Anode Units for Oil Platforms
The anode unit is usually flange mounted in line with the strainer in the seawater stilling tube where it protects the pump above and the associated pipework system beyond. The design life of the anodes can be made to coincide with the scheduled maintenance period for the pump so that it is not necessary to lift or replace the anodes for up to 5 years.
Retrofit Anode Units for Oil Platforms In cases where access to deep well pumps is restricted or difficult, anodes can be installed at deck level. They can either be fitted directly within large diameter pipes or in the case of small bore pipework, an electrolysis tank housing the anodes can be fitted into the seawater pipework system. Anode units for Semi-Submersible Rigs The anodes can be mounted within the pontoons at the main seawater intake point where the ions of copper and aluminium are carried by the flow of seawater to give complete protection to associated pumps and pipework systems. |
