This paper details the subsea corrosion protection system of the tension leg well platform (TLWP), which comprises coatings and cathodic protection (CP). Postinstallation surveys reveal potentials of at least 150 mV more protective than the minimum potential required for protection. The TLWP protection system weighs 434,000 lbm less than the conventional CP design, with 286,000 lbm less on the floating portion of the TLWP.
