By "the two models", I mean Test25 that NREL has distributed (model 1) and your model (model 2) are different.

I'm sorry, but I don't understand where you getting your numbers from. Where are you getting?

- Total mooring pretension, T=6358481.025 N
- Total Mass (Including water ballast), m=22043356 kg
- Even if these values are correct, I'm not calculating T+mg = 137187702.505 N or V=13706.044 m3

I'm also not sure where your file DeepCwind.MAP.sum came from. This appears to be a MAP++ summary file, but your FAST model says you are using MoorDyn instead of MAP++, so, I'm confused. I also noticed that your MoorDyn model uses an anchor depth of 200 m while your MAP++ model is using an anchor depth of 250 m.

Best regards,
