Based on statics and under simplified conditions,the force and failure mode of deepwater long-line rope aquaculture facility system were analyzed,and maximum tensions of the mooring rope in the system in different sea wave heights( 1-7 m) were calculated to compared to its breaking strength and mooring force of anchoring stake for evaluating anti-wave ability of the aquaculture facility. By this method,the model of evaluating anti-wave ability of deepwater long-line rope aquaculture facility was established. As an instance,the anti-wave abilities of two scales of deepwater long-line rope aquaculture facilities erected in 30-meter-deep sea waters of Zhangzidao farming sea area were analyzed by using the evaluation method and model. The results of the theory analysis showed that the anti-wave abilities of the two scales( 300 m and 200 m main rope length) of aquaculture facilities system were respectively 5-6 level of sea waves( 7-8 Beaufort wind scale) and 6-7 level of sea waves( 8-9 Beaufort wind scale) in the areas with the sea current of 1. 5m / s. By comparison,the calculation result of the maximum tensions of the mooring rope was fit with the actual measurement. Thus the method and model of evaluating anti-wave ability of deepwater long-line rope aquaculture facility could be referenced for designing the scales of deepwater long-line rope aquaculture facility in the preliminary design stage.
