I want to design the mooring system of a floating offshore wind turbine. When I checked the mooring properties of OC3-Hywind and OC4-DeepCwind, I found that the mooring line diameter of OC4-DeepCwind is thinner than that of OC3-Hywind, but the mass density of OC4-DeepCwind is larger than that of OC3-Hywind. Could you tell me how do you determine these properties?
When I design the mooring system, I need to choose the mooring line type according to code. I have read API_RK_2SK and DNVGL-OS-E301, but I didn’t find a table that can be used to choose the mooring line type. Could you tell me which code should I use?
