Challenge
The client’s rig did not take a new contract and was expected to be idle for at least twelve months. The client decided to cold stack the rig.
Application
Cortec® was consulted to provide best-in-class products along with after-sales support for application and dosage requirements to preserve all systems on the rig. A particular focus was placed on ensuring oil-based additives were fully compatible with the original oils and that the rig could be returned to operation with minimal overhaul or work being conducted.
M-531, VpCI®-322, and VpCI®-329 were added to the oil systems. VpCI®-645 was used during the flushing of piping and tanks with seawater. VpCI®-609 S was used for the internal protection of bulk tanks. VpCI®-337 was used for other internal equipment voids. ElectriCorr® VpCI®-238 was used for cleaning, surface prep, and protection of electronic and electrical equipment. VpCI®-101 and VpCI®-111 emitters were also placed inside electronics and electrical (e.g., junction boxes) according to size. MilCorr® was shrink-wrapped around various on-deck equipment—everything from cranes and winches to junction boxes. VpCI®-126 was applied similarly to equipment located indoors. VpCI®- 137 was placed inside lifeboats and other equipment wrapped with VpCI® film. VpCI®-416 was used as needed for cleaning/degreasing throughout the rig. VpCI®-368 was coated on unpainted surfaces of bolts, flanges, and other atmospherically exposed equipment outdoors. VpCI®-369 and CorrLube™ VpCI® Lithium EP Grease were applied as needed on surfaces of rotating or reciprocating equipment outdoors or indoors. CorrVerter® served as a rust converter for touchups of various painted surfaces.
Conclusion
Cortec® supported their client with immediately available stacking materials to effectively preserve the jack-up rig until a contract would be available for it to return to work.
