Yes,on an initial glance this site looks to hold some useful stuff with regard to pipeline construction. The repository seems to hold a variety of material which I would like time to peruse.
I do get to download some of the posts but generally these are for later review when and if time permits. So far the vast majority has been discarded but as the excelcalcs site has developed I have found more pertinent info posted. Sadly I have yet to find anything that I am able to utilise and again time permitting I may even get to upload some of my own calcs when I can round to tarting them up for presentation.
In the interim, here is another site that I have used on occaision that has come up with some gold in the past.
