Glad you got something working.
And for your reference, I tracked down the memory issues that caused FAST v8 to produce segmentation faults on the offshore cases when compiled in gfortran. If you use the files in the link on my April 30, 2015 post here: Precone angle in WTPERF), you should be able to get FAST v8.10 to work on gfortran.
This will be fixed in the next release of FAST v8.
