NACE 02064 - Laboratory Investigation of Corrosion and Corrosion Protection of a Candidate Umbilical Material for Subsea Production Service

Umbilical functionality is critical to proper operation of subsea production systems, and for this reason it is important to properly select materials and corrosion protection options for this service. In this regard, specimens of a chromium-manganese-nickel duplex stainless steel (UNS S32001) in the normal, welded, and crevice conditions were exposed freely corroding and cathodically polarized for up to 413 days in natural sea water environments that were intended to simulate umbilical service.
