furthermore, similar methods are applied when predicting wave run-up on floating structures; this is typically estimated using model scale tank testing combined with CFD results. As with predicting extreme loads, these methods have a number of shortcomings, leading to over-engineered systems, which effect the operation, survivability, and cost of the system

STIESDAL TETRASUB平台用于海上风力涡轮机发电机（WTG），是一个半可见的浮动概念，该概念由三对镇流器任务组成，该算法围绕中央列围绕三角形。浮动基础被拉紧的系泊线停泊，可以适合一系列水深。目前，作为前端工程设计（FEED）过程和负载评估的一部分，使用线性波理论和Morison方程的组合预测了浮动平台上的极端波负载，然后是计算流体动力学（CFD）的应用。这种方法导致创建多个系统模型，这些模型可能是一种效率低下且无效。通常使用模型量表测试与CFD结果相结合来估算这一点。与预测极端负载一样，这些方法具有许多缺点，导致了过度设计的系统，从而影响系统的运行，生存能力和成本
