Madcon Corporation has been awarded the U.S. patent number, 6,536,991, for its Structural Composite Retrofit System. Utilizing composite materials, the system provides full structural restoration of damaged or corroded tubular members such as drive pipe casing, conductors, jacket legs and bracing, concrete or steel piling, and risers/pipelines. The system can also be used to upgrade the original design capacity of platform members. Several major offshore owner operators recently installed the Structural Composite Retrofit System from the (-15) to (+60) elevation to rebuild extremely corroded drive pipe casing. The company also has a patent pending on its method to repair damaged or collapsed casing in gas and oil wells.
