Hello,
This is a now-classic problem for Spectra lifelines, and we have tried a variety of methods to address it. One is the short bury option, and it makes some sense, given the relative loads. But it is, I think, a slippery slope; you can get away with it here, and then you see reports of tests showing even shorter splices holding to high efficiencies, and then splices get shorter and shorter until one fails, reminding us too late of the value of deep redundancy. I know, I know, it's just a gate, but my other objection is that cramming those two splices together is just ... inelegant. My usual practice is to make the upper and lower gates from a single piece, with the end passed through the standing part where it turns corners. But I also like the idea of a multiple Brummel, with a short bit of end buried for neatness.
No matter which option you choose, the really challenging bit is to have the gate come out the right length. Not much takeup available in those hooks.
Fair leads,
Brion Toss
