Industry:

Oil & Gas (OILG)

 
 

Application:

Ships and Offshore Structures (SOS)

 
 

Customer Location:

Offshore oil production platform, China

 
 

Application Date:

April 2006

 
 

Application Situation:

Damaged cladding on riser.

 
 

Problem:

The riser cladding was damaged due to abrasion. This needed repairing before corrosion compromised the integrity of the riser.

 
 

Products:

Belzona 1161 (Super UW-Metal)

Belzona 5831 (ST Barrier)

 

Substrate:

Carbon Steel

 
 

Application Method:

Application was carried out using a modified version of Belzona Know-How System Leaflet SOS-21. After surface preparation with a disc grinder, Belzona 1161 was used to rebuild the damaged area before overcoating with Belzona 5831 to protect the riser from further corrosion.

 
 

Belzona Facts:

Belzona surface tolerant products provide excellent adhesion and long term performance in these difficult to access areas subject to splashing and immersion during the application process.
