NATURE OF DEFECT
The motor cooling header had suffered from external corrosion, resulting in two large corrosion areas with through-wall defects. The client required a composite repair to restore the header to its original design specification whilst avoiding replacement of the component.
SOLUTION
Metalyte Pipeworks produced an engineered composite repair solution designed in accordance with ISO 24817. During the repair, additional deterioration and a compromised gasket were identified, requiring the repair design to be modified on site to ensure the long-term integrity of the header.
REPAIR METHOD
The repair area was prepared before restoring the original profile and installing an engineered Dragon-Q-UHT composite repair system. Following controlled heat curing, the repair underwent hardness testing, protective coating application and final quality assurance prior to completion.
OUTCOME
The engineered composite repair was successfully completed, restoring the motor cooling header to its original design specification. The repair was completed offshore whilst avoiding replacement of the header and minimising disruption to operations.
