Corrosion is known to be a main damage mechanism deteriorating the structural integrity of offshore structures. Cathodic protection (CP) has been used as a primary method to control the corrosion of metal in conjunction with organic coating. Recently the importance of CP is being gradually highlighted with a demand for long lasting design life of offshore structure so that the long-term electrochemical performance of CP becomes a key concern to ensure the structural integrity.Design current density is one of the CP design parameters determining the total anode mass and the valid service life of CP systems which is greatly influenced by temperature. However it is hard to find studies dealing with the effect of temperature on the CP design. Although industrial standards (e.g. Class rule NORSOK NACE andISO) suggest guidelines for general CP design they cannot provide quantitative information on the protection potential and the life of the system according to service temperature.In the present study temperature effect on the design current density will be introduced based on experiments using various electrochemical methods and a case study on the optimization of CP design for the FPSO (Floating Production Storage and Offloading) using computational analysis tool (BEASY S/W) will be presented.

Key words: cathodic protection, corrosion, computational analysis

This paper reviews the concerns of applying excessive levels of cathodic protection current to pipelines and the need for establishing an upper potential limit. Coating disbondment, hydrogen induced stress cracks, stress corrosion cracking, hard spots and the problems associated with measurement of a true polarized pipe-to-electrolyte potential are addressed.
