Course Overview:
This training course is about the basic concepts and methods of fighting corrosion, particularly regarding the use of cathodic protection systems. Among other phenomena of the cathodic protection offshore design, participants will be taught about the nature of corrosion, effects of regional soil conditions, and system protection.
The course involves the design, installation, testing and repairs of cathodic protection systems, particularly sacrificial anode systems, impressed current systems and corrosion monitoring methods.
It also includes specification of materials, coatings, and specialized survey methods in order to significantly assess system performance.
The program is applicable to engineers, technicians and maintenance personnel engaged in cathodic protection in various areas including pipeline design, marine structures, and offshore activities.
