Shenzi Stainless Steel Coating Project; New Paint Trials
Scope
The intent of the new paint trials is to assess the performance of two alternative coating systems
(manufactured by Belzona and Chemco), for use to coat the presently uncoated stainless steel piping at
the Shenzi facility. The systems trialed will be compared to the regularly used Carboline system and
recommendation made for a path forward.
The two trial coating systems were applied, together with the Carboline system, alongside each other on
parallel piping. The systems were all applied using the same surface preparation and under comparable
conditions. Two areas were selected for the trial, a vertical section which allows the pipe to be viewed
at deck level, and an at height horizontal piping section which is more representative of the typical
stainless steel piping arrangement at Shenzi. Both trial areas are on the Production Deck on the South
side of the Facility. The trial areas are illustrated in the photographs below.
