SISProtect - Self Installing Scour Protection for Offshore Wind Farms

“SISProtect将开发并展示一种解决方案，以解决与当前冲刷保护系统相关的施工和运维成本、健康、安全和环境因素。冲刷是由流动的水引起的海底侵蚀，例如在海上环境中，海流/波浪导致海上风力涡轮机基础和其他资产（如海底电缆等）周围的沙质海床被侵蚀。sisprotect将为该问题提供具有成本效益的长期（永久）解决方案，如果不采取适当措施，可能会使海上风电行业损失巨大。导致海上风力发电厂安装的能源成本更高。SSCS的前沿垫系统是“人造海藻”垫，在提供强大的冲刷保护的同时，提供了成本、卫生和安全以及环境效益。这是通过以下方式实现的：在陆上设施的安全范围内，设计并安装在基础上的经济高效的冲刷保护系统；与现有解决方案相比，缩短了部署时间；与岩石和其他“常规”方法相比，该系统不需要持续维护；不需要大型的重型起重/卸石船，从而减少了柴油的使用和海上H&S问题的机会；利用环境可接受的材料来重建自然的防止冲刷的方法。虽然前沿垫概念已经在石油和天然气领域的水深达100米以上的地方得到了现场验证，但如果没有像该项目这样的机会，迄今为止还不可能对海上风力发电场涡轮机基础的垫部署方法进行建模和调整。该项目的主要考虑因素是由SPT Offshore开发的创新部署系统，该系统将在施工期间与基础结合，并在基础安装期间自动部署front Mats。因此，这种自部署系统将不再需要单独的海上作业来安装防冲刷装置，从而大大节省了成本，并减少了与海上作业相关的HSE影响。将开发一个特定的部署系统来实现这一目标，并设计和制造适合该系统的front Mats。成功完成后，英国将开发出全球独一无二的解决方案，仅在英国就能为项目节省1.5亿至2亿英镑，全球预计可节省数十亿英镑。”

"SISProtect will develop and demonstrate a solution to address the construction and O&M costs, health and safety and environmental factors associated with current scour protection systems. Scour is the erosion of the seabed caused by moving water such as those commonly experienced in offshore environments where the sea currents / waves cause sandy seabeds to become eroded around offshore wind turbine foundations and other assets such as subsea cables, etc.SISProtect will provide a cost effective and long term (permanent) solution for this issue which can cost the offshore wind industry significantly if suitable measures are not taken, resulting in higher costs of energy from the offshore wind farm installations.The SSCS Frond Mat system, which are mats of 'artificial seaweed' provides cost, H&S, and environmental benefits whilst providing robust scour protection. This is achieved through: A cost effective scour protection system engineered and installed to the foundation within the safety and security of an onshore facility; improved deployment times when compared with existing solutions; the system requires no ongoing maintenance in contrast to rocks and other 'conventional' methods; no need for large heavy lift / rock dumping vessels thereby reducing diesel usage and opportunities for H&S issues offshore; the environment by utilising environmentally accepted materials to recreate natures method of scour prevention.Whilst frond mat concept has been field proven in the Oil and Gas sector in water depths of up to and over 100m, it has not been possible to date to model and adapt the Mats deployment methodology specifically for offshore wind farm turbine foundations without an opportunity such as the one being offered by this project.The main consideration for this project is the innovative deployment system, developed by SPT Offshore, that would be incorporated with the foundation during construction and would automatically deploy the Frond Mats during foundation installation. This self-deployment system would therefore eliminate the need for separate offshore operations to install scour protection resulting in significant cost savings, as well as reducing the HSE impact associated with offshore operations. A specific deployment system will be developed to achieve this, along with Frond Mats designed and manufactured to suit the system. Successful completion will see a globally unique solution developed in the UK capable of saving £150-200m for project in the UK alone, comfortably allowing estimating savings in the £billions globally."
