PROCESS & PIPELINE REPAIR
> Caisson Repair
> Caisson Liners
Due to their harsh environment, caissons can experience severe external corrosion at the waterline and galvanic corrosion / erosion at the pump string location. This can result in a lack of integrity, and occasionally result in part, or all of the caisson becoming detached and lost to the seabed. Should a caisson become detached this would pose a serious safety concern for a platform and risk damage to subsea pipelines and equipment, impacting on production and reputation.
External repair is often complicated by pipe supports and safe access close to the waterline. Caissons however, often offer direct bore access to the defect. Liners can be used to provide a solution to the above integrity issues and can reinforce the caisson. The liners can be designed to seal over / around a defect area, and can also mechanically grip the caisson above and below the defect / fracture / thinning therefore restoring structural integrity.
