PLAT-0 2 - Proving a Low Cost, Composite, Buoyant, Mid-Stream Tidal Turbine Platform at Full-Scale

在该项目中成功开发和验证复合Plat-O浮力潮汐涡轮机平台将使潮流项目的部署成本减少50%，并将能源成本水平降低到商业GB 169/兆瓦时--在3年内将目前的数字减少四倍。通常，安装了昂贵的桩基或重力基座的海底潮汐涡轮机很难维护，而且使用昂贵的船只进行维护，这些船只的运行窗口很小。Plat-O是一种创新的中水而不是水面漂浮的潮汐涡轮机平台，具有小型船舶部署的低成本锚定技术。船上的绞车将设备拉到所需的深度，并将涡轮机放置在潮汐流最有效的部分。项目验证了100kW规模的钢制Plat-O结构，采用了车载功率调节电子设备和新颖的岩锚技术，然后开发了用于200kW示范的复合Plat-O#2结构。证明了使用组合结构可以减少载荷，提高使用寿命，以及复杂的系泊系统和系绳载荷。合作伙伴：可持续海洋能源有限公司和P E复合材料有限公司。

Successfully development and proving of the composite PLAT-O buoyant tidal turbine platform in this project will lead the way towards a 50% reduction in capex for deployment costs in tidal stream projects and bring levelised cost of energy down towards a commercial £169/MWh – a fourfold reduction on current figures within 3 years. Typically sea floor mounted with expensive piled or gravity bases tidal turbines are hard to maintain and use expensive vessels with small operational windows for maintenance. PLAT-O is an innovative mid-water, not surface floating, platform for tidal turbines has low cost anchoring technology deployed by small vessels. On-board winches pull the device to the required depth and turbines placed in the most effective part of the tidal stream. Project proves a 100kW scale steel PLAT-O structure with on-board power conditioning electronics and novel rock anchor technology before developing a composite PLAT-O #2 structure for a 200kW demonstration. Proves the use of composite structures to reduce loadings and improve life and the complex mooring system and tethering loads. Partners: Sustainable Marine Energy Ltd and P E Composites Ltd.
