From Edgar Matamoros of Estrumet Metalmecanica SA on September 28, 2016:
I just found this post made by myself 4 years ago! I completely forgot I made it!! We did made the inspection I mentioned and the results were excellent! Certainly this is a method I would recommend!

From Alfredo Claussen of Instituto Mexicano del Petroleo on October 23, 2015:
Whatever the selected method, we must keep in mind that catastrophic cable failures have occurred: a large offshore platform topsides module was completely lost when the lifting cable ruptured because of hidden corrosión inside it. That cable had been subjected to immersion in seawater in a previous installation, and the corrective measures were ineffective. Search for "Petronius lifting accident" for the complete story.

From keith ridley of rigblast on October 20, 2015:
Use zinc paste, the wrap in PVC.

From William Feliciano of NYS Dept. of Transportation on October 11, 2012:

     For the older suspension bridges, dehumidifcation may not be an option. Here, barrier and inhibitive coatings may provide a belt and suspenders approach - a flexible, waterproof coating applied over a circumferential wire wrapping, with an inhibitive red lead paste within the cable has been considered the "tried and true" approach dating back to John Roebling and the Brooklyn Bridge.       

     Special attention must be given to where the saddles are, to make sure that these protective systems are not compromised at these locations.

From BALOJI NAIK RAMAVATH of Naval Materials Research Laboratory on October 4, 2012:
Metallic coatings.

From Bill Brooks of AECOM on October 2, 2012:
     Moisture within suspension cables is the primary cause of corrosion. Wrapping the cables with a waterproof membrane and installing a dehumidification system is the most effective means of arresting corrosion. Such systems are more common in the U.K. and in Asian countries, but are slowly beginning to catch-on in the U.S.

From Edgar Matamoros of Estrumet Metalmecanica SA on October 11, 2012:
     We  used Cableguard® in 2006 for a new suspension system installed in a 55-year-old bridge. We will do an inspection of the condition of the cables under the wrapping in the following month. We will be checking for signs of humidity inside the cable groups. Will post our findings...
