为了使升沉点吸收器发挥最佳性能，它必须设计成与主要海浪周期共振。因此，使海浪数据分析尽可能准确是很重要的。在这项研究中，现有的波浪条件数据被用来研究波浪数据的时间分辨率（每日和每小时）对设备设计和能量捕获的影响。研究了时间分辨率对海浪资源理论潜力估算的影响。结果表明，海浪数据的时间分辨率变化影响了装置的设计和功率捕获，但对理论功率资源评估没有显著影响。为墨西哥湾设计的装置还与俄勒冈州的波浪条件进行了分析，俄勒冈州的波浪资源理论潜力约为墨西哥湾的40倍。研究结果证实，由于该装置在墨西哥湾的海浪资源理论潜力要小得多，因此应该为特定的位置设计一种装置。最后，采用统计假设检验的方法研究了设计、直径和季节（夏季和冬季）对器件输出功率的影响。结果表明，这些参数对器件的功率捕获有显著影响。
For a heaving point absorber to perform optimally, it has to be designed to resonate to the prevailing ocean wave period. Hence, it is important to make the ocean wave data analysis to be as accurate as possible. In this study, existing wave condition data is used to investigate the effect of the temporal resolution (daily vs. hourly) of wave data on the design of the device and power capture. The temporal resolution effect on the estimation of ocean wave resource theoretical potential is also investigated. Results show that the temporal resolution variation of the ocean wave data affects the design of the device and its power capture, but the theoretical power resource assessment is not significantly affected. The device designed for the Gulf of Mexico is also analyzed with wave condition in Oregon, which has about 40 times the wave resource theoretical potential compared to the Gulf of Mexico. The results confirmed that a device should be designed for a specific location as the device performed better in the Gulf of Mexico, which has much less ocean wave resource theoretical potential. At last, the effect of the design, diameter and season (summer and winter) on the power output of the device is also investigated using statistical hypothesis testing methods. The results show that the power capture of a device is significantly affected by these parameters.
