TLPWIND UK: "Driving the cost down of offshore wind in UK Waters"

英国目前在全球海上风电市场处于领先地位。很明显，我们需要开发新技术，以帮助我们在建设英国制造业的同时减少电费。在过去的四年里，Iberdrola一直在开发一种创新的浮动基础概念TLPWIND，以帮助降低OW的电力成本。浮动的基础将通过一套张力索系统固定在海床上，该系统将几乎完全限制其运动。它的主要尺寸和钢材重量经过精心优化，制造成本降至最低。TLPWIND概念使风力涡轮机在陆上可控环境中组装，从而实现更高效、更低成本的运输和安装（“T&I”）。这大大减少了海上作业和昂贵的重型安装船的使用，从而降低了T&I成本。这种方法旨在降低海上风电项目的风险，特别是在保险公司和金融家看来，从而增加投资者对OW项目的信心和承诺。该项目旨在使这种半成熟的概念适应英国的现场条件（50-60米以上），并有助于降低整体LCOE。

The UK is currently leading the offshore wind (OW) market worldwide. There is a clear need for developing new technologies that will help cut our electricity bills whilst building a UK manufacturing industry. Iberdrola has been developing an innovative floating foundation concept, TLPWIND, during the last four years to help reduce the costs of electricity from OW. The floating foundation will be moored to the seabed using a tensioned cable system that will restrict its motion almost entirely. It’s main dimensions and steel weight have been carefully optimised and its fabrication costs minimised. The TLPWIND concept enables more efficient and reduced cost transportation and installation (“T&I”) with the wind turbine being assembled onshore, in a controlled environment. This heavily reduces offshore operations and the use of expensive heavy installation vessels, and thus T&I costs. This approach is intended to de-risk offshore wind projects, particularly in the view of Insurers and Financiers, and consequently increase investor confidence and commitment to OW projects. This project aims to adapt this semi-mature concept to UK site conditions (50-60m plus) and help reduce overall LCOE.
