Experimental study on the hydrodynamic characteristics of a combined structure of offshore wind turbine jacket and net cage
[Objective]This paper proposes a novel structure that combines an offshore wind turbine jacket and aquaculture net cage,and its hydrodynamic characteristics are investigated.[Methods]Experimental tests are carried out to analyze the horizontal loads on the pile foundations of the combined structure,and the tension in the connection between the jacket and net cage,while considering the effects of water depth,wave height,wave period,wave direction,current velocity and direction,and other parameters.[Results]For 0-degree regular wave conditions,the maximum horizontal load on the pile foundations is 30.2 N.For 45-degree regular wave conditions,the maximum horizontal load on the pile foundations is 27.5 N.Thus,the maximum horizontal load on the pile foundations under 0-degree regular wave conditions is 9.5%greater than that under 45-degree regular wave conditions.[Conclusions]Under regular wave conditions,the net cage has little in-fluence on the horizontal load on the pile foundations when the wave period is small,while under pure current conditions,the net cage will cause a significant increase in the horizontal load on the pile foundations of the combined structure.
