ADCP断面已用于英国彭布罗克郡拉姆齐湾地区的潮流资源调查。以前的资源评估表明，该地区是英国潮汐流部署最有前途的地区之一，这一贡献证实了该地区的商业可行性。在这项研究中，考虑了三个通道：拉姆齐湾本身和两个由近海小岛形成的西部通道。流速被用来计算通过渠道的潮汐能通量。通过三个通道的最大瞬时峰值通量范围为180 MW至70 MW。介绍了通量横截面，并说明和讨论了中尺度水深特征对通量和对整个潮汐周期最大通量横截面变化的影响。计算了可提取功率潜力的理论值，范围在7.2 MW和21.8 MW之间。这些值大约是通过测量横截面的平均通量的1/4。一个通道被确定为是优选的阵列部署的第一阶段给定的最大均匀性的通量通过通道横截面，它具有最高的功率潜力。
ADCP transects have used to characterise tidal stream resources in the Ramsey Sound area of Pembrokeshire, UK. Previous resource assessments have previously suggested that this area is one of the most promising for tidal stream deployments in the UK and this contribution confirms the commercial viability of the area. In this study three channels were considered: Ramsey Sound itself and two channels to the west formed by small offshore islands. Current velocities were used to compute the tidal energy flux through the channels. Maximum instantaneous peak flux through the three channels ranges from 180 MW to 70 MW. Flux cross-sections are presented and the impact of meso-scale bathymetric features on flux and on the cross-transect variation of maximum flux over the tidal cycle is described and discussed. Theoretical values of extractable power potential are calculated and range between 7.2 MW and 21.8 MW. These values are approximately ¼ of the average flux through the measured cross-section. One channel is identified as being preferable for the first stage of array deployments given greatest homogeneity of flux through the channel cross-section and it having the highest power potential.
