Belzona® Helps Protect Offshore Platform Legs At Waterline

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Ships and Offshore Structures (SOS)

 
 

Customer Location:

Major Oil & Gas Producer, Gulf of Mexico

 
 

Application Date:

May, 2010

 
 

Application Situation:

Platform legs damaged by corrosion and impact from service/crew boats at the waterline.

 
 

Problem:

Due to corrosion and impact damage platform legs were at risk of losing structural integrity. Client wanted to terminate damage to avoid further deterioration. Customer had welded top and sides of halfwrap without welding bottom, due to water/wave action. Corrosion had actually accelerated between the leg and halfwrap.

 
 

Products:

Belzona® 1161 (Super UW Metal)

Belzona® 5831 (ST Barrier)

 

Substrate:

Carbon Steel

 
 

Application Method:

Application was carried out in accordance with modified Belzona Know-How System Leaflet SOS-8. Belzona 1161 was used to seal the bottom of split shells, and Belzona 5831 was then injected to fill cavity between platform leg and steel wrap.

 
 

Belzona Facts:

 Customer came to local Belzona Distributor for solution. Belzona surface tolerant materials allowed area to be completely sealed. Thus the possibility of corrosion was eleminated. Customer has completed 32 leg repairs and scheduled more for the next few years.
