Cold Stack Preservation of Jack-Up Rig

Cold Stack Preservation of Jack-Up Rig

Challenge

The client needed to mitigate corrosion of both external and internal metallic components and systems of a drilling rig in an aggressive marine environment throughout the duration of the cold stack.

Application

ElectriCorr® VpCI®-239 was used as an electrical contact and panel cleaner. VpCI®-101, VpCI®-111, VpCI®-132, and VpCI®-137 were inserted into electrical/electronic cabinets based on the volume of space needing protection. VpCI®-126 film was used to protect the externals of electrical/electronic cabinets located indoors, and MilCorr® VpCI® Shrink Film was applied to the externals of field (outdoor) electrical/electronic cabinets.

VpCI®-337 was fogged into tanks and piping for internal void space protection. VpCI®-609 was applied for internal protection of dry tanks. VpCI®-645 was used for flushing (with sea- water) and preservation of various piping systems. Rotating equipment and components were externally protected with VpCI®-369 and CorShield® VpCI®-369 (aerosol version). VpCI®-368 and CorShield® VpCI®-368 (aerosol version) were applied for external protec- tion of static components outdoors. M-531 served as a corrosion inhibiting oil additive for synthetic and mineral lubricants, and VpCI®-705 was used to preserve fuel oil tanks. Cor- rVerter® was applied to previously rusted components as needed. Various assets exposed to the atmosphere were wrapped in MilCorr® VpCI® Shrink Film for external protection. VpCI®-414 was used for cleaning/degreasing as needed during the preservation process.

Conclusion

The client had a much better experience with this preservation system than with other options used in the past. When the rig came back online in 2019, the client was satisfied with the ease of reactivation and had no notable concerns about corrosion.
