There are significant differences between protecting FPSOs/FSOs and normal seagoing vessels against hull corrosion.
The most important is that FPSOs/FSOs generally remain on station for many years without drydocking. Therefore, it is an advantage if key components such as anodes and reference electrodes are diver changeable.
Another factor which needs to be taken into consideration is the ‘current drain’ caused by anchor chains.
In most cases PSOs and FSOs are supplied with forward and aft ICCP systems. Because the vessel is stationary when in operation, both of these systems have a similar output, generally in the region of 300amps.
Cathelco’s new range of C-Max anodes are diver changeable and emit a powerful current from a relatively small surface area. This means that fewer anodes are required and the number of hull penetrations is subsequently reduced. Features include self-snapping torque nuts which speed up the installation process.
