Remediation of Corrosion Under Pipe Support (CUPS) by Trenton Wax-Tapes
Challenges
Corrosion under pipe support (CUPS) is a major hidden threat and one of the most aggressive types of corrosion attack on piping systems. CUPS is caused by several factors. Traditionally, the design of pipe supports allows for crevices to be formed which can lead to crevice corrosion in the presence of moisture. Protective coating damages, metal to metal contact and galvanic corrosion also lead to CUPS. The most common causes of external piping failure in ageing assets are due to highly localised deterioration by corrosion in areas which are less accessible and difficult to inspect and repair. As a result, operators may face huge pipe replacement costs, loss of pressure containment and production or in some cases, explosion and massive economic consequences.

Platform Deployed CP Retrofit: A Cost-Effective Solution For Extending Cathodic Protection Life of Offshore Platforms
The Challenge
Extension of the cathodic protection (CP) life of an existing offshore platform is a challenging but mandatory task to maintain the adequate CP level and avoid marine corrosion. Conventional CP retrofit methodologies require underwater intervention and vessel, which are very costly, especially for structures that are located in saturation diving depth. In partnership with Galvotec Corrosion Services (GCS) of the USA, IEV is launching two Platform Deployed CP Retrofit technologies as part of its portfolio of corrosion control solutions to enable its offshore oil and gas clients to lower the cost of extending cathodic protection life on existing facilities.
