Tower mass in the excel can not match our calculated value #130

Dear developers,

I and my colleague are modelling 15 MW wind turbine in Simpack. After our modelling based on the tower properties in the excel file (https://github.com/IEAWindTask37/IEA-15-240-RWT/blob/master/Documentation/IEA-15-240-RWT_tabular.xlsx), we checked the tower mass in Simpack. It showed that this tower has a mass of 1332.8 t. This value (1332.8 t) can not match the tower mass in the excel file which is 853.46 t.

We even noticed that in Table 1.1 of the documentation (https://www.nrel.gov/docs/fy20osti/75698.pdf) the tower mass for 10 MW wind turbine is 987 t, which is larger than 15 MW tower mass mentioned in the excel file. To our surprise, we had initially assumed 15 MW tower mass should be heavier than 10 MW before we read this documentation.

Therefore, we want to confirm here whether the correct tower mass for this 15 MW wind turbine is or is not 853.46 t?

Regards,

Sorry for this issue. Possibly something wrong in our simpack model. And the excel file should be correct as our calculation of tower mass by hand is ~800t.

Regards,
