Riser Boot Sealed With Belzona

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Ships and Offshore Structures (SOS)

 
 

Customer Location:

Oil and Gas Industry, North Sea, Norway

 
 

Application Date:

July 2003

 
 

Application Situation:

Oil riser pipes at a North Sea platform off the coast of Norway.

 
 

Problem:

The customer was concerned that after replacing damaged neoprene, water would penetrate between the riser and the cladding onto glassflake coating and cause disbondment.

 
 

Products:

Belzona 2121 (D & A Hi-Coat Elastomer)

 

Substrate:

Glassflake coating and neoprene

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet SOS-21. Application was carried out using rope access to suspend operatives beneath the platform. The Belzona 2121 system was applied to encapsulate the new neoprene cladding to glassfllake coating on the riser.

 
 

Belzona Facts:

Belzona was chosen due to its high adhesion to both neoprene and glassflake. Another advantage for the applicators was the relative ease of application of the Belzona products. As of February 2015 the application is still in perfect condition.
