How to find mooring wire Grade or MBL pressure?

[pacesetter]

Hi,

I need to cut a mooring wire and my cutter says it will cut a wire rope of 1770N/mm^2 or Grade 180. However, I only know the wire rope is diameter 90mm, 39.6kg/m and has a nominal breaking strength of 6800kN. How do I determine the grade or breaking stress of my wire rope?

Thanks

Mitigate the risk by using a stronger cutter? Other than that I would think you would need to know the construction of the wire and using that and you other data search through the supplier documentation and see which one fits.

If this is a wire in use it should have certification to go with it. This might also give you the information you need.

Hi, thanks for the reponse.

I do have a reference number for the certificate but it may be awhile before I can get it.

I have the Webtool RCV115 available to me. It can cut upto 115mm diameter wires so I am at about 78% of that for the diameter. Any experience with this tool?

Thanks

Hi,

I just found the report. The Steel grade is 1620N/mm^2 and all is good.

Thanks
