Regulatory Agency Accepts Belzona® Superwrap II

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

 
 

Customer Location:

Gulf of Mexico, USA

 
 

Application Date:

October 2016

 
 

Application Situation:

Offshore platform with leaking pipe

 
 

Problem:

The customer had a section of pipe with external corrosion problems and several through wall defects. Traditional cut and replace alternatives would require costly shutoff of the platform. The entire pipe was welded in place and there were no flanged connections to make a spool swap. An engineered solution was required by the regulatory agency that oversees the platform.

Six feet of 20” pipe was wrapped together with two feet of 1” pipe, and two feet of 3” pipe. Three Belzona Super Wrap II designs were used to address different defect locations, ranging from three to seven wraps.
