We had probs with ‘z kinks’ in our Seaeye tether in Brunei this year. We were told that if the tether is ordered ‘unterminated’, then it is sent direct to you from a third party that Seaeye have contracted to manufacture the tether – it is then at the mercy of that contractors supposed QC department. If the tether is ordered ‘terminated’ at either end, then it is sent from the manufacturer to Seaeye for terminating and checks, before being sent out to you.
Don’t know the science behind the failures but over the years, any time i have played with a z kinked tether, i have experienced more frequent trips and reterms. 🙁
