    Line Tension v. Strain Testing

    DaveVikingPE, There is a small section giving the basic information on the anchor and mooring line under "The Technology" section. Discussion on the mooring line failures we have experiences in the filed are also under the “Field Experience” section. The buoy is on a slack line mooring. The...

    Line Tension v. Strain Testing

    Thanks Compositepro for the help. I was wondering if someone had encountered this behavior before and it was just something I was unfamiliar with. I figured I would check here before I started dissecting our procedures to see what went wrong. I'm guessing that it might be in our displacement...

    Line Tension v. Strain Testing

    Compositepro, Thanks for you responce. Wouldn't you expect to see some length offset if the line were taking a set? We are mesureing a section of the line to find strain and there it is roughly the same size when we relax back to 100 lbs. as it was before we ramped it up the first time...

    Line Tension v. Strain Testing

    Thanks all, This braided line is designed to have zero twist, and does not show signs of twisting during testing. We have two to linear displacement measurement instruments fixed to either side of a section of known length of the line. Taking the difference between these two readings give us...

    Line Tension v. Strain Testing

    I have a new multi-fiber braided mooring line that is to be used for deep sea buoy moorings. I need to generate a function for axial stiffness (EA) in order to model this line in a computer program. We have a line tester and have generated a Tension v. Strain curves, which are expectedly...
