Cathodic protection for sea cables

A cathodic protection system for sea cables will extend the lifespan and reduce maintenance cost.

Mechanical durability of sea crossing power transmission cables are crucial. Corrosion of the outer steel armouring can significantly reduce the lifetime of  sea cables.

Design of cathodic protection systems for sea cables is rather straight forward. However, the landfall areas could be challenging with regards to power availability and weather condition. Our designers can make decisions that reduce safety risk and cost during the construction stage, but also during subsequent use and maintenance.
