The influence of an annular moonpool on towing resistance of ocean nuclear energy platform
The offshore nuclear power platform needs to be towed to the port for refueling every two to three years,so it is very important to study the towing resistance of the offshore nuclear power platform at the initial stage of its design.Considering two concepts of offshore nuclear power platform,the influence of annular lunar pool on the towing resistance of the platform was studied.The towing resistance of separate offshore nuclear power platform and integrated offshore nuclear power platform at different towing speeds is calculated by using STAR-CCM+software.The results show that the towing resistance increases obviously with the increase of towing speed.The presence of lunar pool makes the flow field around the platform tend to be disturbed,which leads to the increase of towing resistance of the nuclear platform.The analysis of the lunar pool drag increase mechanism can provide reference for the design of nuclear power platform.
