Oil & Gas (OILG)



Ships and Offshore Structures (SOS)


Customer Location:

Offshore oil production platform, China


Application Date:

April 2006


Application Situation:

Damaged cladding on riser.



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



Belzona 1161 (Super UW-Metal)

Belzona 5831 (ST Barrier)



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.
