The sites are quite remote 1000's of KM away from nearest PDA. Gates seems to provide a reasonable alternative to ENR. I’ve noted that the capacity requirements appear to less stringent or volatile with Gates in most cases.
When I compared the factored equations ENR @ FS=3, ENR @ FS=6, and Gates @ FS=3.5, the results are all over the map. The gates formula seems to be more stable.
The ENR @ FS=3 and Gates seem to be correlate up to around 300 KN at lower energy ratings, and up to 600 KN and higher values. Can anyone give recommendation on when to not apply equations, i.e. (less the 400-500 KN) See attachments.
