An offshore oil platform located off Western Australia had been installed with uncoated conductors. The lack of protective coating resulted in significant corrosion damage that was only expected to get worse over time.
The problem of coating the conductors was more challenging than most as the area of concern lay in the splash zone, rendering many traditional protection options very difficult to implement, both from a surface preparation and a coating standpoint.
The client was seeking a durable and long term solution for the splash zone that could remove the large cost associated with divers, dive spreads and dive support vessels and the safety risk of divers in the splash zone.
The project had the following specifications:
Structure | Steel conductors |
Application Type | Diverless FRP protection |
Operating Environment | Splash Zone |
Quantity | 5 conductors |
Dimension | 500mm |
Design Temperature | 65oC |
Design Life | 20 years |
Surface Preparation | WJ1 |
Weight of Repair | 30kg per half shell |
Corrosion Type | External |
