First, I want to share with you some information and second i have a problem if you could help
I was working on Windcrete, the spar platform designed for supporting the IEA 15 MW. However, i could not find any information regrading the design of the tower. (it has been said in D1.3 “Public design and FAST models of the two 15 MW floaters” that the tower is made from concrete). I run a preliminary fatigue analysis considering normal conditions (Hs=2m, Tp=10s, wind speed =11 m/s) and obtain a tensile stress of order 5 MPa which is equal to the tensile strength of the concrete. That was surprising !!! meaning that the concrete will fail. I talked with the designers and they said they could not share the design of the tower but an initial compression is applied to the tower so the concrete will not fail ! (they did not mention that in the technical report). I was obliged to move to OC3 Hywind where the floater and the tower are made from steel. So be aware when dealing with Windcrete !!
Second, i succeeded to couple MoorDyn with MATLAB when using the mooring system of Windcrete (crowfoot mooring system). When i wanted to switch to OC3 Hywind, i got errors and i did not find out why although i was using the same input file of Windcrete (I just change the numerical values) and the same script also ! I dont know where is the problem. If someone could help
Here are the following input files for MoorDyn for Windcrete and OC3 Hywind respectively
