项目摘要

The tidal renewable energy sector is at a stage where it is going to expand with larger devices and arrays of devices. An estimation of nearly 4GW of installed capacity by 2020 is likely by 2020, enabling the sector to make a serious contribution to the energy requirement. Moving the sector forward from its current infancy still requires evelopment of fundamental aspects of the technology in order to provide greater cost efficiency. One particular area is to significantly reduce the cost of deployment and recovery for maintenance. Given the harsh environment in which the devices are deployed and the costs associated with the vessels, the speed of recovery is essential to reducing the life costs associated with the energy generated over a device lifetime.Hence the urgent need to reduce the installation and maintenance costs of the DeltaStream system. The current project proposes an effective wet-mate nacelle removal system for cost-effective installation and recovery.Cardiff University will assess the lifting dynamics involved in lowering the turbine from the surface of the sea onto the structure and evaluate the connection aspects of the novel design of the Deltastream. Integrated with physical testing by the project partners, the data will provide feedback to the industrial partner to assess any modifications needed to the proposed designThis Work Package focuses specifically on the modelling the dynamics of lowering the turbine from the surface of the sea into the wet-mate socket. Specifically Ansys software will be used for the modelling. The outputs of the workpackage will also provide feedback to the component testing and final device assembly undertaken as part of the overall project.

潮汐可再生能源行业正处于一个阶段，它将通过更大的设备和设备阵列进行扩张。据估计，到2020年，装机容量可能达到近4千兆瓦，使该行业能够为能源需求做出重大贡献。将该部门从目前的初级阶段向前推进，仍然需要开发该技术的基本方面，以便提供更大的成本效益。一个特别的领域是大幅降低部署和恢复维护的费用。考虑到设备所处的恶劣环境和与船只相关的成本，恢复的速度对于降低与设备生命周期产生的能量相关的寿命成本至关重要。因此，迫切需要降低DeltaStream系统的安装和维护成本。目前的项目提出了一种有效的湿伴侣吊舱移除系统，以实现经济高效的安装和回收。卡迪夫大学将评估将涡轮机从海面降到结构上所涉及的提升动力学，并评估DeltaStream的新颖设计的连接方面。结合项目合作伙伴的实物测试，数据将向工业合作伙伴提供反馈，以评估对拟议设计所需的任何修改。该工作包专门侧重于对涡轮机从海面降至湿法配合插座的动态进行建模。具体来说，将使用Ansys软件进行建模。工作包的产出还将向作为整个项目一部分进行的部件测试和最终设备组装提供反馈。
